Vishay Intertechnology, Inc. has introduced two new IHDM edge-wound, through-hole inductors in the 1107 case for commercial applications with soft saturation current to 422 A.
Featuring a powdered iron alloy core technology, the Vishay Custom Magnetics IHDM-1107BBEV-20 and IHDM-1107BBEV-30 provide stable inductance and saturation over a demanding operating temperature range from -55° to +180 °C with low power losses and excellent heat dissipation.
The edge-wound coil 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-1107BBEV-20 and IHDM-1107BBEV-30 offer 30% higher rated current and 30 % higher soft saturation current levels that are stable at continuous operating temperatures to +180° C. The inductors’ soft saturation provides a predictable inductance decrease with increasing current, independent of temperature.
With an operating voltage up to 350 V, the devices are ideal for DC/DC converters, inverters, differential mode chokes, and filters for motor and switching noise suppression in high current, high-temperature applications — including industrial, medical, and military systems. The inductors are available with a selection of two core materials for optimized performance depending on the application.
Standard terminals for the IHDM-1107BBEV-20 and IHDM-1107BBEV-30 are stripped and tinned for through-hole mounting. Vishay can customize the devices’ performance — including inductance, DCR, rated current, and voltage rating upon request. Customizable mounting options include bare copper, surface-mount, and press fit.
To reduce the risk of whisker growth, the inductors feature a hot-dipped tin plating. The devices are RoHS-compliant, halogen-free, and Vishay Green.
