T520B476M008ATE035 is a type of tantalum-polymer capacitor. It is a two-terminal electronic component that consists of a metallized tantalum anode and liquid polymer electrolyte. It is applied in various specialized applications ranging from automotive electronics to general-purpose electronics. This tantalum-polymer capacitor is available in two different chip sizes; 6.3mm x 5mm and 10mm x 8mm.

Tantalum-polymer capacitors offer a number of advantages over traditional tantalum electrolytic capacitors. They are more stable and reliable, have increased capacitance density and higher ripple current ratings. The polymer also enables the tantalum-polymer capacitors to operate at higher temperatures compared to their electrolytic counterparts. The polymer also provides a higher dielectric strength enabling the capacitors to operate at higher voltages.

Tantalum-polymer capacitors are widely used in many applications due to their robustness and long lifetime. The capacitors are often used in automotive electronics, as filters in power supplies, and in decoupling and filtering circuits in audio and video equipment. The capacitors are also widely used in industrial equipment such as welding machines and solar installations and in medical technology such as medical imaging and diagnostics.

The working principle of the tantalum-polymer capacitor relies on a thin film of liquid polymer electrolyte sandwiched between two metallized tantalum anodes. The electrons flow from the negative anode to the positive anode and create an electrostatic field. This electrostatic force pushes the electrons onto the positive anode, resulting in the formation of a capacitor.

The capacitance of the capacitor is determined by the thickness of the polymer, the area of the plates, and the permittivity of the polymer - meaning that different combinations of materials can result in different capacitances. The voltage rating, on the other hand, is primarily determined by the permittivity of the polymer. The higher the permittivity, the higher the rated voltage.

Tantalum-polymer capacitors are able to handle large ripple currents, and have low ESR travel, low inductance and high temperature performance. They also boast a greater operating temperature range and a much longer operating lifetime compared to traditional tantalum electrolytic capacitors. With these advantages, tantalum-polymer capacitors are ideal for high temperature and higher frequency applications as well as for high capacitance density applications.

Tantalum-polymer capacitors are a robust and reliable component that is used in many applications. They are resistant to shock and vibration, and have high ripple current ratings that make them perfect for applications in automotive electronics and medical technology. The long lifetime and high temperature performance of the capacitors make them an ideal choice for power supplies and filter circuits.
