Edge-Wound Inductor Handles Temps to +180°C and Current to 150A

August 21, 2019 by Paul Shepard

Vishay Intertechnology, Inc. has introduced a new IHDM edge-wound, through-hole inductor with rated current up to 150A 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 a demanding operating temperature range from -40°C to +180°C with low power losses and excellent heat dissipation.

The edge-wound coil of the device released today provides low DCR down to 0.25mΩ, which minimizes losses and improves rated current performance for increased efficiency. Compared to competing ferrite-based solutions, the IHDM-1008BC-30 offers 30% higher rated current and 30% higher saturation current levels at +125°C. The inductor's soft saturation provides a predictable inductance decrease with increasing current, independent of temperature.

With an operating voltage up to 350V, the device is 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.

The IHDM-1008BC-30's standard terminals are stripped and tinned for through-hole mounting. Designed with ER2519 powered iron core, the dimensions are 25 mm x 20 mm x 23 mm. Vishay can customize the device's mounting method, and performance, upon request.

Options include bare copper, surface-mount, and press fit. To reduce the risk of whisker growth, the inductor features a hot-dipped tin plating. The device is RoHS-compliant, halogen-free, and Vishay Green.

Samples and production quantities of the new inductor are available now, with lead times of 12 weeks. Pricing for U.S. delivery only is $7.39 per piece in 1000-piece quantities.
