If you have ever looked at some ceramic capacitors and wondered how they can possibly get so bad, you are not alone. The problem with ceramic filters is that they can be prone to mechanical failure high voltage ceramic disc capacitors. This mechanical failure can result in serious problems for devices such as bench-top personal computer circuits and even industrial electric motors. Before someone decides to throw out a $100K ceramic capacitor just because they go bad, perhaps they should ask themselves why they would purchase one in the first place.
Do Ceramic Capacitors Go Bad?
A defective ceramic unit can be caused by numerous different sources, including temperature change, mechanical failure, chemical exposure, and manufacturing defects. All of these can be common causes, although it is possible that only one or two of them are actually at fault. If your ceramic device suddenly begins to act up and you determine that it is experiencing a mechanical failure, it is best to cut that particular component loose until you can get a technician out to see what is really going on. You never know until you try to replace a component!
When a ceramic capacitor fails, there are a few things that you can do to try to diagnose and fix the problem. First of all, you should remove any associated wires from the circuit and if possible the capacitor itself and see if it is showing any signs of wear. If the component is still receiving electricity despite the replacement, the chances are that the wire harness has become slightly damaged or may need to be replaced entirely.
Finally, if you find that a capacitor is causing your device to act up when it is supposed to be working, or if you find that it is having an abnormal amount of current flowing through when it should not, then you most likely have a faulty ceramic unit installed in your computer or other electronic device.
