TDK expands compact high-current choke series ERU33 toward higher currents with new core material
TDK Corporation (TSE:6762) presents the B82559A*A033 series of new shielded EPCOS ERU33 high-current chokes for through-hole mounting. Designed for very 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. 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.

TDK Product Features
TDK offers a wide range of high-current flat wire inductors.
ERU inductors have compact dimensions due to flat helical winding with a rectangular wire, and feature low RDC and high saturation currents. High-temperature usage up to 150 °C is possible due to ferrite core material. The components are magnetically shielded and are designed in a self-leaded construction with underbody termination (SMD). They are RoHS-compatible and partly AEC-Q200 qualified. Typical applications include automotive, industrial and telecommunications.
Power Cube Metal (PCM) series with its hybrid construction are optimized for high saturation currents and low DC resistances. Typical applications include primary DC/DC converters in automotive such as ADAS, power supplies for servers and base stations, and various types of DC/DC inverters. The PCM is also ideal for interference suppression, such as electric motors in vehicles. PCM’s optimal saturation properties are achieved through an alloy core. Flat wire winding keeps the losses as low as possible and a closed housing made of ferrite material results in an outstanding EMC performance. The lead frame structure is ideal for automatic solder joint inspection and has excellent coplanarity. These powerful inductors are designed for a wide temperature range from -55 °C to +165 °C and are qualified according to AEC-Q200.
