If we look at the manufacturer part numbers for these two examples
251R14S680JV4T or 251R15S120JV4E
The endings are either E or T for the suffix (these are the most common). These suffixes call out the packaging that the manufacturer uses.
E stands for a 7" tape and reel of embossed tape.
T stands for a 7" tape and reel of paper tape.
The manufacturer datasheet has the full part numbering breakdown for their capacitors including more options for packaging and other specifications in the parts.
