Low Profile, High Current Inductors with e-field Shield
DESIGN SUPPORT TOOLS click logo to get started
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) = 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
• High temperature, up to 155 °C
• Integrated E-Shield for maximum EMI
reduction (1)
• Excellent DC/DC energy storage up to 1 MHz
to 2 MHz. Filter inductor applications up the
SRF (see Standard Electrical Specifications
table).
• Integrated e-field shield eliminates need for
separate shielding
• 20 dB e-field reduction at 1 cm
- Measured vertically from top center of device
• Lowest DCR/μH, in this package size
• Handles high transient current spikes without saturation
• Coplanarity of the 4 terminals 100 μm
• AEC-Q200 qualified
•Patent pending
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
Note
(1) Maximum e-field reduction is realized with the IHLE shield is
connected to ground.
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
