Transistors have changed the area of electronics as one of the most important components of an electronic circuit. These three-terminal semiconductor devices have been around for more than five decades. They’re frequently employed as amplifiers and switches. Because they can turn something “on” or “off” without moving parts, you can think of them as relays without moving parts.

A. Structure

In the beginning, germanium was utilised to make extremely temperature-sensitive transistors. They are now built of Silicon, a semiconductor substance found in sand, because Silicon transistors are significantly more temperature-tolerant and less expensive to produce. Bipolar Junction Transistors (BJT) are divided into two types: NPN and PNP. Base (b), collector (c), and emitter (e) are the three pins of each transistor (e). The layers of semiconductor material utilised to construct the transistor are referred to as NPN and PNP.

B. What Is It and How Does It Work?

An NPN transistor is created by sandwiching a p-type silicon slab between two n-type bars. One n-type is connected to the emitter, while the other is connected to the collector. The p-type is connected to the base. The excess holes in p-type silicon operate as barriers, preventing current flow. Applying a positive voltage to the base and collector while negatively charging the emitter causes electrons to flow from the emitter to the collector.

In a PNP transistor, the arrangement and quantity of p-type and n-type blocks remain inverted. One n-type is sandwiched between two p-type blocks in this sort of transistor. A PNP transistor works differently than an NPN transistor because the voltage allocation is different. A positive voltage to the base is required for an NPN transistor, whereas a negative voltage is required for a PNP transistor. To turn a PNP transistor on, the current must flow away from the base.

C. Purpose and Importance

In most electronic circuits, transistors serve as both switches and amplifiers. A transistor is frequently used as a switch by designers because, unlike a basic switch, it can transform a little current into a much bigger one. Although a simple switch can be used in a simple circuit, an advanced circuit may require variable currents at different stages.

Hearing Aid Transistors

The hearing aid is one of the most well-known applications of transistors. The sound waves are usually picked up by a small microphone in the hearing aid, which is then converted into fluctuating electrical pulses or currents. These currents are magnified when they pass through a transistor. The amplified pulses are then sent through a speaker, where they are converted back into sound waves. As a result, you might hear a much louder version of the ambient sounds.

Computers and Calculators with Transistors

We all know that computers use the binary language of “zero” and “one” to store and process data. Most people are unaware, however, that transistors play a crucial part in the creation of logic gates, which are the backbones of computer programmes. Transistors are frequently used with logic gates to create a unique configuration known as a flip-flop. Even after the base current is removed from this setup, the transistor stays “on.” When new current passes through it, it now turns on or off. As a result, a transistor may hold a zero when it’s turned off or a one when it’s turned on, which is how computers work.

Darlington Transistors are a type of transistor.

Two PNP or NPN polar junction transistors are combined to form a Darlington transistor. It bears the name of its creator, Sidney Darlington. A Darlington transistor’s main purpose is to deliver a large current gain from a low base current. These transistors can be found in power regulators, display drivers, motor controllers, light and touch sensors, alarm systems, and audio amplifiers, among other instruments that require a high current gain at a low frequency.

MOSFET and IGBT Transistors

Insulated-Gate Bipolar Transistor (IGBT) transistors are commonly employed as amplifiers and switches in a wide range of devices, including electric cars, trains, refrigerators, air conditioners, and even stereo systems. Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs), on the other hand, are frequently employed in integrated circuits to manage a device’s power levels or to store data.


A resistor is a two-terminal passive electrical device that opposes current flow. It is most likely the most basic component in an electrical circuit. Resistance is present in practically all electronic circuits, making it one of the most prevalent components. Typically, they are color-coded.

A. Structure

Because resistance is a natural feature of practically all conductors, a resistor isn’t a complicated gadget at all. A capacitor is made out of a copper wire that is wrapped around an insulating material like a ceramic rod. The resistance is proportional to the number of turns and the thickness of copper wire. The resistance increases as the number of turns and wire thickness increase.

Resistors built of a spiral pattern of carbon film are also available. Carbon film resistors get their name from this. Carbon film resistors are not as exact as wire-wound competitors, thus they’re best for low-power circuits. They are, nonetheless, less expensive than connected resistors. Both ends of the wire are connected with wire terminals. The electricity can flow in either direction via resistors since they are blind to the polarity in a circuit. As a result, there’s no need to be concerned about whether they’re attached front or backward.

B. What Is It and How Does It Work?

A resistor may appear to be insignificant. It may appear like it does nothing but devour energy. It does, however, serve an important purpose: it regulates the voltage and current in your circuit. Resistors, in other terms, allow you control over the layout of your circuit.

