Tantalum capacitors are kind of low equivilent series resistances capacitors, which are mostly used in smaller size than the aluminum electrolytic capacitors. T491X156M035AT is one of the most popular product of the tantalum capacitors. It is characterized by its high volumetric efficiency and big capacitance.

T491X156M035AT is typically used in decoupling applications, as well as sample and hold values and charge pumps due to its high frequency response. It is also often used in space sensitive applications where size is more important than power. It is especially used multi-anode devices.

The basic operating principle of the T491X156M035AT capacitor is simple. A thin sheet of tantalum with a dielectric oxide layer is placed between two electrodes—the anode and the cathode. When a voltage (voltage differential) is applied across the plates, electric charges are stored within the oxide layer. This creates an electric field across the dielectric and stores energy within the capacitor.

For the most common types of tantalum capacitors, the anode foil consists of pure tantalum surrounded by a protective layer of tantalum pentoxide (Ta2O5), which acts as an insulation layer. The Ta2O5 layer is usually around 5 μm thick on each side. Between the anode and the cathode of a tantalum capacitor is an electrolyte, usually either aqueous solution or some type of organic solvent. The most common electrolyte is a manganese dichloride-based solution.

The anode and cathode are connected with electrodes and the whole device is sealed in a suitable container depending on the size and the application. The capacitance of the device is determined by the thickness of the oxide layer and the size of the electrodes. It is related to the dielectric constant of the oxide and the area of the electrodes.

T491X156M035AT is a relatively high voltage capacitor and is built to withstand the higher stresses imposed by such voltages, so it is just as suited for all types of consumer electronics, automotive and industrial applications. The rated capacitance of T491X156M035AT is 0.15uF, which makes it fairly compact. Its temperature range is -55°C to +125°C and its rated voltage is 16V. The maximum operating temperature for T491X156M035AT is +85°C.

Due to its features, such as high volumetric efficiency, big capacitance, higher voltage capability and low ESR, T491X156M035AT is popularly used in a variety of industries, from consumer electronics to aviation, automotive and military applications.

In conclusion, the T491X156M035AT capacitor is a useful and versatile device which can be used in a wide range of applications due to its unique size, stability, high current and low ESR. It is an essential component in many electronics and mechanical systems, helping them function smoothly and accurately.
