Tantalum capacitors are widely used in electronic products due to their excellent combined properties of high capacity, low equivalent series resistance (ESR), low leakage current, and high frequency characteristics. The TAJW227M004RNJ is a surface mount, solid tantalum capacitor that is mainly used for applications that require long life and reliability.

The TAJW227M004RNJ construction includes a chip tantalum cathode, a tantalum anode, and an anode to cathode dielectric. The capacitance of this model is 22?F with a maximum working voltage of 4V. It has a rated insulation resistance of 1000M? at 100V DC, a maximum loss tangent value of 0.1% (1kHz) and a maximum dissipation factor of 0.02%.

The main application of the TAJW227M004RNJ is in high frequency power supplies, such as the portable power supplies needed for mobile devices. These applications often require a long life, with the TAJW227M004RNJ providing up to 2000 hours at 85°C / 85% RH. Its very low ESR and leakage current of just 2.5?A also makes it suitable for power circuits.

As with all capacitors, the TAJW227M004RNJ works on the principle of storing charge on the plates and then releasing it as a potential difference across the capacitors. This potential difference creates an electric field between the plates which creates a continuous current or charge in an electronic circuit. Thus it smooths out the voltage fluctuations and helps ensure that the required current is properly delivered to the load.

In conclusion, the TAJW227M004RNJ is a surface mount, solid tantalum capacitor with a capacitance of 22?F and a maximum working voltage of 4V. Its main application is in high frequency power supplies and it provides a range of characterictics such as a long life and very low ESR and leakage current. It works on the principle of storing charge on the plates and then releasing it as a potential difference to provide current to the circuit.
