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
