Aluminum electrolytic capacitors are widely used in electronic circuits of various fields because they have the characteristics of high capacitance and small size. Among them, UPJ1E680MED1TD aluminum electrolytic capacitors are one of the important components for the development of modern information technology. This article will focus on the application field and working principle of UPJ1E680MED1TD aluminum electrolytic capacitor.

In the field of electronic technology, UPJ1E680MED1TD aluminum electrolytic capacitors often serve as energizing capacitors and filtering capacitors. The energizing capacitor is mainly used to directly provide energy to the active part of the circuit, such as vacuum tube filaments, which need to start and extinguish constantly, so the capacitor can be used in series to prevent the current from forming a loop. The filtering capacitor is mainly used for LC low-pass filter. The combination of inductor and capacitor can form a variable impedance, which can effectively suppress the high frequency signal or harmonics in the circuit, such as the anti-interference of power supply.

In addition to the above functions, UPJ1E680MED1TD aluminum electrolytic capacitors can also be incorporated into the resonance circuit. The resonance circuit can be used to oscillate or amplify the radio frequency signal to improve the circuit performance. It can also be used to modify and transmit the audio frequency signal, thereby achieving the effect of sound fidelity improvement.

In terms of its working principle, it is mainly composed of two electrodes of aluminium and electrolyte, in which the positive and negative electrodes will form a thin oxide film. This oxide film can store electricity, like a battery, and has the function of capacitor. When the capacitor is energized, a certain DC voltage will be applied, sliding the interface between the two electrodes and forming an internal capacitor in the device.

When the DC voltage is removed, a certain amount of electric charge can still be stored, which is the self-polarization effect of aluminum electrolytic capacitors. This self-polarization can make the oxide film of the diaphragm be constantly reinforced, and when the external pressure changes, the electric capacity of the capacitor also changes correspondingly.

In summary, UPJ1E680MED1TD aluminum electrolytic capacitors play an important role in modern electronic circuits. It can be used as an energizing capacitor, filtering capacitor and resonance circuit, which can effectively improve the performance of electronic circuits. Moreover, it adopts the principle of self-polarization, and its electric capacity can be adjusted with the external pressure, thus adapting to the needs of different working environments.
