TDK ERU33M Automotive Grade Inductors

TDK ERU33M Automotive Grade Inductors are PTH high-current flat-wire inductors designed for energy storage. These components use lead-free tinned terminals and require additional mechanical fixation for shock and vibration compliance. The ERU33M automotive inductor features an operating temperature range from -40°C to +150°C and a maximum DC resistance of 1.20mΩ. The devices use an isolated alloy powder core and offer an inductance range from 1.4µH to 7.2µH with a rated current range from 50A to 80A. Typical applications include Direct Current to Direct Current converters (DC-DC), Point-of-Load converters (POL), Voltage Regulator Modules (VRM), and solar converters.
