Vishay Extends IHLP Family of Current-Sensing Power Inductors With First Devices to Offer 5% DCR Tolerance

New Inductors Feature Very Low 3.0- and 3.5-mm Height Profiles, Saturation Currents up to 60 A, and Typical DCR Values Down to 1.4 mÙ

MALVERN, PENNSYLVANIA - April 9, 2004 - Vishay Intertechnology, Inc. (NYSE: VSH) today announced four new additions to the IHLP family of power inductors, which now includes the industry's first such devices available with a 5% DCR tolerance for current-sensing applications. These new series have been tested and approved by major IC manufacturers and several other customers.

With the lowest DCR/µH for their respective package sizes, the new IHLP-2525CZ-06, IHLP-2525CZ-07, IHLP-5050CE-06, and IHLP-5050CE-07 offer high-performing, space- and power-saving solutions for voltage regulator module (VRM) and dc-to-dc converter applications in end products including next-generation mobile devices; notebooks, desktop computers, and servers; low-profile, high-current power supplies and point of load (POL) converters; distributed power systems; and field programmable gate arrays (FPGAs).

New devices in the IHLP-2525CZ series feature compact dimensions of 0.255 in. by 0.270 in. [6.47 mm by 6.86 mm] with the lowest height profile - just 3.0 mm - available in this package footprint. The IHLP-2525CZ-06 and IHLP-2525CZ-07 are specified for saturation currents ranging from 7.0 A to 60 A and for typical DCR values ranging from 1.4 mÙ to 97.7 mÙ.

Available in a 0.508-in. by 0.520-in. [12.9-mm by 13.2-mm] package with a 3.5-mm height profile, the IHLP-5050CE-06 and IHLP-5050CE-07 are specified for saturation currents from 14 A to 51 A and for a DCR range of 1.85 mÙ to 30.86 mÙ.

The IHLP-2525CZ-06 and IHLP-5050CE-06 offer 10% DCR tolerance, while the IHLP-2525CZ-07 and IHLP-5050CE-07 provide an industry-first 5% DCR tolerance. The inductance range for IHLP-2525CZ-06 and IHLP-2525CZ-07 is 0.10 µH to 10 µH. The IHLP-5050CE-06 and IHLP-5050CE-07 have an inductance range from 0.60 µH to 10 µH.

These new power inductors from Vishay Dale handle high transient current spikes without saturation and operate over a frequency range up to 5 MHz. Packaged in a 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.

Because these devices include a current-sensing function, they allow designers to replace multiple parts with a single inductor, thereby lowering component count and costs.

Samples and production quantities of the new power inductors are available now. Lead time for production quantities is 6 to 11 weeks. Pricing for U.S. delivery only in 10,000-piece quantities starts at $0.82.

Vishay, a Fortune 1,000 Company listed on the NYSE, is one of the world's largest manufacturers of discrete semiconductors (diodes, rectifiers, transistors, optoelectronics, and selected ICs) and passive electronic components (resistors, capacitors, inductors, and transducers). The Company's components can be found in products manufactured in a very broad range of industries worldwide.
