Offers Continuous High-Temperature Operation to +180 °C in 4040 Case Size. Latest IHLP® Device Features Wide Inductance Range From 0.47 µH to 47 µH and Low 4.0 mm Profile
MALVERN, Pa. — Feb. 6, 2015 — Vishay Intertechnology, Inc. introduced a new automotive-grade IHLP® low-profile, high-current inductor in the 4040 case size featuring an industry-high continuous operating temperature range to +180 °C. Offering a low profile of 4.0 mm, the Vishay Dale IHLP-4040DZ-8A provides a wide range of inductance values from 0.47 µH to 47 µH.
With a frequency range up to 1 MHz, the AEC-Q200-qualified device released today serves as a high-performing, space- and power-saving solution for voltage regulator modules (VRM), high-current noise filters, and DC/DC converters in high-temperature automotive applications. End products include engine and transmission control units, diesel injection drivers, entertainment and navigation systems, noise suppression for motors, windshield wipers, HID and LED lighting, heating and ventilation blowers, and power seats and mirrors.
The IHLP-4040DZ-8A handles high transient current spikes without hard saturation. Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the device is specified for an operating temperature range of 55 °C to +180 °C, with high resistance to thermal shock, moisture, mechanical shock, and vibration. The inductor is RoHS-compliant, halogen-free, and Vishay GREEN.
