Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors (Al-ele caps), are the most common type of electrolytic capacitors used in electronic equipment. They are widely used in a variety of electronic systems, from portable electronic devices, to highly sophisticated computer systems. The UPM1V680MED1TD aluminum electrolytic capacitor is one such capacitor that is used in a wide range of applications. This article aims to discuss its application field and working principle.

The UPM1V680MED1TD capacitor is designed for general-purpose applications and features an extended temperature range of -40C to +85C. It is an ideal choice for power supplies, voltage regulation applications and UPS systems. The UPM1V680MED1TD capacitor can handle high ripple current up to 6.0A, providing superior performance and reliability. It features a low equivalent series resistance (ESR), of 0.000058 Ohm, and a low self-discharge rate of 0.7% per year, ensuring long service life.

The UPM1V680MED1TD aluminum electrolytic capacitor works by forming an electrolyte film between a rod and a widely wound anode or “anodic layer”. The rod and anode are placed in an electrolyte solution, typically a potassium hydroxide-filled jar or cell. When an electrical circuit is connected to the capacitor, an electrical current is established between the rod and anode. This current causes electrolysis of the electrolyte and the formation of a thin film moisture layer on the inner surface of the electrolytic cell. This moisture layer serves as insulation between the rod and the anode, providing a varying capacitance value.

The capacitance value of UPM1V680MED1TD aluminum electrolytic capacitor is highly dependent on the temperature of the electrolyte used. As the temperature rises, the electrolyte “shrinks” in volume, which increases the space available for moisture to be adsorbed on the inner walls of the capacitor. As a result, the capacitance value increases. Conversely, as the temperature drops, the electrolyte “expands”, decreasing the space available for moisture, which reduces the capacitance value.

The capacitance of the UPM1V680MED1TD aluminum electrolytic capacitor is also affected by the presence of impurities in the electrolyte such as chlorides, sulfates, and inorganic metallic oxides. Impurities reduce the capacitance by decreasing the surface tension of the electrolyte, which reduces the area of the electrolyte film available for adsorption of moisture. The presence of impurities also increase the polarization of the electrolytic cell, causing a decrease in the current flow.

The UPM1V680MED1TD aluminum electrolytic capacitor can be used in a variety of applications. It is commonly used in power supplies, voltage regulators, UPS systems, and other low to medium frequency electronic circuits. It can also be used to provide decoupling for television converters and stabilizers, decoupling for motor controllers, and AC line filtering. Additionally, the UPM1V680MED1TD capacitor can be used in consumer electronics applications such as CD players, portable CD players, and personal audio systems. Moreover, the UPM1V680MED1TD capacitor can also be used for EMI/RFI suppression, flash memory storage and switching applications.

In conclusion, UPM1V680MED1TD aluminum electrolytic capacitor is a highly reliable and versatile component that can be used in a variety of applications, from consumer electronics to industrial control systems. It works by forming an electrolyte film between a rod and a widely wound anode or “anodic layer”, which provides varying capacitance values depending on the temperature of the electrolyte and the presence of impurities. The UPM1V680MED1TD capacitor is capable of handling high ripple currents of up to 6.0A and features a low equivalent series resistance (ESR) and a low self-discharge rate, ensuring long service life for electronic applications.
