TDK Announces New EPCOS Series of Compact SMT High-Current Chokes

EPCOS ERU19 Series Ideal for Designs Needing Power Inductors for Tight-Fitting Spaces

ISELIN, NJ--(Marketwired - May 12, 2016) - TDK Corporation today announced that it has expanded its portfolio of EPCOS ERU SMT power inductors with the introduction of the ERU19 choke series, which is comprised of ten different inductor types. The inductance values of the new ERU chokes extend from 1.0 µH to 30 µH and their saturation currents range from 10.1 A DC to 43 A DC. The outstanding feature of these new power inductors is their compact design: With a footprint of just 19.9 mm x 20.5 mm, they have low insertion heights of 8.35 mm (1.0 µH) to 10.85 mm (30 µH), 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 1.20 mΩ and 18.65 mΩ.

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 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.

Main applications

  • Output and storage chokes for point-of-load (POL) converters, DC-DC converters, high-current switch-mode power supplies and xEV applications

Main features and benefits

  • Compact dimensions thanks to flat rectangular helical winding
  • High saturation currents of up to 43 A DC
  • Low loss
