Aluminum electrolytic capacitors are widely used in diversified electronics due to their low cost, substantial capacitance and small size. The LGR2D391MELB25 is a type of aluminum electrolytic capacitors, which is known for its long life and high performance. Here, we will introduce its application field, working principle and advantages.

Application Field

The LGR2D391MELB25 is most suitable for use in industrial machinery, motors, high frequency power supplies, and power supplies where high ripple current and long life expectancy are required. It is also suitable for applications with capacitance requirements ranging from 0.1μF to 470μF.

Moreover, it is ideal for large ripple current applications such as PFC and VRM circuits, automotive power supplies, AC-DC converters, SMPS, power supplies and inverters.

Working Principle

The LGR2D391MELB25 consists of an anode foil and a cathode aluminum foil, which form the conducting material used for the carrier current. The electrolyte is an insulating liquid with a gel type viscosity that act as separator for aluminum foil plates. The separator and the electrolyte together constitute the core of the capacitor.

When voltage is applied to the capacitor, electrons flow from the anode foil to the electrolyte, producing a charge on the cathode foil and a current starts flowing into the surrounding circuit due to the capacitive effect. The aluminum electrolytic capacitors react very quickly in response to changes in the voltage, making them ideal for applications such as power supplies and invertors.

Advantages

The aluminum electrolytic capacitors are more affordable and reliable than other types of capacitors, while also offering better power management. Due to its increased capacitance and low equivalent series resistance (ESR), the LGR2D391MELB25 is considered to be the ideal solution for high frequency applications where voltage stability and current ripple control are necessary.

The aluminum electrolytic capacitors are also capable of providing a longer life span since it allows for higher ripple currents and low temperatures. With the combination of low ESR and low temperature, the aluminum electrolytic capacitors are considered to be one of the best solutions in terms of power supply stability, size and cost.

In addition, the LGR2D391MELB25 is rated for a long operation lifetime, from 2,500 to 5,000 hours at 85 degree Celsius, thus making it an ideal choice for stable applications for a longer period of time. This attribute makes it suitable for industrial equipment and power supplies that require a long useful lifetime.

Conclusion

The LGR2D391MELB25 is an aluminum electrolytic capacitor that offers a wide range of applications in industrial machinery, motors and other power supply applications. It is characterized by very low ESR, long life expectancy, high capacitance range and low temperature. The LGR2D391MELB25 has several advantages such as cost effectiveness, reliable and better power management. Taking all of this into consideration, it can be called a perfect reliable solution for all types of power supplies, providing a long life and high performance.
