Aluminum-Polymer Capacitors & RR50E821MDN1KX

Aluminum-polymer capacitors are a type of electrolytic capacitor with an anode composed of a solid aluminum foil and a cathode composed of a polymer film. Due to their unique construction, aluminum-polymer capacitors offer a variety of benefits compared to the traditional electrolytic capacitor.

The RR50E821MDN1KX is a combination of aluminum-polymer capacitors with a rated voltage of 50v and a capacity of 821 µF. It is primarily used in DC/DC converters, DC/AC inverters, and power regulators. Due to its high capacity and low ESR, it is a popular choice for those applications.

Working Principle

An aluminum-polymer capacitor is built upon two electrolytic sheets separated by a polymer film. The anode is composed of a solid aluminum foil and the cathode is composed of a polymer film. The polymer film serves as the dielectric between the anode and the cathode. When the capacitor is charged, electrical charges build up on both the anode and the cathode, thus forming an electric field. This field increases the dielectric strength of the capacitor, allowing for a high voltage rating and a low equivalent series resistance (ESR).

The RR50E821MDN1KX is a combination of aluminum-polymer capacitors with a rated voltage of 50v and a capacity of 821 µF. The capacitance of the capacitors is determined by the thickness of the polymer film. Additionally, the capacitance increases with an increase in the surface area of the capacitor. This makes RR50E821MDN1KX capacitors an ideal choice for applications needing large capacitance values at higher voltages.

Benefits of Aluminum-Polymer Capacitors

Aluminum-polymer capacitors offer a unique combination of benefits compared to traditional electrolytic capacitors. The main advantage is their extended temperature range which allows them to withstand temperatures up to 125°C. This makes them ideal for applications in harsh environments and for use in high-power devices. Additionally, aluminum-polymer capacitors can operate at much higher frequencies than electrochemical capacitors. They also boast a higher dielectric strength which allows for larger voltage values.

Aluminum-polymer capacitors also provide superior electrical and mechanical stability when compared to traditional electrolytic capacitors. The construction of these capacitors is also very durable and resistant to shock and vibration. This makes them ideal for use in automotive and industrial applications where frequent mechanical shock is a factor.

Conclusion

Aluminum-polymer capacitors such as the RR50E821MDN1KX offer many advantages over traditional electrolytic capacitors. Their higher temperature range, higher dielectric strength and superior electrical and mechanical stability make them ideal for use in harsh environment or in high power applications. Additionally, they are very durable and resistant to shock and vibration, making them well suited for automotive and industrial applications.
