Inductor main parameters

The inductance is also called the self-inductance coefficient, which is a physical quantity indicating that the inductor generates self-inductance.

The amount of inductance of the inductor depends mainly on the number of turns of the coil (number of turns), the winding method, the presence or absence of the core and the core material. Generally, the more coil turns, the denser the wound coil, and the greater the inductance. A coil with a core has a larger inductance than a coil without a core; a coil with a larger magnetic permeability has a larger inductance.

The basic unit of inductance is Henry (referred to as Henry), which is represented by the letter "H". Commonly used units are millihenry (mH) and microhenry (μH). The relationship between them is:

1H=1000mH 1mH=1000μH
