Aluminum Electrolytic Capacitors and SLPX471M220C3P3

Aluminum electrolytic capacitors are a type of electrochemical capacitors that have a liquid electrolyte, usually an organic liquid, as well as an anode foil and porous gasket made of materials like aluminum and tantalum. The capacitor utilizes anodic oxidation of the aluminum anode to generate vast areas of oxide coating on its surface, which has a much higher dielectric constant than air. This layer acts as a dielectric material to facilitate charge storage. Aluminum electrolytic capacitors are very cost-effective and offer decent capacitance values, and hence are widely used in the industry for a wide variety of applications. SLPX471M220C3P3 is a model of aluminum electrolytic capacitor designed and manufactured by Sunlord Electronics Technology Co., Ltd. Generally, this type of capacitor has a voltage tolerance of 6.3V-200V and is made of radial leaded aluminum. The other dimensions of this aluminum electrolytic capacitor are 5mm (±0.3mm) x 8mm (±0.2mm). SLPX471M220C3P3 has a standard capacitance of 4.7μf (±20%) and an endurance of 3000 Hrs. Therefore, this capacitor is rated for a temperature range of -25°C to +85°C. In addition, this aluminum electrolytic capacitor has a low failure rate as it has passed rigorous testing. SLPX471M220C3P3 is mainly used in power management circuits, where large capacitance is needed. These aluminum electrolytic capacitors are often used as input and output filters for switching mode power supplies (SMPS). In SMPS applications, the input filtering components prevent high frequency noise from entering the application while the output filter components reduce the voltage ripple and inrush current. Additionally, SLPX471M220C3P3 also finds uses in numerous applications such as motor control circuits, noise filter, etc. The working principle of the SLPX471M220C3P3 is similar to that of any other aluminum electrolytic capacitor. When DC voltage is applied to the capacitor, a barrier layer is created by the anodic oxidation process at the two electrodes, and the aluminum forms an insulating layer that prevents current flow. This layer acts as a dielectric material and helps to store the electric charge and increase the capacitance. As the voltage across the capacitor increased, more electrons will be pushed into the cathode, forming more layers of insulation and increasing the capacitance of the capacitor. Moreover, when the capacitor is discharged, the anodic layer flakes off allowing the electrons to return to the anode and the capacitance decreases. In conclusion, SLPX471M220C3P3 is a reliable and cost-effective aluminum electrolytic capacitor that offers reliable performance and long service life. The SLPX471M220C3P3 capacitor is mainly used as an input/output filter in SMPS applications and its working principle is based on the principle of electrochemical capacitance. Moreover, this capacitor is rated for a temperature range of -25°C to +85°C and has a low failure rate due to rigorous tests performed.
