T491X686K020AT

T491X686K020AT is one of the type of tantalum capacitors, a type of electrolytic capacitors, which has wide range of applications and working principles in the industry. It is being used to control and filter the power supply in electronic equipment.

Tantalum capacitors are composed of two metallic plates, an anode, and a cathode, which are sandwiched between two dielectric layers. The plates, usually composed of metal or metal oxide, are separated by a porous dielectric layer. These capacitors are available in surface mount, through hole, and leaded configurations and feature various ratings for voltage, capacitance, temperature, and lifespan.

T491X686K020AT is designed to offer a combination of low ESR and high capacitance in one capacitance range. This combination provides a good electrical performance for the applications in low current and high frequency switching, storage and output performance. The capacitance range of T491X686K020AT is 6.8µF up to 170µF, and the voltage range is 4V up to 20V.

In terms of its working principle, the anode and the cathode of the capacitor works in a similar way with other forms of electrolytic capacitors electron flow. Electrons are formed on the positive electrode, and then travel through the electrolyte to the negative electrode. When the power supply is disconnected, no electrons can move between the electrodes, and the capacitor loses its charge. When a power supply is connected, electrons can move between the electrodes, and the capacitor regains its lost charge.

In terms of its application field, tantalum capacitors can be used in many different areas, such as in computers, telecommunications, medical electronics, and production equipment. There are also particular applications of T491X686K020AT, such as its use in automotive body control systems, and telecommunication for cellular base stations, GPS systems, and radar systems. In terms of its application in power supply filtering, the combination of low ESR and high capacitance of T491X686K020AT makes it suitable for applications such as AC/DC and DC/DC converters, DC/AC inverters, and battery powered equipment.

In short, the T491X686K020AT is one of the type of tantalum capacitors, designed to offer a combination of low ESR and high capacitance, and has wide range of applications, from computers, telecommunications, medical electronics, and production equipment to automotive body control systems, and telecommunication for cellular base stations, GPS systems, and radar systems. In terms of its working principles, the capacitor works in a similar way with other forms of electrolytic capacitors electron flow.
