Shielded Composite Inductor VISHAY IHLP4040DZER4R7M11 Low DCR Series for DC DC Conversion Applications
Vishay Dale IHLP Commercial Inductors, Low DCR Series
The Vishay Dale IHLP Commercial Inductors, Low DCR Series are designed for high-performance applications requiring low DC resistance and excellent temperature stability. These shielded inductors feature a composite construction that minimizes buzz noise and handles high transient current spikes without saturation. With a frequency range up to 1.0 MHz, they are ideal for power converters, low-profile 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.
- 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 %.
