Marking of capacitors

"C","D","E","X" case sizes marking

"B" case size marking

1 – Positive terminal (color stripe)
2 – Rated capacitance, pF
3 – Capacitance multiplier code
4 – Product code (only “77” is marked, stripe unavailability is acceptable)
5 – Rated voltage, V
6 – Production date code
7 – Trade mark

There is only polarity marking (color stripe) on “A” case size capacitors.
