Automotive-grade edge-wound inductor with low DCR reduces power losses

Vishay Intertechnology, Inc. has introduced a new Automotive Grade IHDF edge-wound, through-hole inductor with rated current up to 72A and saturation currents up to 230A. Featuring ferrite core technology and a low 15.4mm maximum profile, the Vishay Custom Magnetics IHDF-1300AE-1A operates over a demanding temperature range from -55C to +155C with low AC and DC power losses and exceptional heat dissipation.

The edge-wound coil construction provides low DCR of 1.1mOhm maximum, which minimises losses and enhances rated current performance for increased efficiency. Compared to competing ferrite-based solutions, the inductor offers 75% higher rated current. The device's low-profile package permits designers to fulfil the harsh mechanical shock and vibration conditions needed for AEC-Q200 qualification while minimising board height to save space.

With an operating voltage up to 500VDC, the AEC-Q200 qualified inductor is ideal for DC-DC converters, inverters, and motor and switching noise suppression. Target applications include high current, high temperature automotive systems, such as onboard chargers for EV and HEV.

The company can customise the device's mounting orientation, termination type, nominal inductance, and isolation voltage rating on request. To lower the risk of whisker growth, the inductor features a hot-dipped tin plating. The device is RoHS-compliant, halogen-free, and Vishay Green.
