Vishay – New low-profile high-current inductors rated to 155C for autos and more (IHLP-2525CZ-5A)Sep 14 2012 - Passives [More Passives Articles]
Vishay has launched ten new IHLP low-profile, high-current inductors with extended temperature ranges to +155C for automotive and commercial applications. The new -51 and -5A series devices are offered in 2525, 3232, 4040, 5050, and 6767 case sizes with low profiles down to 3mm and a wide range of inductance values from 0.22µH to 33µH.
With a frequency range up to 1MHz, the devices serve as high-performing, space- and power-saving solutions for voltage regulator module (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 (POL) converters; distributed power systems; and field-programmable gate arrays (FPGAs).
The -51 and -5A series devices offer inductance values from 0.22µH to 33µH, saturation currents from 2.2A up to 87A, heat rating currents from 2.8A to 63A, and maximum DCR from 0.95mohm to 174mohm.
The new inductors handle high transient current spikes without hard saturation. Packaged in an RoHS-compliant, 100% lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the devices are specified for an operating temperature range of 55C to +155C, with high resistance to thermal shock, moisture, mechanical shock, and vibration, says the company.More news from Vishay
