Tantalum – Polymer Capacitors
T520D227M004ATE012 is a type of polymer capacitor which is generally used in a range of different applications such as power management, digital electronics and audio. As tantalum-polymer capacitors have low ESR, high ripple current ratings and low temperature coefficients, they are often used in demanding applications such as automotive, military, space and aerospace applications.Components
T520D227M004ATE012 contain two kinds of materials – a tantalum electrolyte and a conductive polymer as dielectric. The electrolyte is composed of an aqueous solution of an alkaline or an acidic chemical, usually potassium hydroxide, sulfuric acid or lithium hydroxide. The other component, theconductive polymer, is a polymer material with the ability to absorb and transport ions. The combination of the two creates a capacitor that can be charged and discharged quickly, which makes it suitable for a variety of applications.Capacitance and Voltage Ratings
T520D227M004ATE012 has a capacitance rating of 47µF and a voltage rating of 20V. The capacitance rating indicates the maximum amount of charge that can be stored in the capacitor. The higher the capacitance rating, the higher the amount of charge that can be stored. The voltage rating indicates the maximum voltage that the capacitor can withstand before failing. It is important to select a capacitor that is capable of handling the voltage and current needs of the application.Application Field
T520D227M004ATE012 is primarily used for power management and audio applications. The low ESR and high ripple current ratings make it well suited for power management applications such as DC/DC converters and AC/DC converters. Furthermore, due to its low temperature coefficients, it is often selected for automotive, military, aerospace, and space applications. The high ripple current ratings also make it well suited for audio applications, such as amplifiers and pre-amplifiers.Working Principle
T520D227M004ATE012 is a type of electrolytic capacitor. When an electric current passes through it, the electrolyte acts as a receiver and transports ions to the electrodes. This charge storage process creates a potential difference across the capacitor, which is the opposite of the applied voltage. The amount of charge stored in the capacitor is determined by the capacitance rating and the applied voltage. The capacitance of the capacitor increases as the voltage increases.When it is connected to a circuit, the capacitor acts as an energy source and can supply both DC and AC current. The current is determined by the amount of charge stored in the capacitor and the resistance of the circuit. In DC circuits, the capacitor acts as a low-pass filter, allowing low-frequency signals to pass through while blocking high-frequency signals.In conclusion, T520D227M004ATE012 is a type of tantalum-polymer capacitor that is used in a variety of applications. It has a high capacitance and a high voltage rating, and it can handle high ripple current ratings. Its low ESR and low temperature coefficients make it well suited for demanding applications such as automotive, military, space, and aerospace. Furthermore, its low-pass filter characteristics make it suitable for audio applications such as amplifiers and pre-amplifiers.The specific data is subject to PDF, and the above content is for reference
