Vishay Intertechnology Unveils High Voltage IHDV Inductors for Automotive and Commercial Applications
1. Introduction of Innovative Inductor Line
On June 18, 2026, Vishay Intertechnology, Inc. (NYSE: VSH) announced the launch of its new IHDV line of high voltage power inductors, catering to the evolving demands of next-generation automotive, energy, and industrial systems. The initial offerings in this lineup include four new devices that promise to elevate the performance standards for high-voltage applications, boasting an impressive isolation voltage capability of 1.5 kV.
2. Compact and Efficient Design
The IHDV inductors are available in two compact case sizes: the 0808 model measuring 20 mm x 14 mm x 14 mm, and the 1008 model measuring 25 mm x 20 mm x 23 mm. These designs are engineered not only for efficiency but also for high temperature operation, sustaining temperatures up to 180 °C. The automotive-grade variants, IHDV-0808AC-3A and IHDV-1008BB-3A, alongside the commercial versions, IHDV-0808AC-30 and IHDV-1008BB-30, are tailored for applications requiring both robust performance and reliability.
3. Enhanced Voltage Capabilities
Breaking away from the limitations of existing inductors, which typically support voltages up to 350 V, Vishay’s new IHDV devices feature a PET plastic coilform insulator designed to withstand the rigors of 1.5 kV isolation voltage. This advancement is made possible through the integration of a powdered iron alloy core, enhancing the inductors' capacity to maintain stable inductance under load. Furthermore, they can tolerate transient in-rush currents up to five times their heat rating current, making them ideal for demanding applications.
4. Superior Performance Metrics
The IHDV inductors excel in high-frequency filtering, demonstrating significantly higher impedance compared to similarly sized iron composite inductors. The 0808 models achieve an impressive impedance of 1 kΩ at a peak frequency of 80 MHz, while the 1008 models reach 2.8 kΩ at 25 MHz—three times the impedance of comparable inductors at four times the frequency. This performance is critical for applications such as on-board chargers, battery charging circuits, power factor correction (PFC), and high voltage DC battery filtering.
5. Design Advantages and Compliance
The compact IHDV-0808AC-3A and IHDV-0808AC-30 offer a surface-mount footprint that is roughly one-third the volume of their larger counterparts. In contrast, the IHDV-1008BB-3A and IHDV-1008BB-30 feature through-hole terminations that provide maximum mechanical strength, particularly in rugged environments. All four inductors are RoHS-compliant, halogen-free, and classified as Vishay Green, with added support pins to enhance their resistance to shock and vibration. Notably, the automotive versions are AEC-Q200 qualified, confirming their suitability for automotive applications.
