Vishay Intertechnology Automotive Grade IHSR High Temperature Inductor Delivers High Current Ratings Up to 155 A in 6767 Case Size

Vishay Intertechnology introduced the first AEC-Q200 qualified IHSR high temperature inductor with current ratings to 155 A in the 19.0 mm by 17.1 mm by 7.0 mm 6767 case size.

Designed 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 offers a 50 % reduction in DCR over typical power inductors and a smaller size than similar ferrite-based solutions.

The Automotive Grade inductor released is optimized for energy storage in DC/DC converters up to 5 MHz and high current filtering applications. With its high operating temperature up to +155 °C, the device is also suitable for filtering and DC/DC conversion in ADAS and LIDAR microprocessors, 12 V / 48 V vacuum-less braking systems, OBCs, and brushless DC electric motors up to 140 A. For these applications, the IHSR-6767GZ-5A’s low typical DCR of 0.24 mΩ and inductance of 0.22 µH allow for higher current density than competing technologies, with no hard saturation and stable inductance and saturation over the entire operating temperature range.

Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra low levels, the inductor offers high resistance to thermal shock, moisture, and mechanical shock, and handles high transient current spikes without saturation. The device is RoHS-compliant, halogen-free, and Vishay Green.
