Product Description

Product Overview

The Vishay Dale IHLP Commercial Inductors, High Saturation Series are designed for high current applications with a frequency range up to 5.0 MHz. These inductors feature shielded construction, lowest DCR/H in their package size, and ultra-low buzz noise due to their composite construction. They are capable of handling high transient current spikes without saturation, making them ideal for various power conversion and electronic device applications.

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.
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 L0 to drop approximately 20 %.
