Reasons Why Capacitors Fail. As you can see, the capacitors do a fairly tough job. They also go through a lot of wear and tear, as their work will easily take a toll on them physically. Due to this reason, it''s not unusual for AC capacitors to fail before any other part does.
A 50V part, for example, can be subjected to 50V continuous voltage and be expected to work just fine. Some capacitors, especially film capacitors, have different ratings for AC voltage (VAC) and DC voltage (VDC). Ensure you''re looking at the correct voltage for your application! Higher voltage is better.
