Typical model number
Special tolerances are available upon request. Consult factory for special resistance tolerances, nonstandard resistances and/or non-standard temperatures.
*The zero-power resistance at 77°F (25°C), expressed inΩ, is identified by a
three digit code number. The first two digits represent significant figures, and
the last digit specifies the number of zeros to follow. Example: 10k Ω= “103”.
The standard resistance values are from the 24-Value series decade as specified
in Military Standard MS90178.
