Aluminum electrolytic capacitors are widely used in electronic products such as energy saving lamps, computer motherboards, car audio systems, and mobile phone power circuits. These capacitors have a variety of models, including ELXM251VSN391MR25S. This article will introduce the application field and working principle of ELXM251VSN391MR25S aluminum electrolytic capacitors.

1. Application fields of ELXM251VSN391MR25S aluminum electrolytic capacitor

ELXM251VSN391MR25S aluminum electrolytic capacitor is a type of polarized capacitor. It is mainly used in electronic circuits such as power supply and display circuit of wall washing machine, car audio system, mobile phone, and computer motherboard. It can be used in AC circuits or DC circuits, mainly used as smoothing circuit and HF circuit bypass capacitor.

2. Working principle of ELXM251VSN391MR25S aluminum electrolytic capacitor

ELXM251VSN391MR25S aluminum electrolytic capacitor works according to the principle of electrolytic condensation. It is composed of a cylindrical aluminum shell, an electrolyte (such as manganese dioxide), a separator, and two electrodes (cathode and anode). One of the electrodes is made of aluminum foil, and the other is made of aluminum oxide film. A liquid electrolyte is filled into the aluminum shell, and a separator is added to separate the two electrodes. When the capacitor is connected to the power supply, the electrons on the anode plate will transfer to the cathode plate through the electrolyte, and form an electric field that neutralizes the applied voltage. This electric field is called capacitive coupling, and it can store electrical energy.

3. Advantages and disadvantages of ELXM251VSN391MR25S aluminum electrolytic capacitor

The advantages of ELXM251VSN391MR25S aluminum electrolytic capacitor are that the capacitance value is large, stable and reliable, and the life span is long; the disadvantage is that it is bulky and easy to leak and short circuit in case of high voltage, high temperature or instability.

Conclusion

ELXM251VSN391MR25S aluminum electrolytic capacitor is mainly used in analogue and digital circuits of electronic equipment such as wall washing machine, car audio system, mobile phone, and computer motherboard. It works according to the principle of electrolytic condensation. Its advantages are that the capacitance value is large, stable and reliable, and the life span is long.
