I am pretty sure you have the wrong component- capacitors are really weird- in the US the label "mf" of "mfd" is a micro farad- the picture above is something far larger than 3 mfd- the ceramic disc caps most often suggested are quite small... smaller than a smashed pea!
Lets wait to see what BJM-Maxx says as they know this like the back of their hand and I am not an EE, maybe this is something else and I am confused!!!
