Reliability test of inductance value of one-piece molded inductor

2025-03-26 08:52

Inductance is the ratio of the magnetic flux of the wire to the current that produces the alternating magnetic flux inside and around the wire when an alternating current passes through the wire.

L value

Definition: In the absence of external power supply magnetic flux, the ratio of the magnetic flux λ of a current-carrying coil with a current value of i to the current magnitude i is the self-inductance value.
