Japanese electronics company TDK Electronics has extended its ERU27M series of SMD high current flat wire inductors comprising an isolated alloy powder core and flat wire helical winding.
The series of four variants is designed to meet the requirements for higher power densities and currents in automotive and industrial applications, by using an alloy powder core material that exhibits 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. The flat wire winding enables the components to have compact dimensions of 27.1 mm x 25.55 mm. The height ranges from 14.1 mm to 16.4 mm. The inductors are designed for operating temperatures from -40° C to 150° C.
The four new AEC-Q200-qualified energy storage chokes provide magnetic shielding and robust construction incorporating a third pin that is not electrically connected. They can be used in DC-DC converters, voltage regulator modules and point-of-load (POL) converters in the automotive sector, as well as in solar converters.
TDK Electronics can change certain production parameters to help customers optimize space and cost or provide fully customized designs.
