Product Description
Vishay Dale IHLP-4040DZ-8A Automotive Inductors
The Vishay Dale IHLP-4040DZ-8A series offers high-temperature (up to 180 C) automotive-grade inductors designed for demanding applications. These shielded inductors provide excellent DC/DC energy storage up to 2 MHz and are suitable for filter inductor applications up to the SRF. Key advantages include the lowest DCR/H in their package size, the ability to handle high transient current spikes, and ultra-low buzz noise due to their composite construction. They are AEC-Q200 qualified and feature the IHLP design.

Dimensions
Refer to datasheet for detailed dimension diagrams for values 2.2 H and above, and 1.5 H and below.
Notes
- All test data is referenced to 25 C ambient.
- Operating temperature range: -55 C to +180 C.
- Part temperature (ambient + temp. rise) should not exceed 180 C under worst-case operating conditions.
- Rated operating voltage (across inductor) = 75 V.
