HISTORICAL 12NC INFORMATION

 The resistors had a 12-digit code starting with 2312

 The subsequent 4 digits indicated the resistor type,

specification and packaging; see the 12NC table

 The remaining 4 digits indicate the resistance value:

- The first 3 digits indicated the resistance value

-

The last digit indicated the resistance decade in

accordance with the resistance decade table

RESISTANCE DECADE

Historical 12NC Example
