Difference Ceramic Electrolytic Capacitor

Ceramic capacitors don t have polarity their terminals can be interchanged they are suitable for both ac and dc.
Difference ceramic electrolytic capacitor. Ceramic capacitors and electrolytic capacitors are two main types of capacitors that are widely used in electrical and electronic components. The ceramic capacitors are the capacitors and use the ceramic material as a dielectric. They don t have any chemical reaction involved in their working they have lesser capacity for the same given size. In addition the uses of the two are also different.
Made of ceramic material as the dielectric and metal as the electrodes ceramic capacitors come in a variety of shapes and sizes. In ceramic capacitors the dielectric is a thin layer of ceramic and both plates are metal foil. They have fixed positive and negative terminal suitable for dc only. In these two applications a large ac voltage signal is applied across the capacitor.
Electrolytic capacitors have polarity i e. The capacity of ceramic capacitors is generally small and the capacitance of electrolytic capacitors can be made very large. They are generally less expensive than other capacitors and carry lower capacitances couple of µf max which makes them used often during low capacitance requirements in noise harmonics filtering and suppression applications. These capacitors are unpolarized.
These capacitors have negligible internal inductance or resistance. Ceramic and electrolytic capacitors are two types of capacitors used in electronic circuits. The main difference between ceramic and electrolytic capacitor is that in ceramic capacitors the two conductive plates are separated by a ceramic material whereas in electrolytic capacitors the two conductive plates are separated by an electrolyte and a metal oxide layer. The ceramic capacitor uses a thin ceramic layer as the dielectric medium whereas the electrolytic capacitor uses an ionic liquid as one of the sheets of the capacitor.
Ceramic capacitors are generally used for signal source filtering while electrolytic capacitors are generally used for power supply.
