Fixed Inductors: OverviewAn inductor, also known as a coil, choke or reactor, is an electrical component consisting of a wire wound into a coil. Its main purpose is to store energy in the form of a magnetic field. This field is generated when a current passes through the inductor. Fixed inductors have a specific resonance frequency, and are designed to sustain that frequency with minimal losses.HCMA0503-R20-R application field and working principleThe HCMA0503-R20-R is a fixed inductor manufactured by Vishay Intertechnology. It is a medium-sized inductor that is designed to operate from commercial to industrial temperature ranges.
