Vishay Intertechnology Inc. introduces 10 new IHLP low-profile, high-current inductors in its -51 and -5A series.


The devices operate from -55°C to +155°C, and come in 2525, 3232, 4040, 5050, and 6767 case sizes with profile as low as 3mm, and inductance values ranging from 0.22µH to 33µH.

The devices tip 1MHz frequency range, and are said to be suited for use in voltage regulator modules (VRM) and DC/DC converter applications. AEC-Q200 qualified, the IHLP-2525CZ-5A, IHLP-3232DZ-5A, IHLP-4040DZ-5A, IHLP-5050FD-5A, and IHLP-6767GZ-5A are designed for high-temperature automotive applications, including engine and transmission control units, diesel injection drivers, entertainment and navigation systems, noise suppression for motors, and power seats and mirrors.

The IHLP-2525CZ-51, IHLP-3232DZ-51, IHLP-4040DZ-51, IHLP-5050FD-51, and IHLP-6767GZ-51 are intended for high-temperature commercial applications, including next-generation mobile devices; notebooks, desktop computers, servers, graphic cards, portable gaming devices, personal navigation systems, and personal multimedia devices; low-profile, high-current power supplies and point of load converters; distributed power systems; and FPGAs.

The devices also offer saturation currents from 2.2A up to 87A, heat rating currents from 2.8A to 63A, and maximum DCR from 0.95mΩ to 174mΩ.

The inductors handle high transient current spikes without hard saturation. Packaged in an RoHS-compliant, Pb-free shielded, composite construction that reduces buzz noise to ultra-low levels, the devices claim high resistance to thermal shock, moisture, mechanical shock, and vibration.

Samples and production quantities of the new inductors are available now, with lead times of 10 to 12 weeks for large orders.
