Type 1787 Current Sense Resistor Networks  
Page 1 of 2  
Accurate Current Sensing in Multi-Range Instrumentation  
Type 1787 Current Sense Resistor Networks utilize  
Caddock's Micronox® resistance films and advanced high  
thru-put laser manufacturing capabilities to achieve many  
vital advantages in precision current measurement circuits,  
including laboratory and bench-type digital instrumentation:  
• The thin-profile single-package configuration replaces as  
many as four discrete current sense resistors.  
• The monolithic construction and standardized lead spacing  
simplify installation.  
• Caddock Micronox® resistance films provide exceptional  
stability for improved long-term measurement accuracy.  
Twelve standard models in five network arrangements  
provide the specific accuracy and resistance values required  
for a wide range of current measuring instruments and  
circuits.  
Prototype quantities of most models of the Type 1787  
Current Sense Resistor Networks are available either from  
stock or within 6 weeks after receipt of order.
