Vishay Intertechnology Automotive Grade IHDM Inductor Offers Stable Inductance and Saturation at Temps to +180 °C and Current to 150 A
Featuring Powdered Iron Alloy Core Technology, This Edge-Wound, Through-Hole Device Provides Low DCR to Reduce Power Losses and Increase Efficiency
MALVERN, Pa., March 09, 2020 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new IHDM Automotive Grade edge-wound, through-hole inductor with rated current up to 150 A for under the hood applications. Featuring powdered iron alloy core technology, the Vishay Custom Magnetics IHDM-1008BC-3A 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 0.25 mΩ, which minimizes losses and improves rated current performance for increased efficiency. Compared to competing ferrite-based solutions, the IHDM-1008BC-3A offers 30 % higher rated current and 30 % higher saturation current levels at +125 °C and above. The inductor’s soft saturation provides a predictable inductance decrease with increasing current, with stable inductance across the operating temperature range.
With an operating voltage up to 350 V, the device is ideal for high current, high temperature power applications, including DC/DC converters, inverters, and filters for motor and switching noise suppression in hybrid, full-electric, and hydrogen fuel cell vehicles.
The IHDM-1008BC-3A’s standard through-hole mounting terminals are stripped and hot-dip tinned to reduce the risk of tin whisker growth, but Vishay can customize the device’s mounting method, and performance, upon request. Options include bare copper, surface-mount, and press fit. The device is RoHS-compliant, halogen-free, and Vishay Green.
