12NC INFORMATION

Components may be ordered by using either a simple cleartext ordering code, see “Type Description and OrderingCode” or Vishay BCcomponents’ unique 12NC.Numeric Ordering Code (12NC)

The resistors have a 12-digit Part Number starting with2312.

The subsequent 4digits indicate the resistor type,specification and packaging; see the 12NC Part Numbertable.

The remaining 4digits indicate the resistance value:–The first 3digits indicate the resistance value.

–The last digit indicates the resistance decade inaccordance with the 12NC Indicating ResistanceDecade table.
