Vishay Dale IHLP Commercial Inductors, Low DCR Series
The Vishay Dale IHLP Commercial Inductors, Low DCR Series are designed for excellent DC/DC energy storage up to 1 MHz to 2 MHz and filter inductor applications up to SRF. These shielded construction inductors offer an operating temperature range of -55 C to +125 C, lowest DCR/H in their package size, and the ability to handle high transient current spikes without saturation. Their ultra-low buzz noise is attributed to their composite construction. These inductors are ideal for PDA/notebook/desktop/server applications, high current POL converters, low profile, high current power supplies, battery-powered devices, DC/DC converters in distributed power systems, and DC/DC converters for Field Programmable Gate Arrays (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.
- Rated operating voltage (across inductor) = 50 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 %.
