Difference Ceramic Electrolytic Capacitor

Ceramic and electrolytic capacitors are two types of capacitors used in electronic circuits.

Difference ceramic electrolytic capacitor.

In addition the uses of the two are also different. 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. The ceramic capacitors are the capacitors and use the ceramic material as a dielectric. These capacitors are unpolarized.

In ceramic capacitors the dielectric is a thin layer of ceramic and both plates are metal foil. Ceramic capacitors are generally used for signal source filtering while electrolytic capacitors are generally used for power supply. In these two applications a large ac voltage signal is applied across the capacitor. 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.

These capacitors have negligible internal inductance or resistance. Made of ceramic material as the dielectric and metal as the electrodes ceramic capacitors come in a variety of shapes and sizes. 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. Electrolytic capacitors have polarity i e.

Ceramic capacitors don t have polarity their terminals can be interchanged they are suitable for both ac and dc. The examples are the speaker crossover filters and power factor correction network. They have fixed positive and negative terminal suitable for dc only. They don t have any chemical reaction involved in their working they have lesser capacity for the same given size.

The difference between electrolytic capacitor and ceramic capacitor the ceramic capacitor is a capacitor made of a ceramic material as a medium a layer of metal film coated on the surface of the ceramic and then sintered at a high temperature as an electrode.
