New inductor series delivers high-temperature operation with no ageing

New Yorker Electronics now offers Vishay Dale’s new IHDM Series of edge-wound, through-hole inductors with an 1107 case size. The Vishay IHDM-1107BBEV-20 and IHDM-1107BBEV-30 inductors are perfect for DC-DC converters, inverters, differential mode chokes, filters for motor and switching noise suppression in high current, high-temperature applications, as well as industrial, medical, and defence systems. The inductors are provided with a choice of two core materials for optimised performance depending on the application.

The series offers a powdered iron alloy core technology with soft saturation current to 422A, providing stable inductance and saturation across a demanding operating temperature range, with low power losses and excellent heat dissipation. The edge-wound coil supplies low DCR down to 0.25mOhm, which minimises losses and improves rated current performance for increased efficiency. Compared to competing ferrite-based solutions, the devices provide 30% higher rated current and 30% higher soft saturation current levels that are stable at continuous operating temperatures to +180C. The inductors’ soft saturation offers a predictable inductance decline with increasing current, independent of temperature.

Standard terminals for the devices are stripped and tinned for through-hole mounting. Vishay can customise the devices’ performance – including inductance, DCR, rated current, and voltage rating. Customisable mounting options include bare copper, surface-mount, and press fit. The inductors feature a hot-dipped tin plating to reduce the risk of whisker growth. The devices are RoHS-compliant, halogen-free, and Vishay Green.
