All-round analysis of electronic components knowledge

　　Electronic components are the basic components of electronic circuits, which are used to control, transmit and process electronic signals. According to different functions, electronic components can be divided into active and passive components.So we can draw a preliminary conclusion, electronic parts store It is helpful to the needs of the industry market and social development. https://www.asourcingelectronics.com/

　　

　　Second, the classification of electronic components

　　

　　Active component

　　

　　Active components can provide amplification, oscillation or conversion functions, and usually rely on external power supply for operation.

　　

　　Diode: allows current to flow in one direction, and is usually used for rectification (converting alternating current into direct current).

　　

　　Type: rectifier diode, zener diode, Schottky diode, etc.

　　

　　Triode: used for signal amplification and switch control.

　　

　　Type: bipolar (BJT) and field effect (FET) transistors.

　　

　　Operational amplifier (Op-Amp): Used for analog signal processing, which can be used for amplification, addition and integral calculation. Commonly used in audio processing, sensor signal conditioning and other applications.

　　

　　Integrated circuit (IC): integrating multiple functional circuits on one chip, which can be divided into digital and analog IC.

　　

　　passive components

　　

　　Passive components can not provide amplification or conversion functions, but passively respond to input signals.

　　

　　Resistance (R): Restrict current flow and control voltage distribution. The unit is ohm (ω).

　　

　　Capacitor (C): It stores and releases electric energy, and is usually used for coupling, decoupling and filtering. The unit is Farah (f).

　　

　　Inductance (L): A magnetic field that stores energy, usually used for filtering and oscillators. The unit is Henry (h).

　　

　　Transformer: used to change the voltage level (step-up or step-down) in AC current.
