Working Principle of UPJ2A120MED1TD

UPJ2A120MED1TD is a type of aluminum electrolytic capacitor that utilizes the electrochemical reaction of aluminum foil and acid electrolyte. This capacitor has a positive and a negative plate, and the positive plate is made of aluminum foil which is anode and the negative plate is made of paper. Both plates are immersed in an electrolyte. When a voltage is applied across the capacitor, the ions from the electrolyte move toward the electrodes and electrochemical reactions occur.

The positive ions from the electrolyte are attracted to the anode (positive) aluminum electrode and a thin oxide film forms on the surface of the anode. This oxide film acts as a dielectric which insulates the two plates and it has a high capacitance. As the oxide film forms, the voltage across the capacitor increases until it reaches the rated voltage of the capacitor, at which point the current stops flowing.

High-voltage type UPJ2A120MED1TD aluminum electrolytic capacitors have larger electrolyte reservoir and longer fatigue life due to their bigger tank size and specially designed shape. This improves their high-pressure endurance and capacitance stability. The aluminum foil is formed according to the amorphous method which enhances their low impedance characteristics and makes them ideal for high frequency applications.

Conclusion

In summary, UPJ2A120MED1TD aluminum electrolytic capacitors are characterized by their high-reliability, low-impedance, and long-life performance, which make them suitable for a variety of applications. This capacitor is a great choice for circuits where low-impedance and high-reliability are required. Additionally, its high dielectric strength and good surge performance makes it a great choice for high-frequency applications.
