Power Inductors’s main function are used as differential mode filtering, output chokes and as the energy storage magnetic in power supply topologies such a buck, boost. The main parameters for a power inductor are the rated current and the saturation current, the AC losses that are caused by the ripple current and frequency within the actual application. Standard parts offering range from mA to 150A, 100nH to 1mH in both surface mount and through-hole applications.
