Compact shielded inductor VISHAY IHLP2525AHER3R3M01 for dc dc converters and power supply applications
Vishay Dale IHLP Commercial Inductors, High Saturation Series
The Vishay Dale IHLP-2525AH-01 is a high-saturation series of commercial inductors featuring the lowest height (1.8 mm) in its package footprint. These shielded inductors offer excellent DC/DC energy storage up to 5 MHz and filter inductor applications up to SRF. They boast the lowest DCR/H in their package size, can handle high transient current spikes without saturation, and produce ultra-low buzz noise due to their composite construction. Designed for demanding applications, they are ideal for PDA, notebook, desktop, server, high current POL converters, low profile, high current power supplies, battery-powered devices, and DC/DC converters in distributed power systems, including those for FPGAs.

Notes
- All test data is referenced to 25 C ambient.
- Operating temperature range: -55 C to +125 C.
- The part temperature (ambient + temp. rise) should not exceed 125 C under worst-case operating conditions. Circuit design, component placement, PWB trace size and thickness, airflow, and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.
- 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 %.
