IHLP® Automotive Inductors, High Saturation Series
DESIGN SUPPORT TOOLS AVAILABLE
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
(1) DC current (A) that will cause an approximate T of 40 °C
(2) DC current (A) that will cause L0 to drop approximately 20 %
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 DC/DC energy storage up to 5 MHz.
Filter inductor applications up to SRF (see
“Standard Electrical Specifications” table)
• AEC-Q200 qualified
• IHLP design. PATENT(S): www.vishay.com/patents
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• Engine and transmission control units
• Diesel injection drivers
• DC/DC converters for entertainment/navigation systems
• Noise suppression for motors: windshield wipers / power
seats / power mirrors / heating and ventilation blower /
HID lighting
• LED drivers
