Aluminum Electrolytic Capacitors

UPJ1E470MED Application Field and Working Principle

Aluminum electrolytic capacitors are indispensable components in many electronic circuits and have wide application in various fields from consumer electronics to automotive industry. UPJ1E470MED series aluminum electrolytic capacitors are specially designed to provide reliable performance and long service life in various low-cost consumer and communication products. In details, UPJ1E470MED series aluminum electrolytic capacitors are characterized by the long life of up to 2000 hours at rated ripple current, high ripple current of 673mA, volumetric efficiency and low ESR offering up to 27mΩ. With its colorful housing, the capacitor is available in three different sizes, 105°C rated temperature and a voltage rating of 35V. Moreover, the UPJ1E470MED series aluminum electrolytic capacitors use conductive polymers as cathode negative solution to prevent leakage, possessing excellent reliability and stability. These capacitors are widely applied in areas such as DC decoupling, bypass, blocking, smoothing and filtering. How to understand the working principle of an electrolytic capacitor is crucial to understand its application. An electrolytic capacitor is a polarized device to store energy in form of electric charges or electric field. It consists of two conducting plates separated by a layer of electrolyte. The negative plate is conventionally made of aluminum oxide and the electrolyte, a liquid or gel, can be either inorganic or organic. The basic working principle for electrolytic capacitor is that the aluminum foil of the negative plate gets oxidized creating insulating layer on its surface. This means that if a voltage is applied between the positive and negative plate, the positive plate accumulates positive charge and the net negative charge accumulates in the aluminum oxide layer isolating the two plates of the capacitor. When the voltage is removed, charges on the positive plate are transferred to the negative plate where they are stored while the conductive aluminum oxide additionally behaves as a dielectric device. To sum up, UPJ1E470MED series aluminum electrolytic capacitors offers excellent features and performance, making it a great option for all of the applications in consumer and communication products. Its working principle, which involves the principle of insulating aluminum oxide layer and charge storage, enables a great efficiency and extends the lifetime of the capacitor up to 2000 hours in a wide range of applications. The UPJ1E470MED series aluminum electrolytic capacitors are a popular choice for a variety of applications, providing great life time and reliable performance under various conditions. With its long life and low ESR, it is an ideal solution for cost-effective consumer electronics and communication products.
