Series Cemented Wirewound Resistors Vishay BCcomponents 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: Last Digit of 12NC Indicating Resistance Decade RESISTANCE DECADE LAST DIGIT 0.1 TO 0.91 7 1 TO 9.1 8 10 TO 91 9 100 TO 910 1 1 K TO 9.1 K 2 10 k to 56 k 3 Ordering Example The ordering code of an AC01 resistor, value 47 k supplied in ammopack of 1000 units is: 2306 328 33473. - The first 2 digits indicate the resistance value. - The last digit indicates the resistance decade in accordance with the 12NC Indicating Resistance Decade table.
