DOC Resistor Pairs and Quads with Ratio Characteristics for Precision Analog Circuits
Type T912 and T914 Precision Resistor Networks are constructed with Cad d ock Tetrinox ® resistan
ce fi lms to achieve the precise ratio performance and stability required by highly accurate amplifi er circuits, voltage reference circuits, and precision bridge circuits.• Ratio Tolerance - from 0.1% to 0.01%.• Ratio Temperature Coeffi cient - 10 ppm/°C, 5 ppm/°C or 2 ppm/°C.• Absolute Temperature Coeffi cient - 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.
Specifi cations:
Absolute Tolerance: ±0.1% for all resistors.Absolute Temperature Coeffi cient: 25 ppm/°C referenced to +25°C, ΔR taken at 0°C and +70°C.Ratio Tolerance: Options for ratio tolerance are provided as shown in the Ordering Information panel.
Ratio Temperature Coeffi cient: Options for
ratio temperature coefficient are provided as shown in the Ordering Information panel.
Voltage Rating: 30 volts DC or RMS AC ap p lied to R 1, R 2, R 3 and R 4.Power Rating: 0.10 watt applied to R 1, R 2, R 3 and R 4 (not to exceed rated voltage).
Package Power Rating: Type T912, 0.20 watt. Type T914, 0.40 watt.
Storage Temperature: -55°C to +105°C.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.
Dielectric Strength Between Isolated Pins: 50 volts RMS AC.
Custom Model T912 and T914 Precision Resistor Networks
三自由度For applications requiring non-standard resistance values, the T912 and T914 custom confi gurations can include these special features:• Mixed resistance values with a maximum ratio of 250-to-1. (Example: 1 Megohm and 4 K)• Absolute TC as low as 15 ppm/°C.• Ratio TC as low as 2 ppm/°C.• Custom voltage ratings.
• Matched resistors of any special value between 1 K and 2 Megohms.
Contact our Applications Engineering for performance, price, and availability of these
custom resistor networks.
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 amplifi er gain-setting.
