Inductor

nounStandard termElectronics

A passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it.

An inductor typically consists of an insulated wire wound into a coil around a magnetic or air core. It resists sudden changes in current by inducing an opposing voltage, a property called inductance. Engineers use inductors in tuned circuits, power supplies, and filters to block high-frequency AC while allowing DC to pass.

Heard on the job

The buck converter is failing because the inductor is saturating at peak load.
