Space saving high-current inductor offers high-performance benefits

August 08, 2011 // By Paul Buckley
Vishay Intertechnology, Inc., has launched a new IHLP low-profile, high-current inductor in the 3232 case size with an ultra-low 3.0 mm profile. The compact IHLP-3232CZ-01 offers high efficiency with maximum DCR down to 1.61 mΩ and a wide range of standard inductance values from 0.22 µH through 10.0 µH.

With a frequency range up to 5 MHz, the IHLP-3232CZ-01 serves as a high-performing, space- and power-saving solution for voltage regulator module (VRM) and dc-to-dc converter applications in end products including next-generation mobile devices; notebooks, desktop computers, servers, graphic cards, portable gaming systems, personal navigation systems, personal multimedia devices, and automotive systems; low-profile, high-current power supplies and point of load (POL) converters; distributed power systems; and field-programmable gate arrays (FPGAs).

The IHLP-3232CZ-01 offers an inductance range from 0.22 µH to 10.0 µH, a saturation current range from 8.2 A up to 43.0 A, a heat rating current range from 4.7 A to 32.0 A, and maximum DCR from 1.61 mΩ to 71.20 m Ω.

The new inductor handles 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 device is specified for an operating temperature range of - 55 °C to + 125 °C, with high resistance to thermal shock, moisture, mechanical shock, and vibration.

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