Aluminum - Polymer Capacitors

RR50J471MDN1KX capacitors are a type of aluminum-polymer capacitors. Like other aluminum-polymer capacitors, they have a very low equivalent series resistance (ESR) that is suitable for applications requiring low power losses. Additionally, they have a very long operating life in the range of 10,000 to 20,000 hours. This makes them an attractive choice for applications with life cycles that span multiple years.

Application Field

RR50J471MDN1KX capacitors are used in a variety of applications such as AC/DC power converters, renewable energy systems, industrial motor control systems, and personal computers. They can also be used for instrumentation, power supplies, automotive electronics, and numerous other electronics. Their low ESR and long life make them especially suited for applications that require a high degree of reliability and performance.

Working Principle

RR50J471MDN1KX capacitors use an anode made of aluminum and an electrolyte of a polymer such as ethylene vinyl acetate (EVA). When current is applied to the capacitor, it builds up an electric field, causing electrons to move between the anode and the electrolyte. This movement of electrons is what stores charge in the capacitor.

The electrolyte between the plates facilitates the transfer of electrons and also prevents the plates from short-circuiting each other. By controlling the amount of electrolyte between the plates, the capacitance and ESR of the capacitor can be varied. The polymer layer also provides noise suppression and stability.

RR50J471MDN1KX capacitors are ideal for applications requiring low ESR, low power losses, and a long operating life. Their ability to be easily tailored to the requirements of a specific application makes them a great choice for various electronics projects.
