What if a single inductor could withstand 1.5kV, survive 180°C heat, and suppress high frequency noise in next generation EVs and chargers?
Vishay Intertechnology has introduced a new series of high voltage power inductors designed for automotive, industrial, and energy applications. The IHDV family is engineered for systems requiring isolation voltages of up to 1.5kV, a significant increase over the voltage ratings typically supported by conventional power inductors.
The devices are intended for applications such as onboard EV chargers, battery charging circuits, power factor correction systems, and high voltage DC battery filtering. These applications increasingly require components capable of handling higher power densities while maintaining stable operation under demanding electrical and environmental conditions.
According to the company, the inductors achieve their higher isolation capability through a PET plastic coilform insulation structure. They also incorporate a powdered iron alloy core that provides soft saturation characteristics, helping maintain inductance stability under varying load conditions and during transient current surges.
For high frequency filtering applications, the inductors offer impedance values exceeding 1kΩ, enabling effective suppression of unwanted noise generated by modern power conversion equipment. The devices are also rated for continuous operation at temperatures up to 180°C, making them suitable for harsh operating environments.
The series is available in compact 0808 and 1008 package sizes and includes both automotive and commercial variants. Automotive versions are qualified to AEC-Q200 standards, while additional support pins are designed to improve resistance to shock and vibration in rugged applications.
Samples and production quantities of the inductors are available, with the company targeting next generation automotive, energy storage, and industrial power systems.
