Würth Elektronik WE-DD Shielded Coupled Inductors
Würth Elektronik WE-DD Shielded Coupled Inductors offer flexibility in size and are available in crossed and straight pin layout. These inductors have a maximum current handling capability of 8.6A DC current and up to 19A saturation current. They 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. Würth Elektronik has divided the WE-DD Coupled Inductors into two groups: One is designed for SEPIC and Ćuk applications and the other for typical non-isolated flyback topologies.
