Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are commonly used components in electronics. They are passive electrical components which store electrons and help to provide electrical power to devices. They are widely used in a variety of applications, from power supply devices to radio transceivers.The specific product of aluminum electrolytic capacitors under discussion is the part number 400RX301MT78X11.5. This part was manufactured by Nippon Chemicon and is a small, high-performance aluminum electrolytic capacitor with a diameter of 11.5mm in a radial design ideal for applications with limited space. The capacitor is composed of two aluminum foil electrodes which are separated by an oxide film. The positive electrode is coated with a solid electrolyte, usually electrolytic paper soaked in a paste of conductive aluminum oxide. The negatively charged electrodes are enclosed in a metal case filled with an electrolyte solution. When they are exposed to an electric current, the positively charged electrolyte adheres to the electrodes and forms a dielectric which can then store electrical charge. The 400RX301MT78x11.5 capacitor is suitable for applications requiring high levels of voltage and energy storage, such as high-frequency power supplies, motor drives and DC/DC converters. It offers high capacitance, low equivalent series resistance (ESR), low equivalent parallel resistance (ESP), and excellent surge current capabilities. It is also highly resistant to vibration and impact, helping to ensure long service life. In addition, the capacitor features a voltage rating of 400V, a capacitance of 301μF, and a temperature range of -40°C to +85°C. This makes it well suited for a variety of power supply applications in a broad range of temperatures, from industrial to automotive.To sum up, the 400RX301MT78X11.5 is a high-performance small-sized aluminum electrolytic capacitor with excellent power and temperature characteristics, making it ideal for applications requiring high levels of voltage and energy storage. Its durable design, with high capability of surge current, low ESR, and low ESP makes it suitable for use in high-frequency power supplies, motor drives, and DC/DC converters, as well as a range of other applications.
