Low resistance automotive inductors VISHAY IHLP5050EZERR33MA1 designed for filter and energy storage
Vishay Dale IHLP-5050EZ-5A Automotive Inductors
The Vishay Dale IHLP-5050EZ-5A series offers high-temperature automotive inductors designed for demanding applications up to 155 C. These shielded construction inductors provide excellent DC/DC energy storage up to 2 MHz and are ideal for filter inductor applications up to the SRF. They feature the lowest DCR/H in their package size, handle high transient current spikes without saturation, and offer ultra-low buzz noise due to their composite construction. The series is AEC-Q200 qualified.

Notes
- All test data is referenced to 25 C ambient.
- Operating temperature range: -55 C to +155 C.
- The part temperature (ambient + temp. rise) should not exceed 155 C under worst-case operating conditions.
- Rated operating voltage (across inductor) = 75 V.
- (1) DC current (A) that will cause an approximate T of 40 C.
- (2) DC current (A) that will cause L0 to drop approximately 20 %.
