Tantalum capacitors are a type of electrolytic capacitor which use tantalum as the anodic material. Their most important characteristics are small size, high capacitance, low ESR and low leakage current, making them particularly suitable for high frequency and low voltage applications. They have become increasingly popular in a wide variety of electronic designs due to their high reliability, long life and low cost.The T491D476M020AT4820 is a radial leaded, non-solid electrolytic, tantalum capacitor. It is a surface-mounted device (SMD) with a capacitance of 47µF and a low Working Voltage of 6.3V DC. It is suitable for use in computer, telecommunications, automotive and aerospace applications that require high reliability, low ESR and low leakage current.The tantalum capacitor has two basic components, an electrolyte and a cathode. The anodic material (tantalum) is etched onto the surface of the cathode to form the anode, while the electrolyte is deposited in between them. The two components are then sealed with a dielectric layer. In the T491D476M020AT4820, this is usually an anodized aluminum layer, which acts as a barrier to enable the capacitor to function.The basic working principle of a tantalum capacitor is that of a simple capacitor. When a voltage is applied across the terminals, current will flow through the electrolyte to the anode and then back to the cathode. This flow of current is what creates the capacitance of the device. The capacitance of a tantalum capacitor is measured in Farads (F), and represents the ability of the device to store electrical energy.The T491D476M020AT4820 is a high reliability, surface mounted tantalum capacitor that is commonly used in industrial, automotive and aerospace applications. This capacitor is rated for a maximum operating temperature of 85°C and has a very low ESR of only 0.25 Ohms. It is also highly resistant to shock and vibration, making it an ideal choice for military, telecom and aerospace applications where reliability and durability are of the utmost importance.The T491D476M020AT4820 is also utilized in smaller scale applications, such as in computers and consumer electronics. Its small size, low ESR and excellent temperature stability makes it suitable for use in circuit boards and battery-powered portable devices that require high capacitance, low ESR and low leakage current.In summary, the T491D476M020AT4820 is a high reliability, surface mounted, tantalum capacitor. It is a very popular choice fora wide range of applications due to its low ESR, high capacitance and excellent temperature stability. It is particularly useful in military, telecom and aerospace applications, but is also suitable for use in computers and consumer electronics.
