Vishay introduces automotive grade IHSR high temperature inductors for multiphase power filtering

     Vishay Intertechnology, Inc. has announced the launch of its new IHSR high temperature inductor, IHSR-2525CZ-5A, in 7.4mm x 6.6mm x 3.0mm 2525 dimensions in AEC-Q200. Designed for multiphase high-current power supplies and filters, the Vishay Dale IHSR-2525CZ-5A offers a 50% reduction in internal DC resistance (DCR) compared to conventional power inductors and offers excellent value saturation stability over the entire operating temperature range compared to ferrite solutions. Suitable for car engine compartment and advanced driver assistance system (ADAS).

     The recently released automotive grade inductors with frequencies up to 10MHz are particularly suitable for DC/DC converter energy storage and for high-current filtering below the inductor self-resonance frequency (SRF). The device operates at +155 °C and is suitable for filtering and DC/DC conversion. Applications include engine and transmission control units, ADAS microcontrollers, entertainment/navigation systems, as well as engine noise suppression, wipers, electric mirrors and seats, heated ventilators and more.

     The IHSR-2525CZ-5A has a typical DC resistance as low as 0.38mΩ and an inductance value of 0.056µH. The IHSR-2525CZ-5A has a higher current density than other similar technologies. The 3mm height enables the finished product design to be more lightweight. Inductor package is 100 % lead free (Pb) shielded composite structure, noise reduction to ultra-low levels, with high thermal shock resistance, moisture resistance, mechanical vibration resistance, can handle high transient current spikes without saturation. The device meets RoHS and Vishay green standards and is halogen-free.
