en.Wedoany.com Reported - Vishay Intertechnology, Inc. (NYSE: VSH) has launched four new IHDV series high-voltage power inductors supporting 1.5 kV isolation voltage, targeting next-generation automotive, energy, and industrial systems. These devices are available in two compact packages: the 0808 size measuring 20 mm x 14 mm x 14 mm, and the 1008 size measuring 25 mm x 20 mm x 23 mm. Among them, automotive-grade models IHDV-0808AC-3A and IHDV-1008BB-3A, as well as commercial-grade models IHDV-0808AC-30 and IHDV-1008BB-30, can operate stably in continuous high-temperature environments up to 180°C and feature soft saturation characteristics.

To achieve higher voltage withstand capability, Vishay has adopted PET plastic coil bobbins as insulators, enabling the devices to withstand 1.5 kV isolation voltage, thereby elevating the voltage capability beyond that of existing inductors (typically limited to 350 V). Utilizing iron powder alloy cores, this series of inductors maintains stable inductance under load, achieving efficient ripple current regulation; additionally, the devices can withstand transient surge currents up to five times the rated heating current.

In high-frequency filtering applications, the IHDV series exhibits outstanding impedance performance, significantly surpassing iron composite inductors of the same size. Specifically, the 0808 model provides an impedance of 1 kΩ at a peak frequency of 80 MHz; the 1008 model delivers 2.8 kΩ impedance at 25 MHz—a value that reaches three times that of similar devices at four times the frequency. Typical application scenarios include on-board chargers, battery charging circuits, power factor correction (PFC), and high-voltage DC battery filtering.

In terms of package design, the IHDV-0808AC-3A and IHDV-0808AC-30 adopt a compact surface-mount form factor, approximately one-third the size of the 1008 model; while the IHDV-1008BB-3A and IHDV-1008BB-30 utilize through-hole terminations, providing enhanced mechanical robustness in harsh environments. All four devices comply with RoHS, halogen-free, and Vishay Green standards, and are equipped with additional support pins to improve shock and vibration resistance. Furthermore, the automotive-grade models IHDV-0808AC-3A and IHDV-1008BB-3A have passed AEC-Q200 certification.

In terms of specifications, the 0808 model has dimensions of 20 mm x 14 mm x 14 mm, an inductance of 1.9 µH, a typical DC resistance of 1.3 mΩ, a maximum DC resistance of 1.5 mΩ, a typical rated heating current of 30.0 A (temperature rise ΔT approximately 40°C), a typical saturation current of 110 A (inductance drop approximately 30%), and a typical self-resonant frequency of 83 MHz. The 1008 model has dimensions of 25 mm x 20 mm x 23 mm, an inductance of 10 µH, a typical DC resistance of 2.7 mΩ, a maximum DC resistance of 2.9 mΩ, a typical rated heating current of 30.0 A, a typical saturation current of 68 A, and a typical self-resonant frequency of 22 MHz.
