• 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 DC/DC energy storage up to 1 MHz to 2 MHz.
Filter inductor applications up to SRF (see “Standard
Electrical Specifications” table)
• IHLP design. PATENT(S): www.vishay.com/patents

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) = 40 V
(1) DC current (A) that will cause an approximate T of 40 °C
(2) DC current (A) that will cause L to drop approximately 20 %
