TDK Corporation presents the new BCEM series of EPCOS high-current chokes designed specifically for buck-boost converters in 48-V automotive power systems. These innovative SMD inductors have very compact dimensions of only 27.5 mm x 29.5 mm x 14.5 mm thanks to their ERU27 ferrite cores with flat windings. The new chokes feature inductance values of 3 µH to 11 µH and are designed for saturation currents of up to 50 A and operating temperatures of between -40 oC and +150 oC. The components are suited for switching frequencies from 100 kHz to 200 kHz, and are RoHS-compatible and qualified to AEC-Q200.
