Inductor provides low DCR to reduce power losses and increase efficiency

Vishay Intertechnology offers the new IHDM edge-wound, through-hole inductor with rated current up to 150A for industrial and defence applications. Providing a powdered iron alloy core technology, the Vishay Custom Magnetics IHDM-1008BC-30 offers stable inductance and saturation over a exacting operating temperature range from -40C to +180C with low power losses and outstanding heat dissipation.


The edge-wound coil of the device produces low DCR down to 0.25mOhm, which reduces losses and increases rated current performance for enhanced efficiency. Compared to competing ferrite-based options, the device provides 30% higher rated current and 30% higher saturation current levels at +125C. The inductor's soft saturation offers a predictable inductance decrease with increasing current, independent of temperature.


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


The device's standard terminals are stripped and tinned for through-hole mounting. Created with ER2519 powered iron core, the dimensions are 25mm x 20mm x 23mm. The company can customise the device's mounting method, and performance, upon request. Options include bare copper, surface-mount, and press fit. To decrease the risk of whisker growth, the inductor offers a hot-dipped tin plating. The device is RoHS-compliant, halogen-free, and Vishay Green.
