Automotive Grade IHLP Inductor with Low 3mm Profile for DC/DC Conversion in Transmission Control Units

Vishay Intertechnology, Inc. has expanded its high-temperature Automotive Grade IHLP low-profile inductors series with a new device in the 2020 case size. This new high current IHLP-2020CZ-8A inductor is optimized for energy storage in DC/DC converters up to 2MHz. This device combines a continuous operating temperature to +180°C with a low profile of 3mm to save space in under the hood automotive applications. This 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 Inductor features high efficiency with typical DCR from 3.95mΩ to 195mΩ and a wide range of inductance values from 0.22µH to 15.0µH. It provides a rated current to 18 A and handles high transient current spikes without saturation. This AEC-Q200 qualified Inductor provides excellent attenuation of noise in high current filtering applications up to the SRF of the inductor and is packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz to ultra-low levels. Moreover, this RoHS-compliant inductor offers high resistance to thermal shock, moisture, and mechanical shock.

Features

• High temperature, up to 180 °C

• Shielded construction

• Excellent DC/DC energy storage up to 1MHz to 2MHz. Filter inductor applications up the SRF (see Standard Electrical Specifications table)
