(2) Last 3 digits available on request.
(3) Radial parts with tin plated copper leads.
12NC INFORMATION
• The resistors have a 12-digit ordering code starting with
23.
• The subsequent 7 digits indicate the resistor type,
specification and packaging; see the 12NC Ordering Code
table.
• 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 the 12NC Indicating Resistance
Decade table.
Last Digit of 12NC Indicating Resistance Decade
Ordering Example
The ordering code of an AC01 resistor, value 47 kΩ supplied
in ammopack of 1000 units is: 2306 328 33473.
Product specifications deviating from the standard values
are available on request.
