Automotive-grade IHSR high-temperature inductor delivers high current ratings

31-08-2022 | Vishay | Automotive Technologies

Vishay Intertechnology, Inc introduced the first AEC-Q200 qualified IHSR high-temperature inductor with current ratings to 155A in the 19mm x 17.1mm x 7mm 6767 case size. Intended for multi-phase, high current power supplies and input/output filters in automotive under the hood and ADAS applications, the Vishay Dale IHSR-6767GZ-5A provides a 50% reduction in DCR over typical power inductors and a smaller size than comparable ferrite-based solutions.

The automotive-grade inductor is optimised for energy storage in DC-DC converters up to 5MHz and high current filtering applications. With its high operating temperature, up to +155C, the device is also suitable for filtering and DC-DC conversion in ADAS and LIDAR microprocessors, 12V/48V vacuumless braking systems, OBCs, and brushless DC electric motors up to 140A. For these applications, the IHSR-6767GZ-5A's low typical DCR of 0.24mOhm and inductance of 0.22µH provide higher current density than competing technologies, with no hard saturation and more stable inductance and saturation over the whole operating temperature range.

Provided in a 100% lead (Pb)-free shielded composite construction that lowers buzz noise to ultra-low levels, the inductor delivers high resistance to thermal shock, moisture, and mechanical shock. It handles high transient current spikes with no saturation. The device is RoHS-compliant, halogen-free, and Vishay Green.
