Power Magnetics

Coilcraft is a global supplier of power magnetics, including power inductors, current sensors, and planar transformers designed for the highest efficiency performance. The wirewound inductors feature a ferrite or powdered iron core and come in a wide range of shapes and sizes. For an efficient power supply, key attributes of a power inductor are the inductance, the current, and the DC resistance (DCR).
