Power Inductor Products Overview

Power Inductors are used in variety of functions including differential mode filtering, output chokes and as the energy storage device in power supply topologies such a buck, boost, SEPIC and Cuk.   The key parameters for a power inductor are the rated current (to ensure the part does not overheat), the saturation current (to ensure it will not saturate at peak application current) as well as paying close attention to the AC losses that are caused by the ripple current and frequency within the application.

Catalog offerings range from mA to 150A, 100nH to 1mH in both surface mount and through-hole applications.
