Tantalum capacitors are a specific variety of capacitor, which are either solid or electrolytic. They are composed of two components, the positive terminal, or anode, and the negative terminal, or the cathode. The material of choice for this type of capacitor is tantalum, hence the name.

T491A155K020AT4539 are a type of capacitors that are used in many applications. These capacitors have a large capacitance value of 155 μF and a low impedance of 45μΩ over a wide frequency range. They have a small size, making them popular in small electronics. The capacitor also has a high temperature coefficient of -20 mV/°C and a low ESR of 39mΩ.

The application fields of the T491A155K020AT4539 capacitor can include circuit decoupling, high voltage charge pump regulators, energy storage, filtering, and pulsed current applications. This particular capacitor can also be used as an energy storage device for power management and current conversion, as well as for reducing high-frequency noise in power supplies.

As for the working principles of T491A155K020AT4539 capacitors, they operate by storing electrical charge in a dielectric material. This dielectric material is situated between two charged plates, which are the anode and the cathode. When the capacitor is charged, the potential of the two plates increases, forming an electrostatic force. When the voltage across the capacitor is removed, the stored charge gradually reduces, discharging the capacitor.

These capacitors also function by providing a path to allow current to flow in only one direction while at the same time blocking in the opposite direction. This is due to the ability of charge carriers to move freely in one direction and not the other. Their ability to block and store energy with a low amount of dissipation makes them very reliable.

The T491A155K020AT4539 capacitors are versatile, offering various advantages in terms of size, capacitance, temperature coefficient, ESR and frequency range. As such, they are ideal for a wide variety of applications in the area of electronics, from filtering and energy storage to power management and current conversion.
