MALVERN, PA — Vishay Intertechnology (NYSE: VSH) has introduced a new family of high-voltage power inductors designed for electric vehicles, energy infrastructure, and industrial power systems, expanding its portfolio as demand grows for components capable of handling higher voltages and temperatures.
The company this week launched the first four devices in its IHDV series, engineered for applications requiring isolation voltages of up to 1.5 kilovolts — more than four times the voltage capability typically offered by conventional inductors.
The new products include two automotive-grade devices, the IHDV-0808AC-3A and IHDV-1008BB-3A, alongside commercial versions, the IHDV-0808AC-30 and IHDV-1008BB-30.
The components are aimed at next-generation power electronics used in on-board vehicle chargers, battery-charging systems, power-factor-correction circuits, and high-voltage DC battery filtering applications.
According to Vishay, the inductors combine continuous operating temperatures of up to 180 degrees Celsius with soft saturation characteristics designed to maintain inductance stability under load while tolerating transient in-rush currents up to five times their rated current.
The devices incorporate a PET plastic coilform insulator that enables the higher isolation voltage rating, while a powdered iron alloy core supports performance in demanding power-conversion environments.
For high-frequency filtering applications, the company reported that the 0808 models provide impedance of 1 kilo-ohm at 80 MHz, while the larger 1008 devices deliver 2.8 kilo-ohms at 25 MHz.
Vishay is offering the products in two package sizes. The smaller surface-mount 0808 design occupies roughly one-third the volume of the larger 1008 package, while the larger through-hole version is intended for applications requiring increased mechanical durability.
All four devices include additional support pins designed to improve resistance to shock and vibration. The automotive versions are qualified to the AEC-Q200 automotive reliability standard.
The launch expands Vishay’s portfolio of passive components as manufacturers of electric vehicles, renewable energy systems, and industrial automation equipment seek components capable of supporting higher-voltage architectures and increasingly demanding operating conditions.
