Aluminum Electrolytic Capacitors are widely used in power electronics and power supplies, primarily for voltage conversion and motor control. In addition, they are used for electromagnetic interference suppression, energy storage, and maintaining a constant voltage supply. The MVE25VE102ML17TR is a popular example of an aluminum electrolytic capacitor. This article will explore the application field and working principle of the MVE25VE102ML17TR.

The MVE25VE102ML17TR is a high-temperature, low-profile, surface-mount aluminum electrolytic capacitor. It is rated for an operating temperature range of -55°C to +105°C. It is also designed with a low ESR (equivalent-series resistance) of 0.08 Ohm at 120Hz, making it ideal for high-current applications such as power supplies, motor drives, and DC/DC converters. What’s more, its superior capacitance stability of +/-20% from -55°C to +105°C makes it suitable for space-constrained applications such as fixed wireless base stations, telecommunication systems, and high temperature automotive applications.

The MVE25VE102ML17TR aluminum electrolytic capacitor features an anode formed from aluminum foil and covered with an extremely thin layer of activated oxide. The aluminum foil is etched to provide a large surface area. The oxide layer forms an electron-conducting barrier, allowing for a high capacitance and energy storage capacity. The cathode is composed of an electrolyte/paper/polymer composite. This specific capacitor type also contains a self-healing element, which can restore a capacitance loss due to fatigue or short-circuiting.

The MVE25VE102ML17TR aluminum electrolytic capacitor is specifically designed to offer stability and reliability in high-temperature applications. Its superior temperature-dependence and low ESR enable it to maintain the performance of power supplies and motor drives even in the presence of high temperature variations. This particular capacitor type is ideal for industrial, automotive, aerospace, telecommunication, and other high-temperature applications. In addition, it is highly resistant to corrosion and offers excellent energy storage and discharge capacity.

The working principle of the MVE25VE102ML17TR aluminum electrolytic capacitor is based on chemical and electrical processes. It works by storing a charge between two electrodes, an anode and a cathode. Electrons move from the anode to the cathode when a voltage is applied across the two electrodes. In the case of an electrolytic capacitor, the anode is composed of aluminum foil and an oxide layer, while the cathode is composed of a paper/electrolyte/polymer composite. When voltage is applied, the electrons move through the oxide layer to the cathode. This forms an electrical charge, thus storing energy.

In conclusion, the MVE25VE102ML17TR aluminum electrolytic capacitor is designed to offer superior performance and reliability in high-temperature applications. Its low ESR and excellent capacitance stability make it an ideal choice for a wide range of power supplies, motor drives, and DC/DC converters. Its working principle is based on chemical processes between the aluminum anode and the paper/electrolyte/polymer cathode. This causes a strong electrical charge to form, thus allowing for efficient energy storage and discharge. The MVE25VE102ML17TR is sure to be a reliable and long-lasting solution for any high-temperature application.
