IHLP-2525AH-01
Vishay Dale
FEATURES
Lowest height (1.8 mm) in this package footprint
Shielded construction
Frequency range up to 5.0 MHz
Lowest DCR/H, in this package size
Handles high transient current spikes without 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.
APPLICATIONS
PDA/Notebook/Desktop/Server applications
High current POL converters
