Tantalum Capacitors

T491A685K010AT4539 is a type of tantalum capacitor. It is a form of electrolytic capacitor, which is a polarized capacitor that contains two electrodes, a positive and a negative, immersing in an electrolyte. The electrodes consist of two different metals that form an oxide layer and function as the dielectric. The -10 represents the minimum capacitance tolerance of the capacitor which is 10%, and the 4539K indicates a rated voltage of 4.5V.

Application Field of T491A685K010AT4539

The T491A685K010AT4539 capacitor is primarily used to provide a local energy source in a circuit, such as being connected to the power line and circuit nodes in integrated circuits (ICs) or used as decoupling capacitors on power supplies. Additionally, it can be coupled with other components as a filter, or dissipate energy over a short-term and then recharge quickly.

Working Principle of T491A685K010AT4539

The tantalum capacitor T491A685K010AT4539 works on the principle of a capacitor and the concept of Coulomb’s law of electricity. It follows that when two insulated conducting surfaces come in contact with each other, a strong electrostatic force is generated. This same principle holds true for this type of capacitor. It has two conducting surfaces, such as the anode (positive terminal) and cathode (negative terminal), placed close together, and separated by an electrolyte. As electric current flows through the capacitor, electrostatic charge builds up on the capacitor’s electrodes, and this electrostatic charge is then stored in the capacitor.

When a capacitor is used to filter out the noise from a signal, the electric current coming in creates a buildup of electrostatic charge on the capacitor’s electrodes. This charge can then be used to filter out any unwanted noise, leaving behind a clean signal.

At the same time, when a capacitor is connected to the power line, it has the ability to store a significant amount of energy over a short period of time, and then quickly discharge that energy when needed. This can be used to provide a local energy source in a circuit.

Conclusion

The T491A685K010AT4539 is a type of tantalum capacitor. It is primarily used to provide a local energy source in a circuit. Additionally, it can be coupled with other components for noise filtering purposes. It works on the principle of a capacitor and the concept of Coulomb’s law of electricity. It has two conducting surfaces, such as the anode (positive terminal) and cathode (negative terminal), placed close together, and separated by an electrolyte. When electric current is applied, electrostatic charge builds up on the capacitor’s electrodes, and this electrostatic charge is then stored in the capacitor.
