What is an Aluminum - Polymer Capacitor?

An aluminum - polymer capacitor, also known as an aluminum electrolytic capacitor, is a type of capacitor which is composed of two thin layers of aluminum foil separated by polymer film. The principle of an aluminum - polymer capacitor is the same as a standard electrolytic capacitor; the two thin layers of aluminum foil act as the capacitor plates and the polymer film acts as the dielectric layer. The combination of the thin layer of aluminum foil, the polymer film and their electrodes gives an aluminum - polymer capacitor a low profile and small size which makes it well suited for applications where space is limited. The aluminum - polymer capacitor can also be used in applications where higher-frequency signals are present.

RNU1J560MDN1PH Application Field and Working Principle

The RNU1J560MDN1PH is an aluminum - polymer capacitor with a width of 8.1 mm, a height of 1.6mm and a rated voltage of 10V. This type of capacitor is typically used in applications requiring low ESR (Equivalent Series Resistance), such as in power supplies and electronic circuits.The working principle of the RNU1J560MDN1PH is based on the same basic principles as other aluminum - polymer capacitors. The two thin layers of aluminum foil act as the capacitor plates and the polymer film acts as the dielectric layer. When a voltage is applied to the capacitor, the electric field created causes a displacement of charge between the two plates. This displacement results in a capacitance or the ability to store energy. The ESR is determined by the dielectric layer thickness, the size of the capacitor and the quality of the aluminum foil.

Benefits of Using an Aluminum - Polymer Capacitor

Aluminum - polymer capacitors offer a wide range of benefits to users compared to traditional electrolytic capacitors. Firstly, the low profile nature of aluminum - polymer capacitors allows for significantly reduced board space requirements. This makes these capacitors well suited for high density applications. Secondly, these capacitors have excellent charge-discharge characteristics and are able to withstand high temperature and humidity levels, making them a very reliable component. Finally, they are ideal for high frequency applications due to their low ESR and ESL (Equivalent Series Inductance) characteristics.

Limitations of Using an Aluminum - Polymer Capacitor

The main limitation of using an aluminum - polymer capacitor is its limited capacitance range. Generally speaking, aluminum - polymer capacitors are available with a maximum capacitance of around 2,000µF (2mF). This may be a limiting factor for some applications. Additionally, these types of capacitors are more expensive compared to standard electrolytic capacitors.

Conclusion

The RNU1J560MDN1PH aluminum - polymer capacitor is an ideal choice for applications requiring low ESR, high reliability and a small form factor. Its reduced board space requirements and its excellent charge-discharge characteristics make it suitable for high density applications, while its low ESR/ESL characteristics make it ideal for high frequency signals. While its limited capacitance range and more expensive cost may be drawbacks, they may be outweighed by its other benefits.
