What are electrolytic capacitors?
Electrolytic capacitors are a type of capacitor used in electronic circuits to store and release electrical charge. They consist of two conductive plates separated by a dielectric and an electrolyte that serves as a conductive liquid. These capacitors are known for their high capacity in relation to their size.
There are two main types of electrolytic capacitors: Aluminum electrolytic capacitors and tantalum electrolytic capacitors. Aluminum electrolytic capacitors are widely used and have a high capacitance per volume, while tantalum electrolytic capacitors have an even higher capacitance per volume, but are also more expensive.
Electrolytic capacitors are commonly used in electronic devices such as computers, televisions, audio amplifiers, power supplies and many other applications where a stable and reliable power supply is required.

What are electrolytic capacitors used for?
Electrolytic capacitors are used in electronic circuits to store and release electrical charge. They are particularly useful when high capacitance is required as they offer a relatively high capacitance per size compared to other capacitor types.
Typically, electrolytic capacitors are used in switching power supplies, rectifier circuits, amplifier circuits, audio processing systems, motor controllers and many other electronic applications where a stable DC voltage is required or when AC power needs to be converted to DC.

What types of electrolytic capacitors are there?
There are several types of electrolytic capacitors, which can be differentiated according to their structure and the materials used:
Aluminum electrolytic capacitors: Aluminum electrolytic capacitors are the most common electrolytic capacitors. They consist of an aluminum foil as the anode, which is coated with a thin layer of an oxide that serves as the dielectric. The electrolyte liquid in which the cathode is soaked significantly improves the capacitance of the capacitor.
Tantalum electrolytic capacitors: Tantalum electrolytic capacitors are known for their high capacitance density and good performance at low temperatures. They use tantalum as the anode material and an oxide layer as the dielectric, which is produced by anodization.
Polymer electrolytic capacitors: Polymer electrolytic capacitors are a further development of aluminum electrolytic capacitors. They use organic polymer materials as the electrolyte, which leads to improved performance and a longer service life.
Hybrid electrolytic capacitors: Hybrid electrolytic capacitors combine the advantages of electrolytic capacitors with those of other capacitor technologies such as ceramic or tantalum. They offer a high capacitance density and good performance at low temperatures.
