What are the classifications of electronic components?

What are the classifications of electronic components? Electronic components are the foundation of all electronic products. Both electronic engineers and electronic design enthusiasts must have an in-depth understanding of electronic components. This article first introduces the classification and function of electronic components. With the development of science and technology, the types of electronic components are increasing, with approximately 10,000 types. According to the different functions in the circuit, common electronic components can be roughly divided into 17 categories and 56 series. These 17 categories include: 1. Resistors: Resistors, potentiometers; 2. Capacitors; 3. Inductors; 4. Transformers; 5. Relays; 6. Integrated Circuits: Voltage regulators (three-terminal voltage regulators, five-terminal voltage regulators, fixed voltage regulators, adjustable voltage regulators, switching integrated voltage regulators), converters, operational amplifiers, thick-film circuits (power thick-film circuits, power amplifier thick-film circuits), digital circuits (integrated circuits, integrated circuits), conversion circuits, music circuits, language circuits, special-purpose circuits (TV integrated circuits, remote control integrated circuits, audio integrated circuits, player integrated circuits), 555 timer circuits. 7. Diodes: Ordinary diodes (rectifier and detector diodes), unijunction transistors, special diodes (bidirectional trigger diodes, fast recovery diodes, varactor diodes,

What is the function of electronic components? With the development of science and technology, the types of electronic components are increasing, with approximately 10000 types. According to the different functions in the circuit, commonly used electronic components can be roughly divided into 17 categories and 56 series. Any electronic device or electronic equipment is composed of electronic components, which play different roles in the circuit and work together to complete specific "tasks". In short, electronic components play ten major roles in the circuit. 1. Voltage exchange Here, voltage exchange has three meanings. First, high and low voltage conversion. Converting AC or DC high voltage to the required low voltage, or converting AC or DC low voltage to the required high voltage. Usually, the conversion of high and low AC voltage requires a transformer, while the conversion of high and low DC voltage requires complex electronic circuits. Another is AC and DC conversion, that is, the DC voltage required by the circuit (referred to as the circuit) is converted from the 220V mains power through rectification and filtering, or the DC voltage is converted into AC voltage through an inverter, for example, in car repair, the DC 12V of the battery is converted into AC 220V. The third is voltage stabilization. Voltage regulators or voltage stabilizing circuits are used to change unstable DC or AC voltage into a very stable voltage. The former is called

What are the functions of electronic components?

What are the functions of electronic components? As an embedded system, I don't know how to master circuits, but at least we should understand circuits and their functions. Here is a summary of the functions of some electronic components, hoping to be helpful to you. 1. Resistor: Resistors are mainly used to adjust and stabilize the current and voltage in the circuit. It can be used as a shunt and voltage divider, and can also be used as a load matching the circuit. According to circuit requirements, it can also be used for negative feedback or positive feedback when the amplifier circuit input is overloaded, voltage current conversion, voltage or current protection components, and can also form RC circuits such as oscillation, filtering, bypass, differential, integral, and time constant components. 2. Capacitor: Generally used for filtering. The smaller the capacitance, the higher the filtering frequency. Usually 103104 capacitors are used. 104 capacitors are used in the projects I do. In the Xintang chip, manual jitter elimination is not required. The effect is very good. 3. Transistor: This is a commonly used component. In digital circuits, it is usually used for switching functions. The on and off characteristics of transistors are used to switch circuits. The digital tubes used in the author's project use transistors to control the switching of the digital tubes. If the I/O port of the chip is directly used to output high and low to control the digital tube, then when the output is low, the current will be very large, and for a long time

Electronic component manufacturer: Soldering matters and specific steps for integrated circuits (ICs)

Electronic component manufacturer: Preparation work for soldering integrated circuits ICs. Integrated circuits ICs have many and dense pins; small integrated circuits have dozens to hundreds of pins, making soldering difficult. Therefore, the following preparations must be made before soldering. Let's learn about the soldering matters and specific steps of integrated circuits ICs. I. Electronic component manufacturer: Preparation work for soldering integrated circuits ICs: 1. Soldering tools When using a soldering iron with a power of about 25W, the front end of the soldering iron should be pointed. Use an oil gun to trim the front end to avoid the burrs of the pointed tip dragging the leads during soldering. 2. Electronic component manufacturer: Soldering materials The main soldering materials are rosin, solder wire, solder paste, thinner, pure alcohol, etc. Low-melting-point solder wire must be used. 3. Cleaning the printed circuit board Before soldering, use a cloth to flatten the printed circuit board, and use a small brush to apply thinner to clean the area to be soldered on the printed circuit board. Carefully check the printed circuit board for peeling or debris. If there is peeling, just flatten it. However, if it is broken, it needs to be connected with a thin copper wire. 4. Electronic component manufacturer: Tinning the leads New integrated circuits have tin attached to the leads when they leave the factory and do not require any processing. Used ICs

How to accurately determine whether an integrated circuit (IC) is working in a circuit

Electronic component manufacturer: Correctly judging whether the integrated circuit IC in the circuit is working is an important part of repairing television, audio, and video equipment. If it cannot be judged, it is often difficult to replace the new integrated circuit, and the fault still exists. It is necessary to correctly judge the integrated circuit. So let's learn how to accurately judge whether the integrated circuit IC in the circuit is working! Electronic component manufacturer: How to accurately judge whether the integrated circuit IC in the circuit is working: 1. First, master the purpose, internal structure principle, and main electrical characteristics of the integrated circuit in the circuit. If necessary, analyze the internal electrical schematic diagram. In addition, if the DC voltage, waveform, and positive and negative DC resistance to ground of each terminal are known, it will provide more favorable conditions for pre-inspection judgment. 2. Then, judge the location based on the fault phenomenon, and find the faulty component based on the location. Several judgment methods may be needed to prove whether this device is indeed damaged. 3. Generally speaking, there are two methods for checking and judging the IC in the circuit. One is offline judgment, which means that the IC in the circuit is not soldered on the printed circuit board. This method is difficult to judge the quality of the IC without special equipment. Generally, the DC resistance method is used to measure the grounding pins of each pin.

Introduction to the Classification of Integrated Circuits (ICs) - A Must-Have Collection!

What are the classifications of integrated circuits (ICs)? Let's analyze them together. 1. According to the differences in function and structure, integrated circuits can be divided into analog integrated circuits, digital integrated circuits, and mixed analog/digital integrated circuits. Analog integrated circuits, also known as linear circuits, are used to amplify and process various analog signals (signals whose amplitude changes continuously over time, such as audio signals from a radio and signals from a tape recorder). The input and output signals are proportionally related. They can be used to integrate and process various signals (signals that are discrete in time and amplitude, such as reproduced audio and video signals). 2. According to the level of integration, integrated circuits can be divided into small-scale, medium-scale, large-scale, and very-large-scale integrated circuits. 3. According to the manufacturing process, integrated circuits can be divided into monolithic integrated circuits, thin-film integrated circuits, and hybrid integrated circuits. 4. According to the conduction type, they can be divided into bipolar circuits and unipolar circuits. Bipolar ICs have good frequency characteristics but high power consumption and complex manufacturing processes. Unipolar circuits have low operating speed, but high input impedance, low power consumption, simple manufacturing process, and are easy to integrate on a large scale. Most are...
