Type 1789 Custom Low Resistance Value
Precision SIP Resistor Networks
Where high accuracy and low resistance
values must be combined - as in high accuracy
current measurement circuitry - Kelvin
ter mi na tions can be provided for low resistance
values to minimize lead resistance errors.
The optimum design of Type 1789 Custom
Low Resistance Value Precision SIP Resistor
Networks is best achieved when the
performance of Micronox® resistance film
technologies is blended with particular circuit
specifications and the unique thin-profile,
single-in-line package design to arrive at the
fi nal network package size, pin spacing, and pin
style.
Applications for the Type 1789 Custom Low
Resistance Value Precision SIP Resistor
Networks include:
• Current Summing Networks
• Precision Termination Networks
• Precision Current Sense Resistor Networks
• Impedance Matching Networks
Low Resistance Custom Resistor Networks with Values as Low as 0.5 ohm
The design fl exibility achieved by Caddock's advanced resistance
fi lm technologies is extended to low resistance values in precision
resistor networks through the application of Caddock's Micronox®
resistance fi lms.
By applying this technology to the low-profi le, single-in-line package
confi guration, the Type 1789 Custom Low Resistance Value Precision
SIP Resistor Networks are available with a combination of features,
which include:
• Resistance Values: from 0.5 ohm to 10,000 ohms.
• Absolute Tolerances: ±1.0%, ±0.50%, ±0.25%, ±0.20%,
±0.10%, or ±0.05%.
• Ratio Tolerances: ±1.0%, ±0.50%, ±0.25%, ±0.20%, ±0.10%,
or ±0.05%.
• Absolute Temperature Coeffi cient: 100 ppm/°C,
80 ppm/°C, or 50 ppm/°C from 0°C to +70°C.
• Ratio Temperature Coeffi cient: 80 ppm/°C, 50 ppm/°C,
25 ppm/°C, or 15 ppm/°C from 0°C to +70°C.
• Power Rating: 100 mW to 2 Watts per resistor.
