EPCOS / TDK ERU 33 Chokes

EPCOS / TDK ERU 33 Chokes are PTH flat wire high current inductors with high rated current and low DC resistance for through-hole mounting. These chokes are designed for high saturation currents from 32A to 83A at +100°C. The series offers a 3.2μH to 10μH rated inductance range, ±12% inductance tolerance, and <2MHz resonant frequency. Other features include a low profile, a small footprint, and a 0.85mΩ to 1.2mΩ DC resistance range. The ERU 33 chokes are available in a compact size (33mm x 33mm x 15mm) due to flat wire winding. 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. EPCOS / TDK ERU 33 Chokes operate in a -40°C to +150°C temperature range and are easily customizable. The series is AEC-Q200 REV D-qualified and RoHS compliant.
