MALVERN, PENNSYLVANIA - January 17, 2000 - Vishay Intertechnology, Inc. (NYSE: VSH), today announced the release of three new series of inductors/transformers in surface-mount, toroidal packages. Offering designers a choice of Kool-Mu®, powdered iron, or MPP cores, the new Vishay Dale LPT-3535 series minimizes EMI radiation in dc-to-dc converter, common mode choke, and isolation transformer circuits in a broad range of electronic systems. Typical applications for the new components will include stand-alone power supplies, automotive, military and aerospace applications, consumer electronics, and test and measurement devices.

With a diameter of 8.93 mm (0.35 inches) and a height profile of 6.35 mm (0.235 inches), the new inductors/transformers offer designers a choice of 14 inductance values from 1 microhenry to 330 microhenrys. DC resistance is as low as 4 milliohms for a 1-microhenry component with a powdered iron core, with maximum current values as high as 6.45 A. Inductance tolerance is specified at ±15% for all devices.

"These new inductors/transformers are an excellent choice for high-efficiency dc-to-dc converters in portable products where their compact, toroidal design will save space without compromising EMI/EMF performance," said Michael Husman, Director, Product Marketing.

Two separate windings on each component allow connections to be made in series or in parallel. Half and quarter-height devices, in addition to custom versions, are available on request from Vishay.

A high-temperature shell design makes the new LPT-3535 series ideal for infrared (IR) reflow applications, while pick-and-place-compatible tape-and-reel packaging makes the new components easy to use with high-speed assembly equipment.

Samples and production quantities of the new LPT-3535 inductors are available now, with lead times of eight weeks for larger orders.

Vishay Intertechnology, Inc., a Fortune 1000 Company listed on the NYSE (VSH), is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors).
