What is an inductor and how to name the inductor?

l  What is an inductor? What's the role?

An inductor is an energy storage element that converts electrical energy into magnetic energy and converts it into electrical energy. When the alternating current passes through the coil, an alternating magnetic field is generated around the coil, causing the coil itself to generate an induced electromotive force. This kind of induction phenomenon is called self-inductance phenomenon, and the electromotive force generated by it is called self-induction electromotive force, the size of which is proportional to the rate of change of current. The self-induced electromotive force is always trying to prevent the current from changing in the circuit. The inductor has the characteristics of low frequency, high and DC resistance, which can store electrical energy in an ideal state. It can be used in conjunction with the capacitor to form an adjuster filter, which plays the role of frequency selection and division. The magnetic field will be generated around the inductance coil after electrifying, and it can be used to form electromagnet, relay and so on. The combination of the alternating current coil and the permanent magnet can form a loudspeaker, so that the coil moves in the magnetic field of the permanent magnet ( cutting the magnetic force line ), alternating current can be generated in the line diagram, which can be made into a microphone, and alternating current is generated in the coil, and alternating magnetic field will be generated around the coil, in an alternating magnetic field, both ends of the online country will constantly generate induced electromotive force, and use this characteristic, the coil can be wound around the core into a transformer.

l  How to name the inductor?

Inductors can be divided into two categories: inductance coils and mutual inductance transformers.

The inductor has the most standard designation of the fixed inductor, and the middle frequency transformer and the power transformer are used in the transformer.

The name is most standardized, and the rest of the inductors are named by enterprises themselves.

LG1 type.LG2 is the most common type of fixed inductor. The LG1 type fixed inductor is an axial lead, that is

The two leads are at the ends of the inductor: the LG2 type fixed inductor is the same lead, that is, the two leads are inductors.

At the same end. The maximum working current of the fixed inductor can be expressed in English letters.
