Flat wire SMT high-current chokes

31 March 2021 Passive Components

TDK has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series, comprised of 10 different types. The inductance values of the new B82559B*A016 series, which replaces the former B82559A*A016 series, extend from 1,0 µH to 30 µH and their saturation currents range from 10,3 A d.c. to 40,4 A d.c. at 25°C.

A key feature of these new power inductors is their compact design: with a footprint of just 17,3 x 16,5 mm, they take up 12% less space on the PCB than their predecessor. The low insertion heights of 7,55 mm (1,0 µH) to 11,1 mm (30 µH) vary depending on the type. This low-profile design is based on a flat rectangular helical winding technology, which also results in lower losses.

The DC resistances are between 1 mΩ and 15,4&nbspmΩ. The new series of high-current chokes is designed for operating temperatures between -40°C and +150°C. Its additional third soldering pad results in high mechanical stability on the PCB.

The new components can be used as output and storage chokes in a wide variety of power supply topologies including point-of-load (POL) converters, DC-DC converters, high-current switch-mode power supplies and inverters for photovoltaics systems and automotive applications. The components are RoHS-compatible and qualified to AEC-Q200.
