Working Principle

The M39018/04-2148M capacitor operates on the principles of electrolytic capacitance, where two electrodes are immersed in an electrolytic solution. When a voltage is applied to the electrodes, an electric potential is created in the solution which affects the flow of ions. This is in turn helps to store a charge on the capacitor. This charge is the result of the attraction between ions and the electrodes. As the charge accumulates, the potential of the capacitor increases.

The capacitance of the capacitor is determined by the size and material of the electrodes. In the case of the M39018/04-2148M aluminum electrolytic capacitor, the two electrodes are made of aluminum foil. These electrodes are immersed in a solution containing water, electrolytes, and organic solvents. The size of the electrodes and the type of solution used will determine the capacitance of the capacitor.

The capacitor also has a dielectric that separates the two electrodes. The dielectric helps to prevent the electrodes from shorting out and also increases the capacitance of the capacitor. The dielectric used in the M39018/04-2148M is a polyester film. This provides the capacitor with the capacity to handle high voltage and frequencies.

The overall working principle of the M39018/04-2148M aluminum electrolytic capacitor is quite simple. When a voltage is applied to the electrodes, a charge is created in the electrolytic solution and this charge is stored in the capacitor. The dielectric helps to enhance the performance of the capacitor and allows it to handle high voltage and frequencies.

Conclusion

The M39018/04-2148M aluminum electrolytic capacitor is a versatile component with various applications in electronic circuits. It operates on the principle of electrolytic capacitance, where two electrodes are immersed in an electrolytic solution and a charge is created in the solution. The size of the electrodes and the dielectric used will determine the capacitance of the capacitor. The capacitor is ideal for high-frequency applications, high-temperature environments, and allows for AC filtering, RF bypass filtering, and electrochemical noise suppression.
