UPM1K470MPD1TA

Aluminum electrolytic capacitors are widely used in electronic products, and the UPM1K470MPD1TA is a popular type with many advantages. It offers high performance and reliable operation under a wide range of conditions and relatively low manufacturing costs. In this article, we will explore the application field and working principle of this aluminum electrolytic capacitor.The UPM1K470MPD1TA is mainly used as a power-source filter or noise filter in general electronic devices. It is highly effective at preventing the electronic parts from noise generated by AC power sources, as well as from electromagnetic interference. This aluminum electrolytic capacitor is also commonly used as a bypass capacitor in AC power supply, which helps to reduce AC ripple voltage.Additionally, this aluminum electrolytic capacitor can also be used for circuits with low-frequency oscillations, and the low ESR (equivalent series resistance) and low leakage current of UPM1K470MPD1TA make it suitable for use in low-frequency active circuits, as it can reduce the influence of frequency on the time delay.The working principle of UPM1K470MPD1TA is based on Faraday\'s law of induction, which states that a voltage is induced across a condenser when electric current changes over time. UPM1K470MPD1TA is composed of two aluminum foil plates separated by a paper insulating sheet soaked in an electrolyte. The electrolyte prevents electric current from passing through the device and provides a medium between the two plates with low dielectric loss.Generally, when electric current passes through one aluminum foil plate, it induces a voltage across the other plate, and the voltage is equal to the product of the current and the capacitance. As the applied voltage increases, the electric field intensity between the two plates increases, resulting in a current flowing through the electrolyte, which then produces an additional voltage drop. This phenomenon is known as alternating leakage current.In conclusion, the UPM1K470MPD1TA aluminum electrolytic capacitor is widely used in a variety of electronic devices, primarily in power source filtering and noise filtering circuits. It works on the basis of Faraday\'s law of induction, and its low ESR and low leakage current allow it to be used in low-frequency active circuits.
