12NC INFORMATION FOR HISTORICAL CODING REFERENCE
The resistors have a 12-digit numeric code starting with 23
For 5 % tolerance:
• The next 7 digits indicate the resistor type and packing
• The remaining 3 digits indicate the resistance value:
- The first 2 digits indicate the resistance value
- The last digit indicates the resistance decade
For 1 % tolerance:
• The next 6 digits indicate the resistor type and packing
• The remaining 4 digits indicate the resistance value:
- The first 3 digits indicate the resistance value
- The last digit indicates the resistance decade
Last Digit of 12NC Indicating Resistance Decade
12NC Example
The 12NC for resistor type PR02 with Cu leads and a value
of 750  with 5 % tolerance, supplied on a bandolier of
1000 units in ammopack, is: 2306 198 53751.
