12NC INFORMATION
Components may be ordered by using either a simple clear
text ordering code, see “Type Description and Ordering
Code” or Vishay BCcomponents’ unique 12NC.
Numeric Ordering Code (12NC)
The resistors have a 12-digit Part Number starting with
2312.
The subsequent 4 digits indicate the resistor type,
specification and packaging; see the 12NC Part Number
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 Part Number of a UXA 0204 resistor, value 47 k
Ω
and
TCR 10 with ± 0.1 % tolerance, supplied on bandolier in a
box of 1000 units is: 2312 662 34703.
Note:
(1)
Readable 12NC coding of resistance values is restricted to values with three significant digits. For resistance values with more than three
significant digits, a non readable sequential number will be issued by the factory for each requested combination of resistance value and
tolerance.
