22 Type MX Lab Grade Precision High Voltage Resistors High Voltage Resistors for Laboratory and Industrial Applications The Type MX Lab Grade Precision High Voltage Resistors were specifically developed for use in high performance laboratory and industrial high voltage systems. These resistors combine the proven performance of Caddock's Micronox 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 Lab Grade Precision High Voltage Resistors are: Seven Models with Voltage Ratings from 7.5 KV to 48 KV. Temperature Coefficient: 80 ppm/C from OC to +70C. * 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. Ordering Information: MX485 -100M - 1. 0% Model Number: Tolerance . Resistor Value: .
