Spark for split second, capacitor burnt out… is this fixable? : r/fpv
On the other hand, I would be more worried about the cause of the capacitor burning itself. It could be manufacturing problem, it could be that you wired it wrong, I can''t tell, since you didn''t specify how exactly did it happen or if the board is new/older so we could better diagnose what exactly is wrong.
How can I lower the chance of burning out capacitors?
However these keep failing, every one burning out a (large) electrolytic capacitor (after say 1 years'' service). Oddly these boards vary slightly, some have one cap, some 2, but invariably this is the part(s) that fails. The boards with 1 cap are rated at 22µF 450v ...

What is a Capacitor Bank?
Capacitor banks act as a source of local reactive power and thus less reactive power flow through the line. By using a capacitor bank, the power factor can be maintained near to unity. Improving power factor is the process of reducing the phase difference between voltage and current.
