Aluminum electrolytic capacitors are essential components used to store electrical energy and provide a variety of specific uses in electronic circuits. The LLS1V123MELB series of aluminum electrolytic capacitors is introduced to address a range of these needs. This series of capacitors features a variety of voltage ratings and capacitances for a variety of uses.

Application Field

The LLS1V123MELB series is suitable for a broad range of applications such as filtering, time-constant, buffering, and energy storage. As a filtering capacitor, the device eliminates noise generated in the circuit and improves the signal-to-noise ratio. As a time-constant, the device is used in AC/DC and DC/DC converters, providing a stable voltage output. As a buffering capacitor, it can reduce the voltage drop caused by the load during the switch transition period. Finally, as an energy storage device, it provides a temporary energy to components when the current is insufficient.

Working Principle

The LLS1V123MELB series is a true aluminum electrolytic capacitor with an electric double-layer structure. It consists of two-layer electrodes absorbing and releasing electric charged, and an electrolyte consisting of anoxidized aluminum cathode foil and a manganese dioxide varistor slurry. Under normal conditions, the two-layer electrodes have opposite polarity and absorb an electric charge accordingly. When the opposite charge decreases or increases, the capacitor can either absorb or release charges depending on the requirements.

The aluminum electrolytic capacitor has good stability and long life. Due to the high capacitance and low equivalent series resistance, it also has low inductive loss and excellent frequency characteristics. Moreover, it has high ripple current capability, allowing it to absorb more energy. The LLS1V123MELB series complies with UL,VDE safety regulations and each device is internally protected with thermistor and/or varistor (MOV).

In conclusion, the LLS1V123MELB series has versatile uses across a wide range of applications. It is robust and long-lasting, and features excellent thermistor, varistor, and frequency characteristics. The capacitor complies with UL,VDE safety regulations, making it suitable for ruggedised applications.
