New Vishay Inductors Provide Saturation Currents up to 70 A and Typical DCR Values Down to 0.81 mΩ in 2525 Footprint

Devices Expand IHLP Family of Low-Profile, High-Current Inductors

MALVERN, PENNSYLVANIA - December 10, 2004 - Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has extended its IHLP family of low-profile, high-current inductors with two new devices offering inductance ranges of 0.1 µH to 2.2 µH (IHLP 2525EZ 05) and 3.3 µH to 10 µH (IHLP 2525EZ 01).

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-to-dc converter applications in end products including next-generation mobile devices; notebooks, desktop computers, and servers; 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 2525EZ 05 and IHLP 2525EZ 01 inductors measure 0.255 in. by 0.270 in. [6.47 mm by 6.86 mm] with a maximum height profile of 0.197 in. [5.0 mm]. Both 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 10 A to 70 A, typical DCR values ranging from 0.81 mΩ to 53.3 mΩ, and maximum DCR values ranging from 0.93 mΩ to 56 mΩ. The two inductors feature ±20% inductance tolerance.

Like other devices in the IHLP family of inductors, the IHLP 2525EZ 05 and IHLP 2525EZ 01 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.

Samples and production quantities of the new inductors are available now. Lead time for production quantities is six to eight weeks.
