Vishay Expands IHLP Family of Low-Profile, High-Current Inductors


New Products Jun 08, 2006 by Jeff Shepard

Vishay Intertechnology, Inc. announced that it is extending its IHLP family of low-profile, high-current inductors with new devices in the 2525-size footprint offering a very low 3.0-mm height profile and inductance values from 22 µH down to 1.0 µH.

With the lowest dcR/µH for their respective package sizes, the new IHLP inductors serve as high-performing, space- and power-saving solutions for voltage regulator module (VRM) and dc-dc converter applications in end products including next-generation mobile devices; notebooks, desktop computers, servers, graphic cards, portable gaming devices, 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 Vishay Dale IHLP2525CZ11 inductors feature compact dimensions of 0.255 in. by 0.270 in. with a very low height profile of 0.118 in. They occupy the standard 2525 footprint shared by lower-profile IHLP devices while providing higher rated current and lower DCR values.

The new devices are specified for saturation currents ranging from 2.5 A to 9.5 A, typical dcR values ranging from 7.6 mΩ to 128.9 mΩ, and maximum dcR values ranging from 8.0 mΩ to 135.0 mΩ. Standard inductance tolerance is ±20%. The IHLP2525CZ11 inductors handle high transient current spikes without hard saturation and operate at a frequency up to 1 MHz. Packaged in an RoHS-compliant, 100% lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the new devices are 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 inductors are available now. Lead time for production quantities is eight to ten weeks. Pricing for U.S. delivery only in 10,000 -piece quantities is $0.32 per piece.
