Designed to Replace Larger Solutions, Device Offers Continuous High Temp. Operation to +155 °C for Renewable Energy, Industrial, and Telecom Applications

MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has introduced a new through-hole inductor that delivers a 420 A saturation current for 30 % inductance reduction in a compact 1500 case size. For renewable energy, industrial, and telecom applications, the Vishay Dale IHXL-1500VZ-51 offers very low typical DCR down to 0.12 mΩ and continuous high-temperature operation to +155 °C.

The shielded, composite construction of the device released today enables a compact size of 38.1 mm by 38.1 mm by 21.9 mm to support up to 150 A of continuous DC current. This allows the IHXL-1500VZ-51 to replace much larger competing solutions in high current input filters and DC/DC converters for high temperature industrial and solar and wind power applications, in addition to switching regulators, differential mode and boost power factor correction chokes, and telecom base station power supplies.
