New Vishay Intertechnology Mica Grid Resistors Offer Improved Power Capacity, Weight, and Watt Density Over Stainless Steel Devices

For Load Banks, Dynamic Braking, and Motor Control, Resistors Feature Power of 8 kW in Standard Mill Bank Size

MALVERN, Pa. — Aug. 6, 2018 — Vishay Intertechnology, Inc. (NYSE: VSH) today 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 today feature power of 8 kW at 40 °C, which is 23 % higher than standard 6500 W stainless steel grid resistors in the standard mill bank size. At the same time, GREM devices are 30 % lighter than stainless steel grid resistors with the same power dissipation, and offer a favorable 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 %, temperature coefficients down ± 130 ppm/°C, and currents from 18 A to 345 A. The devices offer high temperature operation to +415 °C.

Samples and production quantities of the GREM series are available now, with lead times of four weeks. Pricing for U.S. delivery only ranges from $300 to $600 per resistor.
