TDK Offers Compact High-Current Chokes For Automotive And Industrial Applications

March 27, 2023

TDK High-current compact chokes

TDK Corporation presents the B82559A*A033 series of new shielded EPCOS ERU33 high-current chokes for through-hole mounting. Designed for high saturation currents from 32 A to 83 A at 100 °C, the six new types cover a range of inductance values from 3.2 µH to 10 µH. DC resistances are as low as 0.85 mΩ or 1.2 mΩ, depending on the type.

TDK High-current compact chokes

Thanks to the flat wire winding, the chokes have very compact dimensions of only 33 x 33 x 15 mm. By thermally connecting the flat wire winding to the core, the large ferrite surface can be coupled to a heat sink for effective heat dissipation. In addition to the standard types, customized variants with other inductance values can also be realized.

The RoHS-compatible and AEC-Q200 REV D-qualified inductors are designed for operating temperatures from -40 °C to 150 °C. Automotive applications are buck-boost chokes for DC-DC converters (e.g. for 48 V on-board power supplies or differential mode chokes in the input filter of onboard chargers. In industrial electronics, they can be used as storage and output chokes in high-current supplies and PoL supplies.

Features & Applications

Main Applications
  • Buck-Boost DC-DC converter for 48 V on-board power supplies
  • Storage and output chokes in high current supplies
Main Features and Benefits
  • High saturation currents from 32 A to 83 A
  • Low DC resistances of 0.85 mΩ or 1.2 mΩ
  • Very compact dimensions of only 33 x 33 x 15 mm
