Description
The VMN series from Caddock are transient tolerant voltage monitoring resistor networks, with a resistance range from 5kΩ to 4.99MΩ with a total resistance of 2MΩ or 5MΩ. These resistors have a ratio tolerance of ±0.02% or ±0.1%, the ratio TCR (from -40°C to +85°C) values are: ±5 ppm/°C and ±10 ppm/°C. The Caddock VMN series is manufactured with Tetrinox®, Caddock’s ultra-stable low-TC resistance film system. The Tetrinox® film system, combined with Caddock’s ceramic sandwich resistor network construction, provides
outstanding long-term stability in industrial applications with electrical surges, transient conditions, and high humidity exposure.
