Double choke in metal powder molding
The WE-MCRI double choke designed by Würth Elektronik consists of two identical round wire-windings compacted in a metal powder material, offering soft saturation characteristics for DC/DC converter applications.

The 10x11.5x9mm SMT double choke is designed for a rated current up to 17A and a saturation current up to 43.5A. Thanks to their special winding style, the WE-MCRI series components excel with an outstanding coupling coefficient of up to 0.995 which means much lower leakage inductance than similar coupled inductors. These double power chokes are the perfect solution for SEPIC and Ćuk 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.
