Despite my efforts to check and double check each component before installing it on to the board I went an soldered a capacitor in the wrong place. Anyway, I was able to successfully remove it without damaging the board but I did wreck the capictor. So, I need to replace it. But where can I buy just one capictor?

I need a 22PF 200V capacitor with the code 399-1908-ND and 220 marking. Do normal shops like Maplin sell such things?

My local B&Q has got them but you might want to go here 10 for 50p?>

I would imagine maplin would have then. Have a search on there website.

If you need to remove components with low risk of damage to component or PCB you will find that a 'solder sucker' is just the ticket.
