TT Electronics/IRC PFC series resistors - 4013 suffix

When looking at TT Electronics/IRC’s PFC series resistors, you may sometimes see the part number with a “4013” suffix and this additional suffix code that is not included in the ordering information (such as PFC-W1206LF-03-2003-B-4013).

  • “-4013” is defined as supplier internal factory code for IRC

These 3 or 4 digit suffixes on some IRC part numbers are internal IRC specification numbers and have no bearing on the part’s parameters and/or characteristics.
