Vishay Intertechnology announced a new series of high power, high current mica grid resistors in the standard mill bank size. The Milwaukee GREM resistors feature EDG technology for improvements in power capacity, weight, and watt density, with the same package size; offering designers a lower cost option to the standard stainless steel grid design.
These resistors 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. Moreover they are 30 % lighter than stainless steel grid resistors with the same power dissipation, making them ideal for applications such as load banks, dynamic braking, and motor control in low vibration industrial and alternative energy applications.
GREM resistors come in 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 resistors are now available with a lead time of four weeks.
