High Current Through Hole Inductor,
High Temperature Series
Notes
• All test data is referenced to 25 °C ambient
• Operating temperature range -55 °C to +155 °C
• The part temperature (ambient + temp. rise) should not exceed
155 °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
(1) DC current (A) that will cause an approximate ΔT of 40 °C
(2) DC current (A) that will cause L0 to drop approximately 20 %
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)
• Handles high transient current spikes without
saturation
• Ultra low buzz noise, due to composite
construction
• High temperature, up to 155 °C
• AEC-Q200 qualified
• PATENT(S): www.vishay.com/patents
• Material categorization:
for definitions of compliance please see
www.vishay.com/doc?99912
