Vishay has introduced an AEC-Q200 qualified IHSR high temperature inductor that combines a current rating of 155A with a compact 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-percent reduction in DCR over typical power inductors and a smaller size than similar ferrite-based solutions. The product is available from distributor New Yorker Electronics.
This automotive grade inductor is optimized for energy storage in DC/DC converters up to 5MHz and high current filtering applications. With its high operating temperature up to +155°C, the Vishay IHSR Inductor is also suitable for filtering and DC/DC conversion in ADAS and lidar microprocessors, 12V / 48V vacuum-less braking systems, OBCs, and brushless DC electric motors up to 140A. For these applications, Vishay states that the IHSR-6767GZ-5A’s low typical DCR of 0.24mΩ and inductance of 0.22µH allow for higher current density than competing technologies, with no hard saturation and more stable inductance and saturation over the entire operating temperature range.
Packaged in a 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.
