Precision and Ultra-Precision Networks with Low Ratio TC

The T912 series from Caddock are resistor pairs and quads with ratio characteristics for precision analog circuits, with a resistance range from 1kΩ to 1MΩ. These resistors have an absolute tolerance of ±0.1% and a ratio tolerance from ±0.01% to ±0.1%. The absolute TCR (from -40°C to +85°C) values are: ±15 ppm/°C, ±25 ppm/°C, ±50 ppm/°C, and the ratio TCR (from -40°C to +85°C) values are: ±10 ppm/°C, ±25 ppm/°C and ±50 ppm/°C. The Caddock T912 series are constructed using the Tetrinox® resistance technology, in addition to the 14 standard equal value models of the Type T912 and T914, they can also be ordered with resistance ratios of 10:1, 9:1 or 1:1.
