3、 Inductor

An inductor is a device capable of storing electromagnetic energy, consisting of a coil and a magnetic core. The main function of an inductor is to filter, stabilize, transform, and regulate signals, and it is commonly used in various electronic devices. diode,

1. Filtering function

Inductors can filter current through their impedance characteristics, removing unwanted signals such as high-frequency noise and clutter, thereby improving the signal-to-noise ratio of the system. The filtering function of inductors is commonly used in various power supplies, amplifiers, filters, and other circuits.diode

2. Voltage stabilizing effect

Inductors can also be used as voltage regulators to control voltage fluctuations in circuits through their inductance characteristics, thereby achieving stable control of output voltage. Inductor voltage regulators are commonly used in various high-precision circuits, RF circuits, and other fields. diode

3. Voltage transformation effect

Inductors can achieve voltage transformation by changing the number of turns of the coil, the material of the magnetic core, etc., converting input voltage into output voltage. The voltage transformation function of inductors is commonly used in various power supplies, amplifiers, frequency converters, and other circuits. diode
