An aluminum electrolytic capacitor, also known as an aluminium electrolytic capacitor, is an electrical component that employs an electrolyte in conjunction with an aluminum sheet as its anode, and is used as a device for storing electric charge. Its EKZN250ELL680ME11D is an aluminum electrolytic capacitor of the E series, with an operating temperature range of -40℃-85℃.

The EKZN250ELL680ME11D application field is mainly concerned with high-frequency switching power supplies, such as the output stage of large-scale power supplies, converters, and switching transformers. It is also a reliable choice for other applications that require high-capacitance and high-voltage. The EKZN250ELL680ME11D aluminum electrolytic capacitors can also be used in general purpose circuit and low-frequency filtering.

The working principle of an aluminum electrolytic capacitor revolves around the electric double layer effect, where an electric double layer is created between the anode (aluminum foil) and the electrolyte, which is separated by a highly porous dielectric layer made of paper, plastic, or rubber. This electric double layer stores electrical charge, which provides capacitance. The value of the capacitance depends on the size of the surface of the anode and the dielectric thickness, as well as on the nature of the electrolyte.

The main benefit of the aluminum electrolytic capacitor is its high capacitance potential. An aluminum electrolytic capacitor offers a large capacitance relative to the physical size of the component, meaning it can store more electric charge in a much smaller package. In fact, the EKZN250ELL680ME11D can offer a wide capacitance range, from 0.1uF to 680uF. That means it can easily store an entire DC voltage with a single capacitor.

The EKZN250ELL680ME11D is also designed to be highly reliable, with an operating temperature up to 105℃, and a lifetime of up to 2000 hours. It also offers excellent current performance and low ESR values, providing highly efficient power management.

In summary, the EKZN250ELL680ME11D aluminum electrolytic capacitor is suitable for applications requiring high capacitance and voltage, as well as for general purpose circuit and low-frequency filtering applications. Its working principle utilizes an electric double layer effect, allowing it to store an entire DC voltage with a single component, offering excellent performance and reliability.
