Capacitor Characteristics, Temperature Coefficient, Tolerance

A capacitor has large number of specifications and characteristics. By observing the information printed on the body of a capacitor, we can understand very well about the characteristics of a capacitor. But some capacitors have colors or numeric codes on their body, due to this it is difficult to understand about characteristics.

How to Read a Capacitor: 13 Steps (with Pictures)

If you are building an AC circuit, look for a capacitor rated specifically for VAC. Do not use a DC capacitor unless you have an in-depth knowledge of how to …

Capacitance in AC Circuits and Capacitive Reactance

The capacitance value of 50uF is exactly the same and the 450VAC rated capacitor has a better tolerance. 330VAC implies its a "Starting" capacitor, 450VAC implies its a "Run" capacitor. As the nominal voltage of 450V is higher than 330V, you can use a 450V rated capacitor inplace of a 330V rated one, although the physical size may be different.
