Precision and Ultra-Precision Networks with Low Ratio TC

The T914 series from Caddock are resistor 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 T914 series are constructed using the Tetrinox® resistance technology, in addition to the 14 standard equal values for the 2 resistor elements with a ratio of 1:1
