Working principle of UPJ2C220MHD aluminum electrolytic capacitor

The UPJ2C220MHD aluminum electrolytic capacitor is an active component, which belongs to a polarized capacitor. It has two electrodes, an anode and a cathode, separated by a dielectric material. The dielectric material is usually an oxide layer that is formed by applying a voltage to the capacitor. The anode of the capacitor is aluminum foil, and the cathode is aluminum or other electrolytic components connected to it. The oxide layer acts as a dielectric substance and provides an electrical insulation between the two electrodes. The electrolytic capacitor has a large capacitance, usually in the range of microfarads (μF). The greater the capacitance of the capacitor, the higher its voltage rating and the higher its energy storage capacity. Although electrolytic capacitors have a high capacity, their voltage rating is limited due to their construction.

When current passes through the UPJ2C220MHD aluminum electrolytic capacitor, a directional voltage is generated on the anode surface. This directs the dielectric layer to accumulate electrons in the anode and repel electrons from the cathode, resulting in a capacitance effect. This means that the current flow in the capacitor is one-way, from the anode to the cathode. When the current reaches the capacitor\'s voltage rating, the internal pressure of the capacitor restrict the current. This is why it\'s important to pay attention to the voltage rating (V) when selecting a capacitor.

Conclusion

The UPJ2C220MHD aluminum electrolytic capacitor utilizes the physical process of electrolytic to store energy. It is widely used in various fields with its low-leakage current, high-temperature resistance, and long-life characteristics. Its application fields include computer power supply, audio power amplification, laser equipment power supply, LED power supply and various industrial control power supply. And its working principle is based on the directional voltage generated by current passing through the capacitor, directing the dielectric layer to accumulate electrons in the anode and repel electrons from the cathode, resulting in a capacitance effect.
