They have a high leakage current, comparable series resistance, and a short service life. Wet electrolytes or unidirectional polymer capacitors can be used in electrolytic capacitors. They are often constructed of aluminum or tantalum, however, other materials may be utilized. Polarisation is present in most electrolytic capacitors, which means that the voltage at the positive electrode must be larger than the voltage at the negative electrode.
- Used to reduce voltage fluctuations in various filtering devices.
- Used in output and input smoothing to filter when the DC signal is weak with the AC component.
- They are extensively used for noise filtering or decoupling in power supplies.
- They are used for coupling signals between amplifier stages and also to store energy in flashlamps.
