Due to its low ESR and temperature coefficient, its also suitable for voltage conversion and switching applications.

Working Principle of 6TPE220MAZB

The 6TPE220MAZB is a chip type of polymer-tantalum capacitor. It has two electrodes. One is a tantalum anode which is encapsulated in a conductive polymer, and the other is a cathode which is usually made of aluminum. The anode is electrically connected to the ceramic body, while the cathode is electrically connected to the lead which protrudes from the capacitor.

When a voltage is applied to the capacitor, an electric field is created between the electrodes. This causes electrons to be attracted to the cathode, thereby forming a layer of electric charges on the tantalum anode. As a result, the capacitor stores electrical energy, and a current is generated when the voltage is removed. Once the voltage is removed, the electrons drift back to the anode and the capacitor returns to its original state.

In typical applications, the 6TPE220MAZB can handle high frequency and pulsed signals, which makes it suitable for power conversion, high frequency rectification circuits, and DC-DC switching applications. Additionally, its low ESR and temperature coefficient allows it to be used in high reliability circuits.

Conclusion

The 6TPE220MAZB is a high-performing and reliable capacitor. Its hermetically sealed ceramic container as well as its low ESR and temperature coefficient make it ideal for a wide range of applications. Its many applications include mobile phones, precision instruments, medical equipment and high frequency rectification circuits. Its working principle is based on the electric field generated between the two electrodes, which creates a layer of electric charges on the anode.
