Aluminum electrolytic capacitors are electrical components that use an aluminum oxide film as the dielectric to store electrical energy in a capacitor, also called a condenser. Aluminum electrolytic capacitors are suitable for applications with large capacitance values and low voltage requirements. The RFS-63V471MK8#5 is a type of aluminum electrolytic capacitor designed for use in high frequency circuits and high current circuits. Construction and CharacteristicsThe RFS-63V471MK8#5 is an axial-lead aluminum electrolytic capacitor, meaning that the leads are soldered on both sides of the aluminum case. In terms of construction, the component is composed of a solid anode – made of either aluminum or tantalum – and an electrolyte soaked separator. The anode is separator is composed of a non-woven paper, which is polarized and soaked in a liquid electrolyte, such as sulfuric acid. The leads are connected to the anode and the electrolyte is in contact with the separator. The RFS-63V471MK8#5 is designed to operate at a specific voltage and a predetermined frequency. This capacitor has an operating temperature range of -40 to +85 degrees Celsius and a rated capacitance of 470 µF. The capacitor also has a capacitance tolerance of ±20%, a rated voltage of 63V, a maximum ripple current of 680mA and a leak rate of 3.5MΩ. It is rated for 2,500 hours of life at an ambient temperature of 85 degrees Celsius. Application Field and Working PrincipleThe RFS-63V471MK8#5 is typically used in high frequency and high current circuits, such as switching power supplies and other power electronics applications. Typically, it is used to filter the direct current (DC) and filter out the high-frequency noise that may interfere with the circuit’s operation. The capacitor also provides output stability in critical applications. Due to its robust construction, the capacitor can also be used for a wide range of alternating current (AC) applications.When electrical energy is applied to the capacitor, an electric field is established between the anode and the electrolyte. This electric field causes an electrochemical reaction, which causes positive charge to flow from the anode to the cathode. As current flows through the capacitor, the capacitance increases, allowing more current to flow and resulting in a lower voltage drop across the circuit. As the capacitor is in a charging state, the internal components will expand and the capacitance of the capacitor will increase. ConclusionThe RFS-63V471MK8#5 is an axial-lead aluminum electrolytic capacitor suitable for high frequency and high current applications. It is designed with a solid anode, non-woven paper separator, and sulfuric acid electrolyte soaked in contact with the leads. The capacitor has a rated voltage of 63V and a maximum ripple current of 680mA. The capacitor is used to filter out high frequency noise and provide stability to the circuit.
