Aluminum-Polymer Capacitors

A 4SW180M2.9X7.3 capacitor is one type of aluminum-polymer capacitor designed to store electrical energy. The term aluminum-polymer defines the construction of the capacitor, which is composed of two metallic electrodes and a polymer electrolyte. This type of capacitor offers many advantages over traditional ceramic, electrolytic, and tantalum capacitors.

The key benefit of the 4SW180M2.9X7.3 aluminum-polymer capacitor is its energy storage capacity. It is capable of storing four times more energy than a ceramic capacitor, and two to three times more energy than an electrolytic or tantalum capacitor. This makes the 4SW180M2.9X7.3 a particularly well-suited option when a high amount of energy storage is required. Another benefit of the 4SW180M2.9X7.3 aluminum-polymer construction is its high level of efficiency, which is greater than ninety-five percent. Additionally, the capacitor has a much lower equivalent series resistance (ESR) value than other types of capacitor technology.

The aluminum-polymer construction that makes up the 4SW180M2.9X7.3 allows for very low capacitance dielectric loss. The polymer electrolyte material also increases the frequency range up to the audio frequency region, which is ideal for frequencies associated with audio or telephone applications. The 4SW180M2.9X7.3 aluminum-polymer capacitor also has an impressive self-healing capability. This self-healing characteristic provides an extra level of protection and can greatly extend the life of the capacitor.

The major application fields for the 4SW180M2.9X7.3 aluminum-polymer capacitor include resonant circuits and audio applications requiring large concentration. This capacitor is also used in applications involving digital filters, where the low ESR of the device is especially beneficial. Another common application field is in power supplies, where the capacitor is employed as a storage device. In these cases, its ability to store large amounts of energy and its good power dissipation characteristics prove to be very advantageous.

The 4SW180M2.9X7.3 aluminum-polymer capacitor operates on a principle called electrochemical redox reaction. Through this process, ions move between two electrolytes, creating the electrical energy storage effect. This is achieved by the employment of a polymer material, which surrounds both electrodes and acts as the electrolyte.

In this way, the 4SW180M2.9X7.3 aluminum-polymer capacitors offer many advantages over other capacitor technologies. The improved energy storage, frequency range, efficiency, and ERS are especially beneficial for applications involving audio frequency signals, power supplies, and digital filters. By combining the features of both aluminum and polymer materials, the 4SW180M2.9X7.3 capacitor offers the perfect solution for such applications.
