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® 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 capabil-
ity 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
Specifications:
In addition to the 14 standard equal value models of the Type T912 and T914,
the Type T912 can also be ordered with:
Absolute Tolerance: ±0.1% for all resistors.
• 10:1 Resistance Ratio - for use in amplifier gain-setting.
• 9:1 Resistance Ratio - for use in voltage reference dividers.
referenced to +25°C, ΔR taken at 0°C and +70°C.
