Inductance definition
Inductance is a property of the closed loop, that is, when the current passing through the closed loop changes, an electromotive force will appear to resist the change of the current. It is short for the phenomenon of 'electromagnetic induction'.
Inductance formula

ε is electromotive force, L is inductance, i is current, and t is time.
Inductance units and conversions
Using the International System of Units, the unit of inductance is Henry, labeled H. Commonly used units are millihen (mH), microhen (μH), Nahen (nH), and the conversion relationship between them is as follows:
IH=1000mH=1000,000μH=1000,000,000nH=1000,000,000,000pH

Application of inductance
Power inductor: mainly used for voltage conversion, commonly used DCDC circuit to use power inductor.
Decoupling inductance: mainly used to filter out the noise on the power line or signal line.
High-frequency inductors: mainly used in RF circuits to achieve bias, matching, filtering and other circuits.
