Moulded double choke

18 July 2018 Passive Components

Würth Elektronik eiSos unveiled the WE-MCRI, a first-of-its-kind double choke taking advantage of moulding technology. With its soft saturation characteristics, it is above all suited for DC-DC converter applications.

The component consists of two identical round wire-windings compacted in a metal powder material. Designed for SMT assembly, it is compact at 10 x 11,5 x 9 mm, and is designed for a rated current up to 17 A and a saturation current up to 43,5 A. Thanks to their special winding style, the WE-MCRI series components achieve a coupling coefficient of up to 0,995 which means much lower leakage inductance than similar coupled inductors.

These double power chokes are ideal for SEPIC and uk converters for which a high rated current and saturation current with a high coupling coefficient are called for. Further applications include flyback converters with a 1:1 turn ratio as well as step-up / step-down converters with isolated secondary output voltage.
