Rhopoint precision resistor networks T912 and T914 are constructed with Caddock Tetrinox resistance films to achieve the precise ratio performance and stability required by highly accurate amplifier circuits, voltage reference circuits and precision bridge circuits.
The T912 and T914 precision resistor networks are built with Caddock Tetrinox® resistance films to deliver accurate ratio performance and stability for high‑accuracy amplifier, voltage reference, and bridge circuits. Both types are offered in 14 standard resistance values from 1 kΩ to 1 MΩ, with optional 9:1 and 10:1 ratios for gain‑setting and reference applications.
Key specifications include ratio tolerances as low as 0.01%, temperature coefficients as low as 2 ppm/°C, voltage rating of 30 V DC or RMS AC, and power ratings of 0.20 W (T912) and 0.40 W (T914). Custom resistance values, mixed ratios up to 250:1, and special voltage ratings are also available on request.
