Thanks Doug. This will help me understand capacitor values in the future. I now have an understanding of resistors, capacitors, ic`s (a little) and diodes. Transistors next😊
I have attached a picture of the site that confused me😎

Hi Peter,
I guess these are ceramic capacitors.
224 mean 22 x(10 to power 4) in Picofarad (pF) = 220000pF = 220nF. Or 0.22µF.
I.e. the '4' means the number of trailing zeroes.
Don't know where you 'looked up' the 1nF (1000puff as known in the trade!😮)
The leading 2s must appear in the final value!
Thus 1nF would be marked 102 and 10nF 103.
47nF should be marked 473.
After the value code there is usually letter indicating the value tolerance; J, K or M indicating ±5%, ±10% and ±20% respectively.
So, to finally answer your question 🙄; I would use the 47nF capacitors. (=0.047µF)
Older ones may be marked .047.
Cheers, Doug

Thanks Martin. I have seen this and it seems to be generally a standard layout. My main problem is whether the capacitor already fitted by Krick is adequate as the positive to negative contact suppressor is usually 47nf but the ones fitted by Krick seem to be only 1nf.😊

Hi mouldbuilder,
There is an article in the How to's on the home page (motor suppression)
I don't know if that will answer your question.

Martin.
