Type MX Precision High Voltage Resistors Cost Effective High Voltage Resistors for Industrial and General Purpose Applications The Type MX Precision High Voltage Resistors were specifically developed for use in industrial and general purpose high voltage systems. These resistors combine the proven performance of Caddock's Micronox (R) resistance system with new cost efficient design elements. 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. For full military or space grade operating conditions, we recommend Caddock's Type TG Low TC Precision High Voltage Resistors or Type MG Precision High Voltage Resistors. The performance features of the Type MX Precision High Voltage Resistors are: * Five Models with Voltage Ratings from 7.5 KV to 32 KV. * Temperature Coefficient: 80 ppm/C from 0C to +70C. * Load Life Stability of 0.50% per 1,000 hours. * Resistance Tolerance: 1% Standard. * Non-Inductive Design. * Resistance Range from 1 Megohm to 1,000 Megohms.

The alignment of the gap in the coating pattern with the gap in the serpentine resistor pattern provides a complete encapsulation of the resistor element. The cap and lead assemblies are pressed onto the resistor core, finishing the resistor and providing rugged terminal attachment.
