AC.. 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.
