Pb-free JEDEC designator for Matte Tin (Sn)
Note: For very small packages with no room for the Pb-free JEDEC designator
, the marking will only appear on the outer carton or reel label.
Note: In the event the full Microchip part number cannot be marked on one line, it will
be carried over to the next line, thus limiting the number of available
characters for customer-specific information.
