The working principle of the 250USG390MEFCSN25X25 aluminum electrolytic capacitor is based on a Faraday principle. When an electric current is applied to the two electrodes of the capacitor, one electrode acts as a positive electrode, while the other works as a negative electrode. As a result, electrical charges accumulate on the two electrodes. This produces a potential difference between the electrodes that can store and discharge electric charge. When the voltage is increased by a certain amount relative to the initial voltage, the accumulated charges on the two electrodes begin to flow, and a capacitive current is generated.

The 250USG390MEFCSN25X25 is a reliable, high-performance aluminum electrolytic capacitor that is durable and cost-effective. It is ideal for PFC circuits and other high-voltage applications. The combination of its low ESR value with high voltage ratings makes it an ideal choice for a variety of applications.
