New power inductors with compact design

17-05-2016 | TDK | Passives

TDK Corporation has extended its portfolio of EPCOS ERU SMT power inductors with the ERU19 choke series that comprises ten different types. The inductance values of the new ERU chokes extend from 1.0µH to 30µH and their saturation currents range from 10.1ADC to 43ADC.

The outstanding feature of these new power inductors is their compact design: With a footprint of just 19.9mm x 20.5mm, they have low insertion heights of 8.35mm (1.0µH) to 10.85mm (30µH), 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 1.20mohm and 18.65mohm.

The B82559*A019 series of high-current chokes is designed for operating temperatures of between -40C and +150C. They can be used as output and storage chokes in a wide 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 new series are RoHS-compatible and qualification to AEC-Q200 is pending.

Typical applications include output and storage chokes for point-of-load (POL) converters, DC-DC converters, high-current switch-mode power supplies and xEV applications.
