Product Overview

The Vishay Dale IHCL-4040DZ-5A is a low-profile, high-current coupled inductor designed for high-temperature applications up to 155 C. It features shielded construction, a frequency range up to 5.0 MHz, and offers the lowest DCR/H in its package size. This inductor handles high transient current spikes without saturation and provides ultra-low buzz noise due to its composite construction. With coupling greater than 90%, it is optimized for SEPIC converters and is AEC-Q200 qualified. Applications include SEPIC converters, DC/DC converters, common mode applications, and LED lighting.

Technical Specifications

Notes:
(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 %.
(3) In this configuration, current flowing opposite directions through coils cancels and the 1.0 H inductance is very stable with varying current. Observe the heat rating current to avoid excessive temperature rise in this configuration.

General 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.
Rated operating voltage (across inductor) = 50 V.
For SEPIC operation, limit VIN and VOUT to 25 V max. as it can generate up to 2x the input or output voltage across the inductor.
