HISTORICAL 12NC INFORMATION

• The resistors had a 12-digit numeric code starting with

2312

• The subsequent 4 digits indicated the resistor type,

specification and packaging; see the 12NC table

• The remaining 4 digits indicated the resistance value:

- the first 3 digits indicated the resistance value

- the last digit indicated the resistance decade in

accordance with resistance decade table
