TDK OFFERS SAMPLE KIT FOR THE ERU 33 SERIES OF COMPACT HIGH-CURRENT CHOKES

The sample kit contains two pieces of each of the six standard types of this series. In addition to the standard types in the sample kit, customized variants of the chokes with other inductance values can also be realized.

TDK OFFERS SAMPLE KIT FOR THE ERU 33 SERIES OF COMPACT HIGH-CURRENT CHOKES

TDK Corporation presents a sample kit for the B82559A*A033 series of shielded EPCOS ERU 33 high-current chokes.

Designed for very high saturation currents from 32 A to 83 A at +100 °C, these through-hole mountable components 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. Thanks to the flat wire winding, the components have very compact dimensions of only 33 x 33 x 15 mm. By thermally connecting the flat coils to the electrically insulated core, the choke can be attached to a heat sink to effectively dissipate the heat.

The RoHS-compatible and AEC-Q200 REV D-qualified inductors are designed for operating temperatures from -40 °C to +150 °C. Typical automotive applications are buck-boost chokes for DC-DC converters (e.g., for 48 V on-board power supplies or for 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 point-of-load (PoL) converters.

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 up to 83 A
  • Low DC resistances down to 0.85 mΩ
  • Very compact dimensions of only 33 x 33 x 15 mm
  • Effective heat dissipation by directly attaching a heat sink
