Aluminum Electrolytic Capacitors

The LAQ2D271MELZ25 is an aluminum electrolytic capacitor, an electronic component composed of two aluminum foils with paper interleaving, used for filtering and energy storage in electrical circuits. It is especially used in power supplies, decoupling circuits, and low-frequency resonant circuits. The advantages of aluminum electrolytic capacitors are the large capacity of energy storage, the low equivalent series resistance, and the relatively low cost.

Application Field

The LAQ2D271MELZ25 is an aluminum electrolytic capacitor, a type of capacitor featuring high capacitance but somewhat limited voltage tolerance. It has a versatile application field because of its relatively low cost and high capacitance, compared to some other types of capacitors. It can be used for signal filtering, signal coupling, signal bypassing and energy storage in the fields of power supply, audio equipment, automotive electronics, general electronics, portable devices and telecommunications.

Working Principle

The LAQ2D271MELZ25 is an aluminum electrolytic capacitor, a type of capacitor composed of two aluminum foils interleaved with a paper separator and soaked in an electrolyte. When a voltage is applied, the positively charged ions of the electrolyte are attracted to the negative aluminum foil. This charge, in turn, creates an opposing electrical field, resulting in an electric field between the foils, which is referred to as the capacitance (capacitive reactance). The capacitance of the LAQ2D271MELZ25 can reach up to 1.9μF.

The LAQ2D271MELZ25 has a low equivalent series resistance (ESR), which is critical for the power supply stability and ripple current capability. The low ESR allows for largely improved capacitive reactance, and thus, a better stability. In addition, the aluminum electrolytic capacitor also has a low thermal coefficient, which ensures that the capacitance remains relatively stable over temperature.

Conclusion

In summary, the LAQ2D271MELZ25 is an aluminum electrolytic capacitor, an electronic component with high capacitance, low ESR, and low thermal coefficient. It has a versatile application field because of its relatively low cost and high capacitance, and can be used for signal filtering, signal coupling, signal bypassing and energy storage in the fields of power supply, audio equipment, automotive electronics, general electronics, portable devices and telecommunications.
