Automotive Inductors, High Temperature (155 °C) Series
DESIGN SUPPORT TOOLS
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
• Rated operating voltage (across inductor) = 75 V
(1)
DC current (A) that will cause an approximate T of 40 °C
(2)
DC current (A) that will cause L
0
to drop approximately 20 %
FEATURES
• High temperature, up to 155 °C
• Shielded construction
• Excellent DC/DC energy storage up to 1 MHz
to 2 MHz. Filter inductor applications up the
SRF (see Standard Electrical Specifications
table)
• Lowest DCR/μH, in this package size
• Handles high transient current spikes without
saturation
• Ultra low buzz noise, due to composite
construction
• 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
