Vishay Dale
Low Profile, High Current IHLP® Inductors
FEATURES
• Shielded construction
• Frequency range up to 1.0 MHz
• 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
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912

DC current (A) that will cause an approximate T of 40 °C
DC current (A) that will cause L0 to drop approximately 20 %
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.
