New Vishay Intertechnology Through-Hole Inductor Packs a 420 A Saturation Current Into Compact 1500 Case Size


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

Vishay Intertechnology, Inc. (NYSE: VSH) today 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.

The IHXL-1500VZ-51 handles high transient current spikes without hard saturation, offering soft saturation of 20 % at 195 % of rated current. RoHS-compliant, halogen-free, and Vishay Green, the device provides high resistance to thermal shock, moisture, and mechanical shock.
