Aluminum Electrolytic Capacitors are a type of common electrical components used throughout the electronics industry. The LGU2Z681MELZ is just one variation of these components and it is heavily used due to its small size, high capacitance and long life. The application field and working principle of this particular capacitor model can be broken down and explained in the following ways.

Application Field and Use Cases

This particular capacitor model is a surface-mount technology (SMT) that offers a standard capacitance rating of 68uF and an ultra-low ESR of 0.34Ω. This makes it an ideal choice for circuit designers looking for a higher capacitance rating and a lower equivalent series resistance rating. Due to the small size and low cost of the LGU2Z681MELZ, it is a popular choice for use in distributed power supply systems, solar power systems, mobile phones and other applications. It is also an ideal choice for applications that require high-frequency switching, such as brushless DC motors, power supplies and ignition systems.

Package Structure

The LGU2Z681MELZ is housed in a 7.2mm x 7.2mm x 5.4mm package. It typically has two external contact terminal points that connect the capacitor to the rest of the circuit. It does not require any extra components for mounting. This makes it convenient for use in a variety of applications, including high-density boards and other applications where space is at a premium.

Electrical Characteristics

This capacitor model typically has a rated voltage of 6.3V, which means it can operate safely at most operating voltages. Additionally, it can handle reversed voltage up to 6V and ripple currents of up to 1350 mA. It also has a series connection resistance of 0.35 mΩ and an equivalent series resistance (ESR) of 0.34Ω. All of these specifications make the LGU2Z681MELZ an ideal choice for applications where space is at a premium and performance is the top priority.

Working Principle

The working principle of the LGU2Z681MELZ is fairly simple. There are two electrodes (anode and cathode) in this type of capacitor that are separated by an electrolyte material. An electrical charge is generated between the electrodes when a voltage is applied to them, which creates a potential difference. This potential difference enables the capacitor to store electrical energy that can be discharged by a current flowing through the capacitor at a later time.

Conclusion

The LGU2Z681MELZ is a popular aluminum electrolytic capacitor that is widely used in distributed power supply systems, solar systems, mobile phones and other applications due to its high capacitance rating, low equivalent series resistance, small size and low cost. This type of capacitor operates by creating a potential difference between two electrodes and storing energy in the form of an electrical charge that can be released when a current passes through it. To achieve the desired performance levels, it is important to consider the electrical characteristics of the LGU2Z681MELZ when selecting this model for use in a particular application.