When an electric current is applied to a wire, all of the electrons begin to move in the same direction. It’s the same as water running through a pipe. Because there is less room for water to go through a thin pipe, less water will flow through it.

When current travels through a small wire in a resistor, the electrons find it increasingly difficult to wiggle through it. In other words, as the length and thinness of the wire grows, the quantity of electrons flowing through the resistor decreases.

C. Purpose and Importance

The three most typical applications for resistors are regulating current flow, splitting voltage, and resistor-capacitor networks.

Controlling Current Flow

Current will flow at dangerously high levels if resistors are not added to a circuit. It has the potential to overheat and damage other components. An LED, for example, might be connected directly to a battery and still function. However, after a while, the LED will become as hot as a fireball. Because LEDs are less heat tolerant, it will eventually burn.

However, if you add a resistor to the circuit, the current flow will be reduced to an optimal amount. As a result, you can leave the LED on for longer without it overheating.

Voltage Division

To lower the voltage to the required level, resistors are also utilised. A specific component in a circuit, such as a microcontroller, may require a lower voltage than the circuit as a whole. A resistor is used in this situation.

Assume your circuit is powered by a 12V battery. The microcontroller, on the other hand, simply requires a 6V supply. To divide the voltage in half, simply connect two resistors with the same resistance value in series. The cable connecting the two resistors has cut the voltage of the circuit where the microcontroller can be connected in half. You can lower the voltage in the circuit to any level by using appropriate resistors.

Networks of Resistor-Capacitor

Resistors and capacitors are also used together to make ICs with resistor-capacitor arrays on a single chip. RC filters and RC networks are other names for them. They are frequently used to suppress electromagnetic interference (EMI) or radio frequency interference (RFI) in a variety of instruments, including computer and laptop input/output ports, LANs, and WANs, among others. Machine tools, switchgears, motor controllers, automated equipment, industrial appliances, elevators, and escalators are all places where they’re utilised.

Nowadays, we might know that new electronics will cost us a lot of money if we buy them directly from the shopkeeper. So how to buy electronics at lower prices? As far as I’m concerned, one good way is to buy wholesale electronics, because it will benefit us a lot. And you need to realize that you are asked to do many things if you want to buy wholesale e Cigarettes successfully.

Attend the Local Trade Shows

Nowadays, we might know that new electronics will cost us a lot of money if we buy them directly from the shopkeeper. So how to buy electronics at lower prices? As far as I’m concerned, one good way is to buy wholesale electronics, because it will benefit us a lot. And you need to realize that you are asked to do many things if you want to buy wholesale e Cigarettes successfully. If you don’t know, don’t worry, because I’ll spend some ideas on how to buy wholesale electronics. So if you are a person who wants to buy electronics, you are asked to take the time to read this article.

But it might not be easy to find a reliable wholesaler, for many Distributors might sell counterfeit electronics. So it is necessary for you to check whether the distributor is reliable enough or whether they are e Cigarettes that are of good quality. And that might play an important role in the success of your business.

If you want to buy wholesale electronics from a trusted distributor, so you are asked to gather some information about wholesalers, such as whether their reputation is safe or not and how efficient their productivity is. You need to remember not to accept orders for your electronics unless you have checked that your wholesaler found a trustful. Apart from that, you can also ask a friend or someone who has experience buying wholesale e Cigarettes gives you some useful information about wholesaling. So, you might have the possibility to find a reliable wholesaler through this method.

Use Yellow Pages

You are also asked to do the following even though you have found a reliable distributor. For one thing, you can ask him to provide an electronic sample so you can check whether the quality of the electronics is good. For other things, you are asked to sign a contract with a wholesaler. And the reason is that once there are several disputes after a great agreement, you can resolve this dispute according to the contract. So many details need to be included in the contract, such as delivery date, insurance, wholesale number of cigarettes and joint responsibility and so on.

All in all, you need to pay attention to many details when you are going to buy wholesale electronics. Suppose you have found a dishonest wholesaler and made a deal with him, then you will regret it after you have received poor quality electronics. However, there was no use of crying at that time because colossal losses had been caused. What’s worse, you might face damage to your business after you have been cheated by dishonest wholesalers. So it is very necessary for you to find a good wholesaler if you want to make profit through wholesale products.

Many security-related systems that will use electromechanical technology or Solid-State electronics now use programmable electronics.

