Help identify/ read part

[Crambone]

Hello, how do you look this part up from it’s markings? I believe it’s a Capacitor C3 as this board allows both types surface mount and standard to be used if desired. I can look it up on the schematic but would like to know how to look it up by its markings.
Or I could be totally wrong?

50E should be 50 Volts.
2R2 should make it a 2.2uF.
The black stripe indicates the negative terminal.
