CADDOCK 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.
