The MX400 series from Caddock are cost effective high voltage resistors for industrial and general purpose applications, with a resistance range from 1MΩ to 1000MΩ and a maximum operating temperature of +175°C. These resistors have a maximum power rating of up to 10W (MX485 model) and tolerance of ±1.0% standard. The MX resistors combine the proven performance of Caddock's Micronox® resistance system with new cost-efficient design elements and the non-inductive serpentine pattern with a patented, high through-put screen printed silicone coating. These resistors are intended for the design of high voltage systems where the system is not exposed to full military or space grade operating conditions.

  • High ohmic high voltage axial leaded through-hole resistor
  • Utilises Caddock's Micronox® resistance film
  • Resistance values available between 1MΩ and 1000MΩ
  • TCR ±80 ppm/°C (between 0°C and +70°C)
  • Tolerance of ±1.0% standard
  • Maximum power rating of up to 10W (MX485 model)
  • Maximum operating temperature +175°C
  • Five sizes and power ratings

For full military or space grade operating conditions, we recommend Caddock's TG Low TC precision high voltage resistors or MG precision high voltage resistors.
