Aluminum-Polymer Capacitors are considered some of the most versatile electrical components available today. This new generation of capacitors offers a variety of advantages over traditional aluminum electrolytic capacitors, including higher capacitance per unit volume and longer life span. In this article, we will explore the application field and the working principle of the 157AVG035MFBJ capacitor.

The 157AVG035MFBJ capacitor is an aluminum-polymer capacitor that is both very compact and efficient. It has a capacitance of 3.5mF and is rated for operation up to 50V Operating Voltage. As it is a long life capacitor, its service life is estimated to be over 200,000 hours at 65°C. The 157AVG035MFBJ capacitor is ideal for many applications in various industrial and consumer electronics, such as PC motherboards, power supplies, UPSes (Uninterruptible Power Supplies), audio circuits, solar energy systems, data networks, and any other application that requires low ESR and long life.

Aluminum-polymer capacitors, including the 157AVG035MFBJ, are constructed with an anode foil made of aluminum combined with polymer material, and a cathode that is usually made of a tantalum-like material. This construction creates a very stable capacitor with very low ESR (equivalent series resistance). The polymer layer also helps to reduce loss, as it increases the voltage ratings of the capacitors. This combination of aluminum and polymer makes aluminum-polymer capacitors the ideal choice for high frequency and low ripple applications.

The working principle of the 157AVG035MFBJ is fairly simple. The aluminum foil acts as a plate, while the polymer layer acts as an insulator for the plates. When a voltage is applied to the capacitor, electrons will be attracted to the negative electrode and released from the positive electrode resulting in the capacitance value. This is known as dielectric absorption, and it is an essential process for the efficient operation of the capacitor.

In conclusion, the 157AVG035MFBJ capacitor is a valuable electrical component for many industrial and consumer electronics applications. It offers a long service life and higher capacitance per unit volume than traditional aluminum electrolytic capacitors, making it ideal for applications that require low ESR and long life. The working principle of the capacitor is relatively simple: the aluminum and polymer layers create an efficient capacitor with low ESR, while dielectric absorption helps to control the capacitance value. Aluminum-polymer capacitors are a great choice for any high frequency and low ripple application.
