Inductors operate up to 180°C

By Gina Roos, editor-in-chief

Vishay Intertechnology, Inc. released a new IHDM edge-wound, through-hole inductor with rated current up to 150 A for industrial and military applications. Featuring a powdered iron alloy core technology, the Vishay Custom Magnetics IHDM-1008BC-30 provides stable inductance and saturation over an extended operating temperature range from -40°C to 180°C with low power losses and excellent heat dissipation.

Featuring a powdered iron alloy core, the IHDM-1008BC-30 provides low direct current of resistance (DCR) down to 0.25 mΩ, which minimizes losses and improves rated current performance for increased efficiency. Compared to competing ferrite-based solutions, Vishay said the IHDM-1008BC-30 offers 30% higher rated current and 30% higher saturation current levels at 125°C.

The device’s operating voltage up to 350 V make it suited for DC/DC converters, inverters, motor and switching noise suppression, and high power switch-mode power supplies in high current, high temperature applications, including industrial solar systems and charging stations for electric vehicles, as well as military defense systems.

Customization is available for performance ratings, and the mounting method. Options include bare copper, surface-mount, and press fit. The inductor features a hot-dipped tin plating to reduce the risk of whisker growth. The device is RoHS-compliant, halogen-free, and Vishay Green.

The inductor (25 × 20 × 23 mm) is available with lead times of 12 weeks. Pricing for U.S. delivery is $7.39 each in quantities of 1,000.
