Vishay Intertechnology, Inc. introduced a new series of high power, high current mica grid resistors in the standard mill bank size. Offering designers a lower cost option to the standard stainless steel grid design, Vishay Milwaukee GREM resistors feature EDG technology for improvements in power capacity, weight, and watt density, while maintaining the same package size.

The devices released feature power of 8 kW at 40-degree C, which is 23 per cent higher than standard 6,500 W stainless steel grid resistors in the standard mill bank size. At the same time, GREM devices are 30 per cent lighter than stainless steel grid resistors with the same power dissipation, and offer a favourable price point. These specifications make the devices ideal for load banks, dynamic braking, and motor control in low vibration industrial and alternative energy applications.

GREM resistors feature a resistance range from 0.067 Ω to 24.273 Ω, with a tolerance of (±) 10 per cent, temperature coefficients down (±) 130 ppm/degree C, and currents from 18 A to 345 A. The devices offer high temperature operation to (+) 415-degree C.

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). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
