Product Description
Eaton DRQ Series Dual Winding Power Inductors
The Eaton 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 in connecting windings in series or parallel to achieve 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.
