12NC INFORMATION FOR HISTORICAL CODING REFERENCE
• The resistors have a 12-digit ordering code starting with
23.
• The subsequent 7 digits indicate the resistor type,
specification and packaging.
• The remaining 3 digits indicate the resistance value:
- The first 2 digits indicate the resistance value.
- The last digit indicates the resistance decade in
accordance with resistance decade table.
Last Digit of 12NC Indicating Resistance Decade
12NC Example
The 12NC code of an AC01 resistor, value 47 Ω supplied in
ammopack of 1000 units is: 2306 328 33479.
