Composite shielded inductor VISHAY IHLP3232DZERR33M01 designed for dc dc converter and energy storage
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 %.
