Aluminum electrolytic capacitors are composed of an anode aluminum foil, a cathode aluminum foil and an electrolyte. The two aluminum foils are separated by a thin dielectric oxide film which acts as an insulating barrier. In addition, the anode and cathode foils are separated by a paper gasket, ensuring that the two foils are properly insulated.The typical working principle of aluminum electrolytic capacitors is outlined below. When a potential difference is applied across the capacitor, electrons are attracted to the negative terminal and repelled from the positive terminal. This creates an electric field within the capacitor, causing the electrolyte to rapidly absorb ions of the opposite charge. The charge is attracted to the inner surfaces of both the anode and cathode foils, thereby storing electrical energy. The EKMM421VNN121MA20T is a type of aluminum electrolytic capacitor manufactured by the Panasonic Corporation. This capacitor has an operating temperature range of -40°C to +125°C and is typically used in industrial applications where stability and reliability are essential. The EKMM421VNN121MA20T is designed to provide long-term reliability in the most demanding applications. It features an insulated aluminum case that prevents damage from static electricity, dust, and other corrosive agents. In addition, the capacitor is hermetically sealed, ensuring a full range of temperatures from -40°C to +125°C without any changes in operating performance. The capacitor also has a wide operating voltage range (from 16V to 300V) and a high working voltage (100V). The EKMM421VNN121MA20T is designed to offer long-term reliability and stability in both low- and high-temperature environments. The capacitor can handle extremely high capacitance and ripple current values without compromising its performance. It also offers low-ESR (Equivalent Series Resistance) and high-temperature stability, which makes it suitable for industrial applications such as vehicle traction motors, temperature control/release systems, and frequency converters. Overall, the EKMM421VNN121MA20T aluminum electrolytic capacitor is a reliable and stable power source for industrial applications that require a wide operating temperature range and long-term reliability. It has a wide operating voltage range, a high maximum voltage, and an insulated aluminum case, which makes it suitable for even the most demanding applications.
