Inductance Features And Applications

inductor is an element that can store electrical energy into magnetic energy and store it. The structure of the inductor is similar to a transformer, but with only one winding. The inductor has a certain inductance that only blocks the change in current. If the inductor is in a state where no current is flowing, it will attempt to block current flow through it when the circuit is turned on; if the inductor is in a state where current is flowing, it will attempt to maintain the current when the circuit is turned off. Inductors are also known as chokes, reactors, and dynamic reactors.

The inductor is generally composed of a skeleton, a winding, a shield, a packaging material, a core or a core.

Inductors can be divided into: adjustable inductors, choke inductors, differential mode inductors, common mode inductors, power inductors, magnetic bead inductors, I-shaped inductors, laminated inductors, high frequency inductors, RF inductors, shielded inductors, winding Line inductance, color ring inductance, magnetic core inductance, three-pin inductance, high current manganese-zinc inductance, iron-silicon-aluminum magnetic ring inductance, chip inductor, plug-in inductor, horizontal inductor, rod inductor,

The inductor mainly plays the role of filtering, oscillation, delay, trapping, etc. in the circuit, as well as screening signals, filtering noise, stabilizing current and suppressing electromagnetic interference. The most common function of the inductor in the circuit is to form an LC filter circuit together with the capacitor. The capacitor has the characteristics of “resistance to DC, AC”, while the inductor has the function of “DC, DC”. If the DC current with many interference signals is passed through the LC filter circuit, the AC interference signal will be consumed by the inductor into heat energy; when the relatively pure DC current passes through the inductor, the AC interference signal is also turned into a magnetic sense. And thermal energy, the higher the frequency is the most easily inductive impedance, which can suppress higher frequency interference signals.
The inductor has the characteristic of preventing the passage of the alternating current and allowing the direct current to pass smoothly. The higher the frequency, the larger the impedance of the coil. Therefore, the main function of the inductor is to isolate, filter or form a resonant circuit with a capacitor or a resistor.
