New low-profile, high-current inductors support extended temperature ranges to +155 degrees C

September 13, 2012 // By Paul Buckley
Vishay Intertechnology, Inc., has launched 10 new IHLP low-profile, high-current inductors with extended temperature ranges to + 155 °C for automotive and commercial applications.

The new − 51 and − 5 A series devices are offered in 2525, 3232, 4040, 5050, and 6767 case sizes with low profiles down to 3.0 mm and a wide range of inductance values from 0.22 to 33 µH.

With a frequency range up to 1 MHz, the devices released today 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 0.22 µH to 33 µH, saturation currents from 2.2 A up to 87.0 A, heat rating currents from 2.8 A to 63.0 A, and maximum DCR from 0.95 mΩto 174.0 mΩ.

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 − 55 °C to + 155 °C, with 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.
