Vishay Dale
Low Profile, High Current Inductors with e-field Shield
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
• Material categorization: for definitions of compliance

Note
(1)
Maximum e-field reduction is realized with the IHLE shield is
connected to ground.

Notes
(1)
All test data is referenced to 25 °C ambient
(2)
Operating temperature range -55 °C to +155 °C
(3)
DC current (A) that will cause an approximate
T
of 40 °C
(4)
DC current (A) that will cause L to drop approximately 20 %

(5)
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.
