Vishay Intertechnology, Inc. (NYSE: VSH) expanded its offering of high temperature Automotive Grade IHLP® low profile, high current inductors with a new device in the 2020 case size. The Vishay Dale IHLP-2020CZ-8A combines a high continuous operating temperature to +180 °C with a low profile of 3 mm to save space in 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, advanced driver assistance systems, exhaust gas recycling pumps, 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-2020CZ-8A features high efficiency with typical DCR from 3.95 mΩ to 195 mΩ and a wide range of inductance values from 0.22 μH to 15.0 μH. The device provides rated current to 18 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 RoHS-compliant inductor offers high resistance to thermal shock, moisture, and mechanical shock.
