Product Overview
The Vishay Dale IHLP Commercial Inductors, High Saturation Series are shielded construction inductors designed for high-frequency applications up to 5.0 MHz. They offer the lowest DCR/H in their package size, handle high transient current spikes without saturation, and feature ultra-low buzz noise due to their composite construction. These inductors are ideal for various power applications including 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 FPGAs.

Dimensions
Note: Diagrams apply to specific inductance ranges.
For values 1.0 H and above:
- Overall dimensions: 0.425 in [10.795 mm] 0.01
- Width: 0.158 in [4.0 mm] max.
- Height: 0.118 in [3.0 mm] 0.01
- Pad layout (approximate): 0.400 in [10.160 mm] 0.005 x 0.400 in [10.160 mm] 0.005
For values 0.56 H and below:
- Overall dimensions: 0.158 in [4.0 mm] 0.01
- Width: 0.079 in [2.0 0.3] 0.01
- Height: 0.185 in [4.7 0.3] 0.01
- Pad layout (approximate): 0.128 in [3.251 mm] x 0.229 in [5.817 mm]
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 %.
