Vishay Intertechnology Introduces Industry's First IHLP® Inductor Series Qualified to MIL-STD-981 Class S for Space-Grade Applications

SGIHLP Devices Feature High Operating Temperatures to +180 °C in a Rugged Package

MALVERN, Pa. — April 25, 2018 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of low profile, high current IHLP® inductors that are the industry's first to meet the requirements of MIL-STD-981 class S. Designed to provide high reliability in space-grade applications, inductors in the Vishay Custom Magnetics SGIHLP series feature a ruggedized package and perform at high operating temperatures to +180 °C.

Featuring a magnetically shielded construction, the devices released today are optimized for DC/DC converters and high current noise suppression filters in satellites and defense systems. Applications for the inductors include low profile, high current power supplies and point of load (POL) converters; "flight-ready" solar inverters; high current filters; and DC/DC converters in distributed power systems.

Offered in five case sizes, the SGIHLP series features high efficiency with typical DCR from 0.56 mΩ to 240 mΩ and a wide range of inductance values from 0.22 µH to 100 µH. Based on proven IHLP technology, the devices provide rated currents to 100 A and handle high transient current spikes without saturation. The inductors offer excellent inductance and saturation stability over the complete operating temperature range.
