Coupled Inductors

.hide-partial { max-height: none; } .show-more { display: none; }

Coilcraft Coupled Inductors offer a small footprint inductor featuring high efficiency and excellent current handling. The different series of Coilcraft Coupled Inductors are ideal for use in flyback, multi-output buck, and SEPIC applications with some also suited for Zeta applications. The inductors can be used as two single inductors connected in series or parallel or common mode chokes with some also suitable for wideband or 1:1 transformers.
