| Type T912 and T914 Precision Resistor Networks Resistor Pairs and Quads with Ratio Characteristics for Precision Analog Circuits Type T912 and T914 Precision Resistor Networks are constructed with Caddock Tetrinox(R) resistance films to achieve the precise ratio performance and stability required by highly accurate amplifier circuits, voltage reference circuits, and precision bridge circuits. * Ratio Tolerance - from 0.1% to 0.01%. * Ratio Temperature Coefficient - 10 ppm/C, 5 ppm/C or 2 ppm/C. * Absolute Temperature Coefficient - 25 ppm/C. * Ratio Stability of Resistance at Full Load for 2,000 hours - within 0.01%. * Shelf Life Stability of Ratio for 6 Months - within 0.005%. Both the T912 and the T914 are available in 14 standard resistance values between 1K and 1 Megohm. Caddock's high thru-put manufacturing capability assures that prototype and large-volume production quantities are available either from stock or within 6 weeks after receipt of order. Standard Type T912 and Type T914 Precision Resistor Networks In addition to the 14 standard equal value models of the Type T912 and T914, the Type T912 can also be ordered with: * 10:1 Resistance Ratio - for use in amplifier gain-setting. * 9:1 Resistance Ratio - for use in voltage reference dividers. Ordering Information: Model Number Specifications: Absolute Tolerance: 0.1% for all resistors. Absolute Temperature Coefficient: 25 ppm/C referenced to +25C, R taken at 0C and +70C. Ratio Tolerance: Options for ratio tolerance are provided as shown in the Ordering Information panel. Ratio Temperature Coefficient: Options for ratio temperature coefficient are provided as shown in the Ordering Information panel. Voltage Rating: 30 volts DC or RMS AC applied to R1, R2, R3 and R4. Power Rating: 0.10 watt applied to R1, R2, R3 and R4 (not to exceed rated voltage). Package Power Rating: Type T912, 0.20 watt. Type T914, 0.40 watt. Storage Temperature: -55C to +105C. Insulation Resistance Between Isolated Pins: Pin 2 to Pin 3, Pin 4 to Pin 5, or Pin 6 to Pin 7, 1,000 Megohms, minimum.
