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

The performance features of the Type MX Precision High

speciﬁcally developed for use in industrial and general purpose Voltage Resistors are:

high voltage systems. These resistors combine the proven

• Seven Models with Voltage Ratings from 7.5 KV to 48 KV.

performance of Caddock's Micronox resistance system

• 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%.

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 • Non-Inductive Design.

Precision High Voltage Resistors or Type MG Precision

• Resistance Range from 1 Megohm to 2,000 Megohms.