IEC 61508 covers functional safety of safety-related systems using programmable electronic and / or electronic (E / E / PE) technology. This standard applies to this system regardless of their application.
Examples of systems related to E / E / PE safety using electrical (or electro-mechanical) technology are interlocking guards and emergency stop systems for machines.

Functional safety

Devices such as programmable controllers, programmable logic controllers (PLCs) and digital communication systems (eg bus systems) are part of this trend.

Examples of applications include safe load indicator cranes, variable speed drive motors used to limit speed for protection, systems for interlocking and controlling the exposure dose of medical radiotherapy machines, or indicator lights, anti-lock braking, and engine management systems in cars. Other examples are emergency shutdown systems at hazardous chemical plants, railroad signaling systems and Fly-bywire operations. Surface flight control aircraft are the latest developments including network-based security systems, often facilitated by internet technology.

An exampleis Remote Monitoring, operating or programming from a network-enabled water treatment plant. E / E / PE safety related systems cover all parts of the system needed to carry out safety functions (ie from sensors, through logic control and communication systems, to final actuators, including critical actions from human operators). An E / E / PE system may be related to safety even if it does not have direct control over potentially dangerous equipment. For example, information-based decision support tools might be related to safety if erroneous results affect safety.

IEC 61508 as a basis for other standards Sections 1, 2, 3 and 4 of IEC 61508 are IEC’s basic safety publications. One of the responsibilities of the IEC technical committee is, wherever practical, to utilize this part of IEC 61508 while preparing their own sector or product standards that have E / E / PE related to safety systems within their scope.

Electronic Systems and Electronic Control Systems

For more details see IEC Guide 104, the preparation of safety publications and the use of basic safety publications and group security publications and ISO / IEC 51 guidelines, the safety aspects of the guidelines for their inclusion in the standard. IEC 61508 is the basis for published nuclear sector standards. It is also currently being used as a basis for developing other sector standards (for example machinery, processes) and Product standards (for example the propulsion system). Therefore it affects the development of E / E / PE related to the safety of systems and products in all sectors.

Many IEC 61508 requirements, especially in sections 2 and 3, are not repeated in the application sector or product standard but are referenced instead. The result is that most users will need IEC 61508 too.
The market for each product, component, or subsystem that complies with IEC 61508 has huge potential because in principle they are able to meet the sector standard requirements based on IEC 61508.

This article explains what you need an electronics manufacturing service provider from you to prepare an accurate quote for a typical printed circuit board assembly project.

Electronic Manufacturing Services

Electronic contract manufacturing services or EMS providers usually work with customers in various industries with different requirements for inventory control, testing, product packaging, and product support. In some applications, EMS providers only assemble printed circuit boards and then ship the boards to customers. Some customers will provide all materials, raw boards and electronic components, required for the work and EMS provider of printed circuit board assemblies, carry out any necessary testing, and ship the finished boards to the customer. This is generally considered as supplies provided on a consignment basis where EMS providers basically provide labor and expertise only.And rely on the EMS provider to purchase the remaining components needed to assemble the board. Most EMS providers prefer to use their own purchasing power, their extensive contacts, and existing inventory sections where applicable to provide all materials needed for a customer’s particular project. This method is generally considered to be an inventory that is provided on a Turn-Key basis.

But before this can happen, the EMS provider must provide customer assembled board quotes or price estimates for the project. In addition to the quantity commitment, the quantity of production release and the quantity of annual usage, this pricing process also requires a detailed bill of materials from the customer along with a set of Gerber files for printed circuit boards. BOM must determine all components with an approved vendor and vendor component numbers for each component. BOM information is also needed to enable technical reviews to determine the amount of labor and equipment needed to place parts and to solder components to the board.

What Does an Electronic Manufacturing Services Company Do?

Gerber files for printed circuit board design provide material Management with the information they need to get raw board prices and Lead Times from Printed Circuit Board manufacturing vendors. The Gerber file also provides the manufacturing group with the information they need to develop a manufacturing plan, the components are above only or above and below the board; surface mount, through holes, or mixed type components; wave soldering or reflow oven processes are needed, etc. In order to correctly place components on a printed circuit board with each component correctly oriented, the EMS provider will need a silkscreen file to find out the correct orientation of the parts on each side of the board. A screen paste file for surface mount applications will be required to order stencils for solder paste applications to the board prior to section placement.

All of this might seem like a lot of information, but every part is needed in order to provide the most cost effective for the finished product. Fortunately, Gerber files are usually available from PCB design systems because the Gerber format is the industry standard output format. BOM is usually in the form of an Excel spreadsheet or formal image. Assist your EMS provider by providing an approved vendor name and part number for each component.
