Electronic components are electronic components and small parts of machines and instruments, which themselves often consist of a number of parts, can be common in similar products; often refers to electrical appliances, radio, instrumentation and other industrial parts, capacitors, transistors, hairspring, clockwork, and other electronic devices, the general term. common components on a PCBA
Electronic components are composed of two major components: electronic devices and electronic components.
(1) Electronic devices
Refers to finished products that do not change the molecular composition during factory production and processing. Such as resistors, capacitors, inductors. Because it does not produce electrons itself, it has no control and transformation of voltage and current, so it is also known as passive devices.
(2) Electronic components
Refers to the factory production and processing to change the molecular structure of the finished product. For example, transistors, tubes, integrated circuits. Because it can produce its own electrons, the voltage, current control, transformation (amplification, switching, rectification, detection, oscillation and modulation, etc.), so also known as active devices. According to the classification standards, electronic devices can be divided into 12 major categories, which can be summarized into two blocks of vacuum electronic devices and semiconductor devices.
Electronic components have the quality of international CE certification in the European Union, the United States UL certification, Germany's VDE and TUV certification and China's CQC certification and other domestic and international certifications to ensure that the components are qualified.
Electronic components include: resistors, capacitors, inductors, potentiometers, tubes, heat sinks, electromechanical components, connectors, semiconductor discrete devices, electro-acoustic devices, laser devices, electronic display devices, photovoltaic devices, sensors, power supplies, switches, microtronics, electronic transformers, relays, printed circuit boards, integrated circuits, various types of circuits, piezoelectricity, crystals, quartz, ceramics and magnetic materials, printed circuits with substrate, electronic functional process special materials, electronic adhesive (tape) products, electronic chemical materials and parts.
What are the common components on a PCBA board?
Commonly used electronic components are: resistors, capacitors, inductors, potentiometers, transformers, diodes, transistors, MOS tubes, integrated circuits and so on.
(1) IC
IC is a kind of miniature electronic device or part, plays a role in reducing the use of components and improving the performance of the product.
(2) Resistance
The resistance of a conductor to current is called the resistance of the conductor. It is expressed by the symbol R, and the units are ohms, kilo-ohms, and megohms, which are expressed as Ω, KΩ, and MΩ, respectively.
(3) Capacitance
Indicates that the capacitor charge capacity of the physical quantity, is electronic, electric power in the field of indispensable electronic components. Mainly used in power supply filtering, signal filtering, signal coupling, resonance, DC and other circuits, capacitance symbol is C.
(4) Inductance
Inductors are components that can convert electrical energy into magnetic energy and store it, only preventing the change of current.
(5) Transformer
A transformer is a device that utilizes the principle of electromagnetic induction to change the AC voltage. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer) and so on. Transformers are commonly used for voltage, matching impedance, safety isolation.
(6) diode, transistor
A diode is a device with two electrodes, which only allows the current to flow in a single direction of the electronic components. A triode is a current control current semiconductor device, its role is to amplify the weak signal into a larger spoke value of the electrical signal, also used as a non-contact switch, crystal transistor, is one of the basic semiconductor components, with the role of current amplification, electronic circuits are the core components.
(7) MOSFET
MOSFETs are often used in amplification circuits or switching circuits. The basic principle of operation is to use the gate-source voltage to control the drain current.
