Aluminum – Polymer Capacitors

The RL81C271MDNASQPX is a type of aluminum-polymer capacitor. It is a non-electrolytic type of capacitor made from a single layer of aluminum foil and a polarizable dielectric polymer. This capacitor is a form of surface mount capacitor that provides reliable performance in high temperature, high humidity, and vibration or shock environments.

Application Fields

Aluminum-polymer capacitors, including the RL81C271MDNASQPX, are used in a variety of applications. These capacitors are primarily used in applications which require a high capacitance and a low equivalent series resistance (ESR). Examples include motor drive circuits, switching power supplies, and in photovoltaic energy storage systems.

Aluminum-polymer capacitors are also used in energy storage and filtering applications, as well as in RFID, telecom, and automotive applications. These capacitors can also be used in audio and other electronic applications requiring high capacitance and low ESR.

Working Principle

Aluminum-polymer capacitors, such as the RL81C271MDNASQPX, work on the principle of charge separation. When an external voltage is applied to the capacitor, a positive charge accumulates on one electrode and a negative charge accumulates on the other. This charge separation creates an electric field which stores energy in the capacitor, allowing it to store a charge electrostatically.

The dielectric material used in the RL81C271MDNASQPX is a polarizable polymer. This polymer allows for greater capacitance at higher frequencies, thanks to its ability to become polarized in the presence of an applied electric field. This higher capacitance, in turn, allows these capacitors to be used in applications which require a large amount of energy storage.

In addition to higher capacitance, aluminum-polymer capacitors also exhibit lower ESR compared to other types of capacitors. This reduced ESR allows these capacitors to provide improved accuracy and stability in sensitive electronic circuits.

Conclusion

The RL81C271MDNASQPX is a type of aluminum-polymer capacitor. It has a high capacitance and low ESR, which make it a great choice for applications that require a large amount of energy storage and stability. These capacitors are used in a variety of applications, including motor drive circuits, switching power supplies, photovoltaic energy storage systems, and audio equipment.
