All new edge-wound inductor offers stable inductance and saturation

Vishay Intertechnology, Inc. introduced 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 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 provides low DCR down to 0.25 mΩ, 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 350 V, the device is ideal for DC/DC converters, inverters, motor and switching noise suppression, and high power switchmode 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.
