Vishay Intertechnology has introduced a commercial IHLP low profile (7mm) high current composite Inductor in 7575 (19 x 19mm) case size, claiming it to be an industry first.
Operating at up to 155°C for computer, telecom and industrial applications, the IHLP 7575GZ-51 offers up to 30% lower dc resistance and up to 35% higher current compared with devices in 6767 cases, and 50% lower cost than devices 8787 devices, according to the company.
It is optimised for energy storage in dc-dc converters up to 2MHz, and high current filtering applications (up to the self-resonant frequency).
Construction is a 100 % Pb-free shielded composite “that reduces buzz noise to ultra low levels”, said the company, which also claims high resistance to thermal shock, moisture, and mechanical shock.
The device is RoHS-compliant, halogen-free and ‘Vishay Green’.
Use if foreseen in notebooks, desktops, servers, point-of-load converters, distributed power systems and with FPGAs.
