Low Profile, High Current IHLP
®
Inductors
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 T of 40 °C
(4)
DC current (A) that will cause L
0
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.
FEATURES
• Shielded construction
• Excellent DC/DC energy storage up to 1 MHz to
2 MHz. Filter inductor applications up to SRF
(see “Standard Electrical Specifications” table)
• Lowest DCR/μH, in this package size
• Handles high transient current spikes without
saturation
• Ultra low buzz noise, due to composite construction
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
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)
• Currently not recommended for automotive applications
