Automotive Grade IHSR High Temperature Inductor Delivers High Current Ratings and Provides Ultra Low DCR

Vishay Intertechnology, Inc. has introduced the new AEC-Q200 qualified IHSR high-temperature inductor with current ratings of 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 new IHSR-6767GZ-5A inductor offers a 50 % reduction in DCR over typical power inductors and 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, this 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 allows for higher current density than competing technologies, with no hard saturation and more stable inductance and saturation over the entire operating temperature range.

Features
