Automotive-grade IHDM inductor is stable up to 150A
Powdered iron alloy core technology is at the heart of Vishay Intertechnology’s IHDM-1008BC-3A through-hole inductors. The IHDM automotive-grade edge-wound, through-hole inductor has rated current up to 150A for under-the-hood applications, says Vishay.
The Vishay Custom Magnetics devices provide stable inductance and saturation over a demanding operating temperature range from -40 to +180 degrees 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 mOhm, which minimises losses and improves rated current performance for increased efficiency. Compared to competing ferrite-based solutions, the IHDM-1008BC-3A offers 30 per cent higher rated current and 30 per cent higher saturation current levels at +125 degrees 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 350V, the IHDM-1008BC-3A is suitable 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.
Inductor dimensions are 25 x 20 x 23mm. 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 customise the device’s mounting method, and performance, upon request. Options include bare copper, surface-mount, and press fit. The device is RoHS-compliant and halogen-free.
Samples and production quantities are available now, with lead times of 12 weeks.
Vishay Intertechnology manufactures discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies and medical markets.
