ERU27M SMD Alloy Powder Chokes

TDK Corporation extends its EPCOS series of ERU27M SMD high-current flat-wire inductors consisting of an isolated alloy powder core and flat-wire helical winding. This series meets the requirements for increased power densities and currents in automotive and industrial applications by using an alloy powder core material exhibiting a softer saturation characteristic than the core material used previously.

Designed for rated currents from 36 A to 48 A, these surface-mountable components cover a range of inductance values from 2.3 µH to 8.5 µH. DC resistances are as low as 0.68 mΩ to 1.66 mΩ. Thanks to the flat wire winding, the components have very compact dimensions of only 27.1 mm x 25.55 mm, and the height ranges from 14.1 mm to 16.4 mm. The inductors are designed for operating temperatures from -40°C to +150°C.

With this magnetically shielded and robust construction with a third pin that is not electrically connected, these four AEC-Q200-qualified energy storage chokes can be used in DC/DC converters, VRM modules, and POL converters especially in the automotive sector, but also in solar converters.
