Caddock Tetrinox® resistance films enable the necessary ratio performance and stability to be achieved in precision resistor networks, as required by high-end analogue circuits such as highly accurate amplifiers as well as voltage reference and precision bridge circuits. Resistors pairs and quads are matched with the approriate ratio characteristics (ratio tolerance from 0.1 to 0.01%, ratio temperature coefficient at 10, 5 and 2ppm/°C) to give the requisite precision.
