MALVERN, Pa. — Jan. 23, 2019 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new Automotive Grade IHLP® low profile, high current inductor in the 4040 case size with an increased profile of 5.4 mm. With a high operating temperature range to +155 °C, the Vishay Dale IHLP-4040ED-5A has improved DCR over the standard 4.0 mm profile and is suited for under the hood automotive applications.
The AEC-Q200 qualified device released today is optimized for energy storage in DC/DC converters up to 2 MHz. It also provides excellent attenuation of noise in 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 motors, windshield wipers, power mirrors and seats, HID and LED lighting, and heating and ventilation blowers.
The IHLP-4040ED-5A features high efficiency with typical DCR from 1.05 mΩ to 204.0 mΩ and a wide range of inductance values from 0.33 µH to 75.0 µH. The device provides rated current to 36.0 A and handles high transient current spikes without saturation.
Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz to ultra low levels, the inductor offers high resistance to thermal shock, moisture, and mechanical shock. The IHLP-4040ED-5A is RoHS-compliant, halogen-free, and Vishay Green.
