Tantalum capacitors are an important component used in a wide range of applications for modern electrical and electronic equipment. Tantalum capacitors are used for energy storage and voltage stabilization and provide a wide range of features, from high capacitance and low leakage current to small size, low ESR (Equivalent Series Resistance), and high frequency applications. T491X336M035AT is a specific model of tantalum capacitor, which is featured with excellent mechanical robustness and higher capacitance. In this article, we will discuss the application field and working principle of T491X336M035AT.

T491X336M035AT has a diameter of 4.97x3.56mm and a low ESR of 0.009Ω. It is a low-leakage automotive-grade capacitor, providing a high reliability and temperature endurance of -55°C to 125°C. The dissipation factor and avalanche voltage are also very good, respectively, 1.0x10-4 to 1.1x10-4 and 45V. The capacitance ranges from 0.015uF to 560uF, and its maximum working voltage is 16V.

Due to these characteristics, T491X336M035AT is mainly used in the automotive and industrial applications, such as avionics, industrial electronics, and medical devices. They are also used in LED lighting, LED driver, power management, DC-DC converters, AC-DC power supplies and high-precision control boards.

T491X336M035AT is a type of polarized capacitor, which is made up of two electrodes, generally with a small distance between them. It works by storing the potential energy in the electric field between the two electrodes when the voltage is applied. When the voltage is removed, the stored energy will be released.

The T491X336M035AT capacitor consists of a tantalum anode, a solid, anodic oxide layer, an electrolyte and a conductive material. The anode is made from a tantalum-based powder, which is compressed and formed into the desired shape. Once sintered, it is inserted into the capacitor case. Once in the case, a thin film of anodic oxide is formed on the surface of the anode by anodization process. The electrolyte is then added and a conductive material is layered over the electrolyte. The combination of the two is what forms the cathode of the capacitor.

During operation, the anode and cathode are connected to the electrical circuit. The anode is positively charged, while the cathode is negatively charged. When a voltage is applied, the capacitance occurs between the two electrodes, which allows current to flow between them and the circuit. This current flow iswhat stores the energy in the electric field.

When the voltage is removed, the stored energy is released and current flows in reverse direction. The reverse current then gets discharged and the capacitor is backto its initial state.

In conclusion, T491X336M035AT is a classified tantalum capacitor which is widely used in many automotive and industrial applications. Its excellent mechanical robustness, low ESR and higher capacitance make it an ideal capacitor for these applications. In addition, the working principle of the tantalum capacitor is also quite simple. It works by storing the potential energy in the electric field between the two electrodes when the voltage is applied and releasing the energy when the voltage is removed.
