The Type MG resistors utilise Caddocks Micronox® resistance film providing a number of performance features. This includes a wide resistance range to select from going up to 10,000 Megohms. They also have a wide voltage range available with some options going as high as 48,000 volts. They also feature an overvoltage capability of up to 150% of standard working voltage. This makes them very resilient and suitable for various applications including TWT amplifiers, X-ray systems, geophysical instruments, medical electronics, and many more.
