Low Profile, High Current IHLP® Inductors
FEATURES
• Shielded construction
• Lowest DCR/μH, in this package size
• Handles high transient current spikes without
saturation
• Ultra low buzz noise, due to composite
construction
• Excellent temperature stability for inductance and
saturation

APPLICATIONS
• PDA/notebook/desktop/server applications
• High current POL converters
• Low profile, high current power supplies
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 to drop approximately 20 %
0
(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.
