Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrochemical capacitors, are polarized capacitors whose anode electrode is an aluminum foil with an etched surface covered with an oxidized layer that acts as the dielectric, and the cathode is a liquid or solid electrolyte. As a type of capacitor, aluminum electrolytic capacitors are widely used in a range of applications.The specific model of aluminum electrolytic capacitor, 420QXW47MEFC10X40, is a general-purpose capacitor used for decoupling signals or gaming applications, among other applications. This capacitor offers convenient, cost-effective performance in various electronics projects.The 420QXW47MEFC10X40 aluminum electrolytic capacitor is designed to provide low-impedance signal line bypass or low-impedance gaming applications. It can also provide excellent damping for noise and interference from digital switching power supplies, as well as an effective way to filter out switching frequency noise.The capacitance and voltage stand-off of the 420QXW47MEFC10X40 aluminum electrolytic capacitor are 47μF and 100V respectively. This capacitor features an operating temperature range of -40°C to +85°C and a maximum dissipation factor of 7.0%. It also comes with high ripple current rating of 3.3A, which is suitable for various decoupling applications.In terms of working principle, the 420QXW47MEFC10X40 aluminum electrolytic capacitor stores electrical energy by setting up an electric field between two separated conductors. This electric field acts as a dielectric between them, and energy is stored as electrical charge. This capacitors features an anode consisting of a metal foil and a cathode consisting of a liquid or solid electrolyte, and energy is transferred between them by means of electrolysis, or movement of electrons from one conductor to another.The 420QXW47MEFC10X40 aluminum electrolytic capacitor also features increased internal resistance. This effectively eliminates the possibility of high-frequency noises, thus improving the stability and safety of the system. The temperature of the capacitor needs to be monitored closely, as the higher temperature may cause the oxidized layer on its anode to deteriorate, which would drastically decrease its capacitor lifetime.In conclusion, the 420QXW47MEFC10X40 aluminum electrolytic capacitor is widely used in various applications including decoupling signals, gaming applications, and can also provide excellent damping for noise. This capacitor is designed to provide low-impedance signal line bypass or low-impedance gaming applications, with a capacitance and voltage stand-off of 47μF and 100V respectively. Additionally, it features increased internal resistance, which eliminates the possibility of high-frequency noises, thus improving stability and safety of the system.
