Offered in the 2525 Case Size With a Slim 3 mm Profile, AEC-Q200 Qualified Device Features High Operating Temperature to +155 °C

MALVERN, Pa., Dec. 01, 2021 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new AEC-Q200 qualified IHSR high temperature inductor in the 7.4 mm by 6.6 mm by 3.0 mm 2525 case size. Designed for multi-phase, high current power supplies and filters in automotive under the hood and ADAS applications, the Vishay Dale IHSR-2525CZ-5A offers a 50 % reduction in DCR over typical power inductors and excellent temperature stability for inductance and saturation compared to ferrite solutions.

The Automotive Grade inductor released today is optimized for energy storage in DC/DC converters up to 10 MHz and high current filtering applications up to the SRF of the inductor. With its high operating temperature up to +155 °C, the device is designed for filtering and DC/DC conversion in engine and transmission control units, ADAS microprocessors, and entertainment / navigation systems, in addition to noise suppression for motors, windshield wipers, power mirrors and seats, and heating and ventilation blowers.

The IHSR-2525CZ-5A’s low typical DCR of 0.38 mΩ and inductance of 0.056 µH allow for higher current density than competing technologies, while its 3 mm profile enables slimmer end products. 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.
