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
12NC Example
The 12NC code of a MBA 0204 resistor, value 47 k
and TC
25 with
±
0.1 % tolerance, supplied on bandolier in a box of
5000 units is: 2312 906 74703.
