Aluminum electrolytic capacitors are widely used in commercial, industrial power supplies and different consumer electronics applications for their advantages of low cost, large capacitance, long life, high dielectric strength and excellent temperature stability. EKXJ421ELL470MM20S is a type of aluminum electrolytic capacitor. It is a long-life type that is suitable for high-temperature, high-humidity application with 2000 hours of guaranteed testing life.

The capacitance of EKXJ421ELL470MM20S is 47μF, with a rated voltage of 25V. It’s designed into a volume of only 0.175 inches, and is a surface mount component built with lead-free electrolyte. With a temperature range of -55℃ to +105℃, its performance is discrete and reliable.

The basic working principle of electrolytic capacitors is electrochemical double layer. The anode of the capacitor is oxidized aluminum foil anode. The anode layer forms a high-purity barrier oxide film, which is covered with a moderate proportion of electrolyte and activated carbon. Then, the cathode is a wetting of electrolyte and activated carbon, which is in balance with the anode. When a voltage is applied between the two electrodes, the anode oxide decreases, and a large capacitance is generated with its electric field effect.

The applications of EKXJ421ELL470MM20S aluminum electrolytic capacitors are performed not only in consumer electronics, but also for filtering, smoothing, decoupling circuit, and power supply in automotive and home appliance. And in order to enhance reliability such as computer motherboards and power supplies, because of its advantages of low cost, filter ripple, suppress noise and improve power supply more easily.

As mentioned earlier, aluminum electrolytic capacitors have a long life and are suitable for high temperature and humidity environment. This makes EKXJ421ELL470MM20S a reliable choice for applications which need long lifetime, high temperature stability, and high-current filtering.

To sum up, EKXJ421ELL470MM20S is a type of aluminium electrolytic capacitor with a low cost and a capacity of 47μF and a rated voltage of 25V. It is designed with a high degree of reliability as it has an excellent temperature and humidity stability, ideal for a variety of applications such as filtering, smoothing, decoupling circuit or power supply in automotive and home appliance.
