WE-DD Series

Dual Winding Surface Mount Shielded Power Inductors

Würth Elektronik

The WE-DD series is well suited for SEPIC and CUK topologies and flyback applications.

Product Description

WE-DD Series is a coupled inductor series designed for DC/DC converters with SEPIC, CUK, and non-isolated flyback topologies. The coupled inductors are available in two general package sizes: 7mm x 7mm and 12mm x 12mm. Different heights are available within these package sizes, allowing designers to select the product with the best mechanical and electrical characteristics for an application. Due to the internal winding structure of the devices, Würth Elektronik's has divided the WE-DD Series into two groups. One is designed for SEPIC and CUK applications and the other for typical non-isolated flyback topologies; all coupled inductors can be used for both types of applications.
