What is claimed to be the industry's first Automotive Grade IHLP low profile, high current inductor in the 19 mm by 19 mm by 7 mm 7575 case size has been released by Vishay.

Offering high temperature operation to +155 °C for under the hood automotive applications, the Vishay Dale IHLP 7575GZ-5A offers up to 30 % lower DCR and up to 35 % higher current ratings than devices in the 6767 case size, at a 50 % lower cost than devices in the 8787 case size.

This AEC-Q200 qualified inductor is optimised for energy storage in DC/DC converters up to 2 MHz and high current filtering applications up to the SRF of the inductor.

With its high operating temperature, the device is designed for filtering and DC/DC conversion in engine and transmission control units, diesel injection drivers, and entertainment / navigation systems, in addition to noise suppression for high current BLDC motors, windshield wipers, power mirrors and seats, HID and LED lighting, and heating and ventilation blowers.

Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the IHLP-7575GZ-5A 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.
