Marking and Packing Information
The part will be marked
PFFM
YMDx
• Marking consists of the frequency “FF” which will be truncated to the first two digits due to package size.
• Date code consists of Year, Month and Day (see codes below)
• The x is an internal PLE production code
• Orientation of marking may be mixed on the tape
• Traceability of part is lost once removed from reel
