Electrolytic capacitor: Properties and operation
Electrolytic capacitors consist of two electrodes (anode and cathode), a film oxide layer acting as a dielectric and an electrolyte. The electrolyte brings the negative potential of the cathode closer to the dielectric via ionic transport in the electrolyte [7] (see Fig. 2).The electrolyte is either a liquid or a polymer containing a high concentration of …
Capacitor Failures
Open mode failure. An open mode failure in a capacitor can have undesirable effects on electronic equipment and components on the circuit.
