Tantalum capacitors are a type of capacitors consisting of two electrodes separated by a dielectric material. They are commonly used in electronic circuits and systems as energy storing components, because of their high capacitance, low profile, and relatively low cost. The 595D686X0020D2T is a type of tantalum capacitor specifically designed for high voltage and high temperature applications. Its physical characteristics and working principle are discussed below.

Physical Characteristics

The 595D686X0020D2T is a cylindrical electrolytic capacitor, which is sealed in an aluminum tube and has a metallic finish, with a black plastic coating for insulation. The main body of the capacitor is composed of two electrodes which are separated by a dielectric material. In order to ensure a good contact with the electrodes, the bottom of the capacitor is potted in to a moulded insulator. The capacitor also comes with a ripple filter for preventing high frequency noises. The total size of the capacitor is 8 mm x 29 mm, with an operating temperature range of -55 to +85 degrees Celsius.

Working Principle

The 595D686X0020D2T works according to the principles of electrostatics. When the capacitor is charged, the electric field generated between the two electrodes creates an electrostatic pressure which forces electrons towards a dielectric material, which, in turn, stores the electrons within the capacitor. When a current is applied, the stored electrons will create a positive charge on the first electrode, and a negative charge on the second electrode. As a result, an electric current is generated and the capacitor will discharge. The maximum voltage that the capacitor can handle is 20 Volts.

Application Field

The 595D686X0020D2T is mostly used in applications where high voltage and high temperature are needed. The capacitor is often used in high power circuits, such as motor drives, welding, and power supplies, due to its high voltage withstand capability. Its low profile and small size enable the capacitor to be used in small precision equipment and portable devices. The capacitor is also suitable for use in computer motherboards, portable radios, and LCD backlights, due to its wide operating temperature range.

Conclusion

The 595D686X0020D2T is a type of tantalum capacitor specifically designed for high voltage and high temperature applications. Its compact size and wide operating temperature range makes it suitable for use in small precision equipment and portable devices. The capacitor works according to the principles of electrostatics, in which the electric field generated between two electrodes create an electrostatic pressure, which is then stored within the dielectric material. The 595D686X0020D2T is mainly used in applications where high voltage and high temperature are needed.
