There are many basic electronic components used to build electronic circuits. Without these components, the circuit design is never ready or has not worked properly. These components include resistors, diodes, capacitors, integrated circuits and so on. Some of these components consist of two or more connectors glued to the circuit boards. Some may be packaged types, such as integrated circuits that contain different semiconductors. Here is a brief overview of each of these basic electronic components and you can get detailed information by clicking on the links for each component.

Basic electronic components

Electronic components are separate basic units for use in any electronic electronics system that has different domains. These components are the basic elements used for the design of electrical and electronic circuits. These components have at least two connectors used to connect the circuit. The classification of electronic components can be done, for example, on the basis of active, passive and electromechanical applications.

The most important electronic components

The design of the electronic circuit takes into account the following:

Basic electronic components: capacitors, resistors, diodes, transistors, etc.
Power supplies: Signal generators and direct current sources.
Measurement and analysis equipment: cathode ray oscilloscope (CRO), multimeters, etc.

Active components

These components are used to amplify electrical signals to produce electricity. The operation of these components can be done as an electrical circuit in the electrical equipment to protect the voltage and current. The active component performs its function because it is controlled by a power supply. All of these components require a power source, which is usually removed from the DC circuit. All high quality active components include an oscillator, an IC (integrated circuit) and a transistor.

Passive components

Components of this type cannot use the power supply of an electronic circuit because they do not depend on a power supply, except for those available in the AC circuit to which they are connected. As a result, they cannot amplify even if they can increase the current, otherwise the voltage or current. These components mainly include bidirectional connectors, such as resistors, inductors, transformers and capacitors.

Electromechanical components

These components use an electrical signal to make some mechanical changes, such as rotating the motor. Typically, these components use an electric current to generate a magnetic field so that physical movement can occur. Different types of switches and relays can be used in this type of components. Devices that have both an electrical process and a mechanical process are electromechanical devices. The electromechanical component is used manually to produce electricity by mechanical movement.

Passive electronic components

These components can store or maintain energy in the form of current or voltage. Some of these components are discussed below.


A resistor is a bipolar passive electronic component used to resist or limit current. The resistor operates according to the principle of Ohm’s law, where “the voltage applied to the terminals of the resistor is directly proportional to the current flowing through it”


An electronic circuit is a structure that controls and directs electric current to perform a variety of functions, including signal amplification, calculation, and data transmission. It consists of several different components, such as resistors, transistors, capacitors, inductors and diodes.

Electronics and Casino Game Use – What You Need to Know

In the casino and electronics world there are two types of people that you would be most likely to see walking around, one of these being the electronics store owner. For the owner of a electronics store in Las Vegas or Atlantic City this can be very exciting news indeed, after all, they have a great deal of inventory available for their customers to purchase. They can also serve as a liaison between the players and the games, assisting them with their needs and assisting them in finding what they need quickly so they do not have to take their items home with them. This is a business that requires a great deal of patience and knowledge so that the players can find the electronics that they need without having to leave the games.

When shopping at the electronics store in Las Vegas or Atlantic City it is important to remember that you are dealing with electronics shops and not brick and mortar businesses, so you are not purchasing actual merchandise; rather, you will be purchasing credit card information, which will then be used to make purchases until you either pay for your purchase using that credit card or leave the electronics shop. Because all purchases are done with credit cards you need to be very careful about spending too much money, because when you do so you will incur costly late fees. It is important that before you use your credit card to make a purchase at an electronics shop that you read all of the fine print associated with such purchases.

You should also keep in mind that the vast majority of electronics stores in Las Vegas and Atlantic City have online websites. These websites will generally list prices for the products that they sell as well as provide a link to the casino where the product can be purchased. You will want to make sure that when you are actually in the store that you are indeed buying electronics for the gaming table and not some other merchandise. There are many different types of gambling at both of these locations, so you should do some homework as to which games you prefer to play before visiting the electronics store. Either way, Las Vegas and Atlantic City have made shopping for electronics and casino equipment easier for many people, so you should definitely check them out while you are there.


Basic electronic components, the operation of which depends on an external power supply, are called active components. They can amplify signals and / or process signals. Some active components are transistors, integrated circuits.


A transistor is a nonlinear semiconductor. The transistor is considered one of the most important devices in electronics. The transistor has changed many aspects of human life. Transistors have two main functions, which amplify the input signals and act as semiconductor switches. The transistor acts as a switch when used in the saturation or interruption interval. Amplifies signals when used in the active area. It offers a very high input resistance and a very low output resistance.

Transistors are classified according to the structure of bipolar transverse transistors and field effect transistors.

