EKZN350ELL821MK20S

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components containing two electrodes: an anode and a cathode, separated by an electrolytic medium. When connected to a power source, the electrolytic material will gain or lose electrons in a process called oxidation-reduction. As a result, an electrical charge is created on the anode, and a smaller flow of electrons is created on the cathode. This electrical charge is referred to as the stored energy.

EKZN350ELL821MK20S Application Field and Working Principle

The EKZN350ELL821MK20S is a type of aluminum electrolytic capacitor, most commonly used in high temperature applications. It is designed for use in either air or oil filled environments. This particular capacitor features excellent high temperature characteristics and can withstand temperatures up to 125°C. Its high capacitance and low ESL make it an ideal choice for power factor correction, noise suppression, and decoupling applications.

The EKZN350ELL821MK20S capacitor works by storing energy within the electrolytic medium, between the two electrodes. When a power source is connected to it, electrons flow into the capacitor from the anode terminal, and then out of the capacitor into the cathode terminal. This creates an electrical field between the two electrodes, and the charge stored in the electrolytic medium is known as the “capacitance”.

The EKZN350ELL821MK20S capacitor also has a low equivalent series inductance (ESL), which helps reduce acoustic noise and output voltage drop. It also has a low dissipation factor (DF), which increases efficiency and improves heat dissipation. This helps achieve longer lifespan and higher current ratings than other types of capacitors.

Due to its high temperature rating and excellent performance characteristics, the EKZN350ELL821MK20S is suitable for a variety of applications. It can be used in power factor correction, noise suppression, and decoupling. It is also widely used in high frequency switching circuits, ignition systems, switching power supplies, and automotive electronics.

In conclusion, the EKZN350ELL821MK20S is a high-performance aluminum electrolytic capacitor, typically used in high temperature applications. It features excellent high temperature characteristics, low equivalent series inductance, and low dissipation factor. It is suitable for use in power factor correction, noise suppression, and decoupling, as well as a variety of other applications.
