Aluminum electrolytic capacitors are composed of two aluminum foils and an insulating film, and their capacitance mainly depends on the area of the electrode foil and the thickness of the dielectric film, which is the highest in all dielectric capacitors. It is widely used in various applications, such as filtering and buffering, energy storage, and stability, and one of the most often used types of aluminum electrolytic capacitors is UCP2W680MHD.

UCP2W680MHD is an aluminum electrolytic capacitor with a rated voltage of 400V in a standard SMD package. It has a built-in ESR of 0.02Ω, which is suitable for use with high-frequency circuits and can provide improved performance in vibration and shock environments. In addition, it has a capacitance of 680uF, which makes it unbeatable in providing high-capacity low-resistance energy storage.

The UCP2W680MHD is typically used in power supplies, audio/video equipment, power amplifiers, and portable equipment, among others. With its low ESR and large capacitance, it serves to filter and regulate the output of an AC power line, or provide power storage for DC-DC converters and power supplies.

The working principle of the UCP2W680MHD capacitor is based on the basic principle of two parallel aluminum plates separated by electrically insulating material. When a voltage is applied across the electrolyte, a negative charge is built up on one plate and a positive charge on the other. This creates an electric field between the two plates, which attracts electrons from the negative plate through the dielectric glass layer and to the positive plate. The effect of this setup is to create an electrical field between the two plates that is proportional to the voltage applied. By increasing or decreasing the voltage, the electric field between the plates can be varied, thus changing the capacitance of the capacitor.

The UCP2W680MHD has a wide application range and is one of the most commonly used aluminum electrolytic capacitors. It is typically used in power supplies, audio/video equipment, power amplifiers, and portable equipment. It has a low ESR and high capacitance, making it especially suitable for filtering and regulating the output of an AC power line as well as providing power storage for DC-DC converters and power supplies. Its working principle is based on two parallel aluminum plates separated by electrically insulating material, and its capacitance is proportional to the voltage applied between these two plates.
