elektrolüütkondensaatoris

Elektrolüütkondensaator is the Estonian term for an electrolytic capacitor. This is a type of capacitor that uses an electrolyte to achieve a larger capacitance value than is possible with other types of construction. Electrolytic capacitors are polarized, meaning they must be connected in a circuit with the correct polarity. Reversing the polarity can damage the capacitor. The anode of an electrolytic capacitor is a metal foil, typically aluminum or tantalum, which is oxidized to form a thin dielectric layer. The cathode is a conductive electrolyte, either wet or solid. Due to their high capacitance density, electrolytic capacitors are commonly used in power supply filtering, decoupling, and energy storage applications. They are also used in audio circuits for coupling and decoupling. However, they generally have a lower tolerance, higher leakage current, and a more limited lifespan compared to non-electrolytic capacitor types. The capacitance of an electrolytic capacitor is typically much larger than a similarly sized film or ceramic capacitor. Common values range from a few microfarads to several thousand microfarads, and voltage ratings can vary from a few volts to several hundred volts.
