Type MX Precision High Voltage Resistors Cost Effective High Voltage Resistors for Industrial and General Purpose Applications T he Type MX Precision High Voltage Resistors were specifically developed for use in industrial and general purpose high voltage systems. These resistors combine the proven p erformance of Caddock's Micronox ® r esistance system w ith new cost efficient design elements. These resistors are intended for the design of high voltage systems where t he system is not exposed to full military or space grade operating conditions. For full military or space grade operating c onditions, we recommend Caddock's Type TG Low TC Precision High Voltage Resistors or Type MG Precision High Voltage Resistors. MX431 The performance features of the Type MX Precision High Voltage Resistors are: • Seven Models with Voltage Ratings from 7.5 KV to 48 KV. • Temperature Coefficient: 80 ppm/°C from 0°C to +70°C. • Load Life Stability of 0.50% per 1,000 hours. • Resistance Tolerance from ±0.1% to ±10%. • Non-Inductive Design. • Resistance Range from 1 Megohm to 2,000 Megohms.

The alignment of the gap in the coating pattern with the gap i n 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. Resistance Tolerance: ±1%, ±2%, ±5%, or ±10% (tolerance to ±0.5%, ±0.25%, or ±0.1% on special order). Temperature Coefficient: 80 ppm/°C referenced to +25°C, ΔR taken at 0°C and +70°C.
