Vishay Expands IHLP Family of Low-Profile, High-Current Inductors With New Devices Offering Saturation Currents up to 12 A and Typical DCR Values Down to 3.4 mΩ in 2525 Footprint

  MALVERN, PENNSYLVANIA Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it is extending its IHLP family of low-profile, high-current inductors with new devices in the 2525-size footprint offering inductance values from 10 H down to 0.56 H. With the lowest DCR/H 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, 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 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]. 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 4.5 A to 12 A, typical DCR values ranging from 3.4 m to 67.9 m, and maximum DCR values ranging from 3.6 mΩ to 71.3 mΩ. Standard inductance tolerance is 20 %.

Like other devices in the IHLP family of high-current inductors, the IHLP-2525EZ-01 devices handle high transient current spikes without hard saturation and operate at a frequency under 1MHz. 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 six to eight weeks.
