Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new commercial IHLP® low profile, high current inductor that is the industry’s first composite inductor in the 19 mm by 19 mm by 7 mm 7575 case size. Offering high temperature operation to +155 °C for computer, telecom, and industrial applications, the Vishay Dale IHLP‑7575GZ-51 offers up to 30 % lower DCR and up to 35 % higher current ratings than devices in the 6767 case size, at a 50 % lower cost than devices in the 8787 case.
The inductor released today is optimized for energy storage in DC/DC converters up to 2 MHz and high current filtering applications up to the SRF of the inductor. Applications for the device include notebooks, desktops, and servers; low profile, high current power supplies; POL converters; battery-powered devices; and distributed power systems and FPGAs.
Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra low levels, the IHLP-7575GZ-51 offers high resistance to thermal shock, moisture, and mechanical shock, and handles high transient current spikes without saturation. The device is RoHS-compliant, halogen-free, and Vishay Green.
