WebbAs a general rule of thumb, before sticking your hands in a circuit with potentially charged capacitors, especially power electronics like audio amplifiers and televisions. It is a good idea to short capacitors across a (largish) bleedoff resistor to discharge them. WebbUse a capacitor with the same capacitance, and the same or higher voltage rating. Also, Q is charge, and although it is the product of voltage and capacitance, you must use the applied voltage, not the rated.

WebbIf replacing one of the old tubular or cubic style ceramics, you might have to experiment with different replacements until you find one that has the right temperature characteristic. Ceramic disc capacitors often have three-letter codes on them such as 'Z5U' or 'NP0.'. Again, there are tables of these codes available online.
