TDK Corp. has expanded its line of EPCOS ERU SMT power inductors with the introduction of the ERU19 choke series that comprises ten different types. The inductance values of the ERU chokes extend from 1μH to 30μH and their saturation currents range from 10.1ADC to 43ADC.

ERU19 choke series

The outstanding feature of these power inductors is their compact design: With a footprint of just 19.9mm x 20.5mm, they have low insertion heights of 8.35mm to 10.85mm, depending on the type.

This low-profile design is based on a flat rectangular helical winding technology which results in lower losses. The DC resistances are between 1.20mΩ and 18.65mΩ.

The B82559*A019 series of high-current chokes is designed for operating temperatures of between -40°C and 150°C. They can be used as output and storage chokes in a variety of power supply topologies. These include point-of-load (POL) converters, DC-DC converters, high-current switch-mode power supplies and xEV applications.

The components of the series are RoHS-compatible and qualification to AEC-Q200 is pending.
