chengzhong Microelectronics professional Anshi/Nexperia distributor, we will update the relevant information about the electronic components industry and products from time to time, and look forward to your attention!
Today I will mainly talk to you about the main detailed classification of electronic components
1. Component refers to a product that does not change the molecular composition of raw materials during processing. Components can be called components. Components are devices that do not require external energy. It includes: resistor, capacitor, inductor. (Also known as passive components Passive Components)
Electronic Components
Components are divided into:
1, circuit components: diodes, resistors , etc.
2, connection components: connectors, sockets, connection cables, printed circuit boards (PCBs)
2. Device refers to a product that changes the molecular structure of raw materials during production and processing in the factory. It is called device
1, active devices. Its main characteristics are: (1) It consumes power itself (2) It requires external power.
2, discrete devices, divided into (1) bipolar crystal transistor (2) field effect transistor (3) silicon controlled (4) Semiconductor resistance capacitor
resistor
resistor
resistor is represented by "R" and numbers in the circuit, such as: R1 represents a resistor numbered 1. The main functions of resistors in the circuit are: shunt, current limiting, voltage division, bias, etc.
capacitor
capacitor is generally represented by "C" and numbers in the circuit (such as C13 represents a capacitor numbered 13). The capacitor is made of two pieces of metal The film is close to the element and is separated by insulating materials in the middle. The characteristics of the capacitor are mainly DC-separated AC. The capacity of the capacitor indicates the size of the energy that can be stored. The hindering effect of the capacitor on AC signals is called capacitance , which is related to the frequency and capacity of the AC signal.
crystal diode
crystal diode is commonly used in circuits with "D" plus numbers, such as: D5 represents a diode numbered 5.
Function: The main characteristic of a diode is unidirectional conductivity, that is, under the action of the forward voltage, the on-resistance is very small; while under the action of the reverse voltage, the on-resistance is extremely large or infinite.
Because diodes have the above characteristics, it is often used in circuits such as rectification, isolation, voltage regulation, polarity protection, encoding control, frequency modulation and noise squeezing.
Inductors
Inductors are not used many times in electronic production, but they are equally important in circuits. We believe that inductors, like capacitors, are also energy storage elements that can convert electrical energy into magnetic field energy and store energy in the magnetic field. The inductor is represented by the symbol L, and its basic unit is Henry (H), which is commonly used as the unit of milliheng (mH). It often works with capacitors to form LC filters, LC oscillators, etc. In addition, people also use the characteristics of inductor to create current blocking coils, transformers, relays, etc.
Electronic Components
Combination Circuit
Integrated Circuit is a device with certain functions formed by integrating transistor , resistor, capacitor and other components on a silicon substrate using a special process. It is abbreviated as IC, also commonly known as chip.
Analog integrated circuit refers to an analog integrated circuit that is integrated with capacitors, resistors, transistors and other components to process analog signals. There are many analog integrated circuits, such as integrated operational amplifier , comparator , logarithmic and exponential amplifier, analog multiplication (divider) analog, phase-locked loop , power management chip , etc. The main components of analog integrated circuits are: amplifiers, filters, feedback circuits, , reference source circuits, switching capacitor circuits, etc. Analog integrated circuit design is mainly obtained through manual circuit debugging and simulation by experienced designers. Most of the corresponding digital integrated circuit design is automatically generated by using hardware description language under the control of EDA software.
digital integrated circuit is an digital logic circuit or system made by integrating components and connections on the same semiconductor chip.According to the number of gate circuits, or components contained in the digital integrated circuit, digital integrated circuits can be divided into small-scale integrated (SSI) circuits, medium-scale integrated (MSI) circuits, large-scale integrated (LSI) circuits, ultra-large-scale integrated VLSI circuits and ultra-large-scale integrated ULSI) circuits. Small-scale integrated circuits include less than 10 gate circuits, or the number of components does not exceed 100; medium-scale integrated circuits include between 10-100 gate circuits, or the number of components is between 100-1000; large-scale integrated circuits include more than 100 gate circuits, or the number of components is between 10-10; ultra-large-scale integrated circuits include more than 10,000 gate circuits, or the number of components is between 10-10; super-large-scale integrated circuits include more than 10,000 gate circuits, or the number of components is between 10-10; super-large-scale integrated circuits include between 10-10. It includes: basic logic gate , trigger, register, decoder , driver, counter, shaping circuit, programmable logic devices, microprocessor, microcontroller , DSP, etc.
