    Where is a good place on the internet to buy capacitors? I've been looking all over for some 5.3 uf film capacitors and I can't find them in a 5.3 uf.

    Ebay, Mouser, AllElectronics, TaydaElectronics, just sort of calling out names, hope it helps.

    Mouser has a 4.7, and a 6.8, how exact do you need this to be?

    Oh, 5.6uF might be possible but I haven't seen a store that has it.

    5.3uF isn't a preferred value, so you'll have a hard time finding that exact value from a normal supplier. 4.7 or 6.3 uF would be easier. You probably need an X2 rated capacitor for this too.

    Where are you?

    I need this capacitor to replace a bad one in a fluorescent light fixture I have. What would a higher rated capacitor do? Would it be better? I have a few of these lights that need to be fixed. I figured it would be cheaper to replace the capacitors than the whole fixtures.

    You might have to add two capacitors in parallel such as a 4.7uF and a 0.6uF.
    Just Make sure that the voltage rating on both is equal or greater than the voltage rating of the capacitor you are replacing.

    If this is really a resonant type ballast I earlier described you must stick very close to the original capacitance.

    If this doesn't work I thing I would simply replace the whole ballast with a magnetic on or a transistor one.
