ORDERING 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 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.
RESISTANCE DECADE LAST DIGIT
0.1 ΩTO 0.91 Ω7
1 Ω TO 9.1 Ω8
10 ΩTO 91 Ω9
100 Ω TO 910 Ω1
1 KΩ TO 9.1 KΩ2
10 kΩto 56 kΩ3