Transistor symbol

The most popular and commonly used transistors are BC547, 2N2222. Below are some common transistor packages:

A metal oxide semiconductor field effect transistor (MOSFET) is a semiconductor device that differs in structure from a bipolar junction transistor, although the applications are the same as coupling and amplification. It has four terminals such as Drain, Gate, Source and Body. The chassis is short-circuited to the source socket. The gate is insulated from the pipe next to a very thin layer of metal oxide. Therefore, it offers a very high durability compared to BJT.

By checking the gate voltage (VGS + ve / -ve) of the channel along which the charge carriers (electrons or holes) flow from the source to the channel, the width can be checked. P-channel MOSFET has a P-channel area between the source and channel, and N-channel MOSFET has an N-channel area.

The advantages of MOSFET over BJT

  • Very high resistance to entry
  • Reduced opposition to the state
  • Reduced energy losses
  • High operating frequency
  • Transistor operation
  • Transistor operation
  • Use of transistors (BJT / FET)

Amplification of analog signals.

Used as replacement units in SMPS, microcontrollers, etc.
Overvoltage / undervoltage protection
signal modulation and demodulation circuits.
Current control in converters and chargers (high power transistors)
Types of transistor packages

For BJT and MOSFET packaging, the transistors are available in orifice (DIP) and SMD versions. for example, DIP: TO-92, TO-220 and SMD: SOT23, SOT223, TO-252, D2PAK.

Transistor selection parameters

When selecting a transistor in any user of the circuit, consider the following parameters

  • Maximum collection current (Ic)
  • Maximum collector voltage (Vce)
  • VBE voltage
  • Saturation Vce (village) tension
  • Current gain, hfe / ß
  • Input resistor
  • The first answer
  • Reverse distribution voltage
  • Maximum return current.
  • Evaporation of force
  • Interface temperature
  • size
  • Switching time / frequency

Integrated circuits

An integrated circuit (IC) is an electronic circuit embedded in a semiconductor board, which is usually silicon. This disk has millions of compact transistors, resistors and capacitors connected to metal strips. ICs are powered by an external power supply for operation. ICs perform certain functions, such as data processing and signal processing. The physical size of an IC disk is very small compared to discrete circuits, so it is called a microchip or just a chip. Due to its small size, the IC has low power consumption.


The various consumer electronics expos held in the United States are some of the biggest technological events every year, hosting hundreds of trade shows displaying rentals in one building. Learn more about the history of these events and what they bring every year.

Consumer electronics expos are often some of the biggest and most important events in the world of technology. Once a year various organizations bring together electronics companies from all over the world to showcase their work. For those involved in the technology industry, this event was held in high regard because many major announcements of new products were made to them. Most businesses display their yet-to-be released products, not what is currently on the market. For anyone involved in the industry, Electronic Expos should not be missed.

Consumer Electronics Show

The first of these exhibitions was held in the late 1960s. The amalgam of screen rental trade shows is a smashing success, and soon the electronic Expos is rooted in different cities around the world. Part of the allure of this event is due to the announcement of breakthrough new products by major players in the industry. The announcement of a new video game system, media type, and television format has brought great media attention to this event, so companies are competing to bring the most exciting new products that are taking the spotlight. Due to the increasing presence over the years, most of the Expos are no longer open to the public. Participants usually must first register with the organization and prove that they are involved in the industry.

The exposures themselves have evolved from their humble beginnings. Trade shows display rentals that are intricately and stunningly designed. Stands are packed with Gizmos and gadgets for participants to interact with and the smartest and most interesting staff employees in their best form. An electronic exhibition is an opportunity for technology companies to put their best foot forward for the press, so there are no costs that are prohibited when considering a presentation.

Electronic Tech Expo USA

Electronic Expos is much more than just a rental bundle displaying trade shows on the main floor, however. Companies and individuals give presentations and announcements throughout the event, and many areas are available for this to happen. For each day of the event, the main speakers are usually invited to talk about issues related to the industry. Individual companies also rent out large Ballrooms to host the opening of their newest products. Panels from several guests from various fields provide more open discussion of technology, and some companies even have smaller meeting rooms for more intimate conversations with their visitors away from the main floor.

Even if you are unable to attend, the week leading to Expos electronics is full of speculation and excitement as the world of technology prepares to uncover the next step in innovation. Thanks to technology that was partly inspired by the event itself, members of the general public can now see much coverage from online events. The video from the demo on the showroom floor made them feel as if they were right between the rental trade show display and the rest of the press. Apart from that, it’s only a matter of time before a new gadget will be available for everyone to use!

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.
