The DRQ series offers dual winding, high power density, shielded drum core power inductors. These versatile components can function as single inductors or in coupled inductor/transformer configurations with a 1:1 turns ratio. They provide flexibility through series or parallel winding connections, enabling a wide range of inductance and current ratings. Designed for demanding applications, these inductors feature a ferrite core material and 200 Vac isolation between windings.
