Aluminum Electrolytic Capacitors and ECE-S1CG472E

An aluminum electrolytic capacitor is a type of capacitor with an anode composed of a rigid sheet of aluminum on which very thin layers of an oxide are created by anodizing and a cathode by a liquid or solid electrolyte. This is different from other types of capacitors that use two layers of metal material to form a capacitor, such as the film capacitor or the ceramic capacitor. Aluminum electrolytic capacitors are much smaller and lighter than most other types of capacitors, and can be designed to have a very high capacitance, from 1 µF to as high as 5000 µF. They are used in a wide variety of applications, including computers, consumer electronics, industrial automation, and automotive.ECE-S1CG472E is an aluminum electrolytic capacitor made by Elna. It is a mini size, surface mount device with a rated capacitance of 47µF, a voltage rating of 6.3V, and a temperature rating of up to 105°C. It is constructed with a metallized polypropylene dielectric with an on-chip electrostatic discharge (ESD) protection. It has a radial lead form factor and a radial lead length of 5mm. The ECE-S1CG472E is ideal for applications that require a small space-saving design and a high capacitance-to-volume ratio.The ECE-S1CG472E can be used in a variety of applications, including power supplies, converters and switching regulators, automotives, amplifiers, audio and video equipment, and medical equipment. It is suitable for blocking and decoupling applications in electronic circuits. The working principle of the ECE-S1CG472E is based on the principle of an electrochemical double layer capacitor. When a voltage is applied, an electric double layer forms between the electrodes (anodic and cathodic layers). The anode layer consists of aluminum, and its double layer consists of ions (anions) from the electrolyte and oxide ions on the surface layer of the aluminum. The cathode layer consists of a liquid electrolyte (electrolyte) and metal ions. This double layer stores the electric energy.When a charge is applied to an aluminum electrolytic capacitor, electrons are attracted and move from the cathode to the anode, forming a very thin layer of negative charge on the oxide film on the surface of the aluminum anode. This thin layer of negative charge is balanced by an influx of positive ions from the electrolyte. This layer of positive ions is thicker and thicker, creating a very large capacitance due to the large capacitance of these ions. This is how aluminum electrolytic capacitors store energy.The ECE-S1CG472E has a very compact and lightweight design, and its rated capacitance is 47µF. The aluminum electrolytic capacitor offers exceptional capacitance-to-volume ratio due to its high electrical double layer capacitance. In summary, the ECE-S1CG472E is an aluminum electrolytic capacitor with a small form factor and a large rated capacitance. It is suitable for applications that require a small space-saving design and a high capacitance-to-volume ratio. It can be used in a variety of applications, such as power supplies, converters and switching regulators, automotives, amplifiers, audio and video equipment, and medical equipment. It works based on the principle of an electrochemical double layer capacitor, and it stores electric energy in its anodic and cathodic layers.
