IHLP-2525CZ-11

Vishay Dale

FEATURES

• Shielded construction

• Frequency range up to 1 MHz

• Lowest DCR/µH, in this package size

• Powdered iron composition provides soft saturation

• Handles high transient current spikes without hard

saturation

• Ultra low buzz noise, due to composite construction

• 100 % lead (Pb)-free and RoHS compliant

Manufactured under one or more of the following:

US Patents; 6,198,375/6,204,744/6,449,829/6,460,244.

Several foreign patents, and other patents pending.

NOTES:

1. All test data is referenced to 25 °C ambient

2. Operating Temperature Range - 55 °C to + 125 °C

3. DC current (A) that will cause an approximate

ΔT of 40 °C

4. DC current (A) that will cause Lo to drop approximately 20 %

5. 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.
