** No longer in production. Small quanties still remain. Jelliff Alloy 800 is now available as a substitute for Alloy C/O/J **
JELLIFF Alloy C/O/J, with a resistivity 30% higher than any other alloy available, literally creates a new range of miniaturization for precision fixed and variable resistors. For a given volume, wire wound resistors can be one-fourth smaller, or one-third more resistance can be wound into a given volume than with 800 ohm alloys. Jelliff Alloy C/O/J exhibits a flat T/C curve of ±5 ppm over the temperature range of -55°C to 25°C and 25°C to 150°C. On a limited basis T/C's are available down to ±1 ppm over a shorter temperature range. Its low T/C coupled with its high stability allows resistor manufacturers to offer resistors exhibiting minimal resistance drift over long periods of time when subjected to load and temperature variations. C/O/J is available bare and insulated in diameters of 0.0031 to 0.0005. Economies and ordering convenience are afforded by its pricing structure of $/megohm.Bare wire will be provided unless other tolerances are required.This is sold by the pound, although some other companies sell it by length.
