SMD Dual Winding Shielded Power Inductors - DRQ series DRQ series dual winding inductors for use in either single inductor or a coupled inductor applications (1:1 turns ratio). The DRQ inductors offer a wide range of inductance and current ratings as they can be either connected in series or parallel. Designed with a ferrite core the DRQ series have a 125°C maximum operating temperature. Applications for the DRQ series include: Use as a transformer - SEPIC, flyback; Use as an inductor - buck, boost coupled; DC-DC converters; VRM inductor for CPU and DDR power supplies; Input and output filter chokes
