Accurate Current Sensing in Multi-Range Instrumentation
T*e 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-t*e di*al 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.
Protot*e quantities of most models of the T*e 1787 Current Sense Resistor Networks are available either from stock or within 6 weeks after receipt of order.
Absolute Tolerance:
Tolerance of RA, RB, RC, or RD when measured in accordance with proper Figure No.
Absolute Temperature Coefficient: Temperature coefficient of RA, RB, RC, or
RD from 0°C to +70°C, referenced to +25°C.
Load Life: Stability of RA, RB, RC, or RD with full power applied individually for 2,000 hours at +70°C.
Shelf Life: Stability of RA, RB, RC, or RD for
six months at shelf conditions.
Storage Temperature: -55°C to +85°C.
