New Vishay Intertechnology Automotive-Grade Low-Profile, High-Current Inductor Offers Continuous High-Temperature Operation to +180 °C in 4040 Case Size

Vishay » IHLP-4040DZ-8A

Vishay Intertechnology 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.

Vishay IHLP-4040DZ-8A

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.
