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/µH, 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
•Low profile, high current power supplies
•Battery powered devices
•DC/DC converters in distributed power systems
•
DC/DC converter for Field Programmable Gate Array (FPGA)
