Custom Low Ratio TC, Precision SIP Resistor Networks

The T1794 series from Caddock are custom low temperature coefficient precision SIP resistor networks, with a resistance range from 500Ω to 50MΩ. These resistors have an absolute tolerance range of between ±0.025% and ±1.0% and a ratio tolerance of between ±0.01% and ±1.0%. 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 T1794 series unique thin-profile, single-in-line edgemount package design allows the wide range of flexibility necessary to blend the performance of Tetrinox® resistance technology with particular circuit specifications to arrive at the final network package size, pin spacing and pin style.
