12NC INFORMATION

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

2312.

• The subsequent 4 digits indicate the resistor type,

specification and packing; see the 12NC Ordering Code table.

• The remaining 4 digits indicate the resistance value:

– The first 3 digits indicate the resistance value.

– The last digit indicates the resistance decade in

accordance with the 12NC Indicating Resistance

Decade table.

Last Digit of 12NC Indicating Resistance Decade
