Aluminum - Polymer Capacitors

Aluminum - polymer capacitors or ‘Al-poly’ capacitors are a type of polymer electrolytic capacitor developed by Nippon Chemi-Con, a major Japanese electronics parts manufacturer. These capacitors have gained a loyal following due to their superior performance and long life, making them a cost-effective choice for high power applications. The RF80J331MDN1PX is one such capacitor, containing both aluminum and polymer elements to create a device with significant stability and robustness.

Applications

The RF80J331MDN1PX is best suited for use in filters, signal processing, and electric power converters. It is an ideal choice for a wide range of applications such as high-performance audio and video equipment, automotive electronics, communications systems, and more. It is also suitable for use in batteryless electronic devices as its high RF immunity resists external noise affecting the circuit.

Features and benefits

The RF80J331MDN1PX has a number of beneficial features and characteristics. It offers a low ESR value of 0.25 Ω which results in superior ripple current handling capabilities. This device also has a high capacitance rating of 3300μF at 2.5VDC, allowing for maximum storage of energy. Its small form factor helps to reduce the overall size of circuits containing it, making it ideal for use in compact applications. In addition, it is rated for an operating temperature range of -25°C ~ +85°C, making it suitable for outdoor as well as indoor applications.

Working principle

The RF80J331MDN1PX utilizes a combination of aluminum and polymer electrolyte to create a hybrid capacitor. The aluminum component acts as the negative electrode and the polymer acts as the positive electrode. When a voltage is applied to the device, an electrical current flows between the anode and the cathode, creating an electric field that stores energy for later discharge. This charging and discharging cycle is the basis of its working principle.

The RF80J331MDN1PX aluminum-polymer capacitor offers a number of beneficial features such as excellent ripple current handling, high capacitance rating, small form factor, and wide operating temperature range. This makes it suitable for a wide range of applications in audio, video, automotive, communications, and other electronic devices. Its hybrid construction allows it to store energy efficiently and withstand high temperatures, making it an ideal choice for high-end applications.
