Eaton's DRQ power inductors utilize ferrite material in a dual winding, shielded drum core construction. DRQ inductors can be used as either a single inductor, or in coupled inductor/transformer applications. Windings can be connected in series or in parallel, offering a broad range of inductance and current ratings. The DRQ is available in four sizes. Peak current ratings range from 0.13 A to 56 A.  RMS current ratings range from 0.128 A to 17.9 A. Inductance ratings range from 0.33 uH to 4.02 mH. DRQ power inductors can be used in several applications including desktop and servers, DVD and media players, portable and handheld devices, LCD panels, as a transformer in SEPIC, flyback, as an inductor: buck, boost, coupled inductor, DC-DC converters, VRM inductor for CPU and DDR power supplies, input and output filter chokes.
