Tantalum capacitors are used in a wide array of electronic applications and are designed to store energy in a much lower profile than other types of capacitors. This often makes them a preferred choice for applications with limited space available for components. The T491D156M035AT is a common type of tantalum capacitor manufactured by AVX Corporation.The T491D156M035AT is a high-end tantalum capacitor with excellent performance. It is a multilayer type of capacitor constructed from an anodized tantalum foil sandwiched between two dielectrics made from a leakage reducing material. The dielectric material is typically an organic material such as polyethylene naphthalate (PEN). A typical body forming the capacitor is a slug of susceptible manganese dioxide (SMD) that is coated with an electrically conductive layer. The body is then soldered to the end of a tantalum or manganese lead. The capacitor is then housed in a cylindrical or a rectangular metal case.The T491D156M035AT is an especially popular tantalum capacitor due to its high-performance properties. It features a capacitance range between 15 and 1,000µF, an equivalent series resistance that ranges from 0.15 Ohms to 20 Ohms, and a maximum leakage current between 0.001µA and 0.004µA. The T491D156M035AT also has a maximum working voltage between 25 and 35V, and a maximum ripple current of 350mA. These properties make it well-suited for power application, such as for applications with high-speed switching.Due to its properties, the T491D156M035AT is typically used for a wide array of applications, including power supplies and audio amplifiers. It is also widely used in storage devices such as mobile phones, computers and other portable electronics. The capacitor is also commonly used in high-performance automotive components, telecommunication systems and military applications.The T491D156M035AT works on the principle of capacitance. A capacitor is an electrical element made up of two conductive plates (or conductors) separated by a dielectric material. When an electrical current is applied to the plates, the capacitor will store energy in the form of an electrostatic field between the two conductive surfaces. When current is removed, the capacitor will discharge, releasing stored energy.In the case of the T491D156M035AT, the capacitor stores energy in the form of an electrostatic field. The capacitor’s high-performance characteristics give it greater storage capacity, longer life and reliable performance even under high temperatures and extreme conditions. This makes it an excellent choice for applications requiring high levels of performance and reliability.In conclusion, the T491D156M035AT is a high-performance tantalum capacitor. It is widely used for a variety of applications in the electronics, automotive, telecommunication and military industries. The capacitor stores energy in the form of an electrostatic field, allowing for greater storage capacity and longer life. Its performance makes it an excellent choice for applications requiring high reliability.
