IHLP
®
Commercial Inductors, High Saturation Series
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
• Excellent DC/DC energy storage up to 5 MHz. Filter
inductor applications up to SRF (see “Standard Electrical
Specifications” table)
• IHLP design. PATENT(S):
www.vishay.com/patents
• Material categorization: for definitions of compliance

Notes
• All test data is referenced to 25 °C ambient
• Operating temperature range -55 °C to +125 °C
• 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
• Rated operating voltage (across inductor) = 50 V
