High Temperature Inductors Outfit Multi-Phase Power Supplies

Vishay Intertechnology offers the first device in its IHSR series of high temperature commercial inductors, the Vishay Dale IHSR-4040DZ-51. Designed for multi-phase, high current power supplies and filters in computer, industrial, and telecom applications, the component offers a 50 % reduction in DCR over typical power inductors and a 20 % or greater profile reduction over similar ferrite products. In addition, the inductor boasts an unprecedented standard DCR tolerance of 5 %, with 3 % available for more accurate current sensing. With a frequency range up to 5 MHz, applications include notebooks, desktop PCs, servers, high-current power supplies and filters, and dc/dc converters for distributed power systems.

 

The IHSR-4040DZ-51's low typical DCR of 0.520 mΩ and inductance of 0.130 µH allow for higher current density than competing technologies, while its 4 mm profile enables slimmer end products. The inductor offers high temperature operation to +155 °C, rated current to 92 A, and handles high transient current spikes without saturation. The device is available in the 10 mm by 10 mm 4040 case size; additional case sizes will be offered in the future. For more details, peruse the IHSR-4040DZ-51 datasheet.
