Vishay Intertechnology Releases Industry’s First IHLP Inductor Series
Vishay Intertechnology’s new SGIHLP devices feature high operating temperatures to +180 °C in a rugged package
Vishay Intertechnology unveiled 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 introduced by Vishay are optimized for DC/DC converters and high current noise suppression filters in satellites and defense systems.
Key Applications for the inductors include
- low profile, high current power supplies and point of load (POL) converters;
- “flight-ready” solar inverters;
- high current filters;
- 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.
