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.
