MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has expanded its automotive component lineup with the release of two new high-current, through-hole inductors engineered for demanding automotive power applications. The IHDM-1107BBEV-2A and IHDM-1107BBEV-3A deliver improved efficiency, greater current-handling capability, and stability over extreme operating temperatures.
Developed by Vishay’s Inductors Division, the new devices are housed in a compact 1107 case size and feature edge-wound coil construction with a powdered iron alloy core. This design enables soft saturation currents up to 422 A and ensures stable inductance performance from -40 °C to +180 °C — a critical requirement for today’s electric and hybrid vehicle systems.
Compared to traditional ferrite-based inductors, the new models offer significant advantages at elevated temperatures. At +125 °C, the components deliver 30% higher rated current and 30% higher saturation current, enhancing reliability and power efficiency in high-heat environments such as engine compartments and battery enclosures.
The low direct current resistance (DCR), down to 0.22 mΩ, reduces power losses and improves overall system efficiency. A soft saturation curve ensures a predictable drop in inductance with rising current, making the devices suitable for mission-critical automotive electronics where performance predictability is essential.
With an isolation voltage rating of up to 350 V and AEC-Q200 qualification, the inductors target a range of automotive power electronics applications, including DC/DC converters, onboard chargers (OBC), inverters, domain control units (DCUs), and EMI filters. They are compatible with internal combustion, hybrid, and fully electric vehicles.
Standard versions come with stripped and tinned leads for through-hole mounting, though Vishay also offers custom configurations—including surface-mount and press-fit options—along with tailored performance specs for inductance, current rating, and voltage capacity. Both devices are RoHS-compliant, halogen-free, and feature hot-dipped tin plating to minimize whisker formation and meet Vishay Green standards.
The launch reflects Vishay’s broader strategy to support automotive electrification with robust, thermally resilient passive components that meet the evolving demands of modern powertrain and charging architectures.
