Aluminum electrolytic capacitors are one of the most commonly used capacitors in the electronic circuit. They are widely used in a variety of industries for a variety of applications due to their large capacitance and low cost. The LGN2G101MELY30 is a type of aluminum electrolytic capacitor developed by Murata, a Japanese electronics manufacturer. The purpose of this article is to explain the application field and working principle of these capacitors.

Application Field

Aluminum electrolytic capacitors are commonly used to provide a higher capacitance than normal film or ceramic capacitors. They are mainly used in power supplies, to protect amplifiers and motor controllers, to reduce noise and filter the AC ripple in switch-mode power supplies, and to provide a DC bias in transducer circuits. Murata\'s LGN2G101MELY30 is a popular choice for these applications because of its high capacitance and low cost.

The LGN2G101MELY30 is also used in a variety of other applications, including radio circuits, sensor circuits, digital signal processing, inductor-capacitor (LC) resonance circuits, medical equipment, consumer products, and communication systems. This capacitor is also popular in automotive circuits, where it is used to filter spikes, absorb electrostatic discharge, and reduce switch-mode power supply noise.

Working Principle

The LGN2G101MELY30 is an aluminum electrolytic capacitor featuring a sealed solid electrolyte. Its construction consists of a cylindrical anode made from aluminum foil, a separator made from either paper or polyester film saturated with electrolyte, and a cathode made from aluminum. This capacitor has a polarized construction, with the positive terminal connected to the anode, and the negative terminal connected to the cathode.

The working principle of the LGN2G101MELY30 is based on adding a thin oxide layer to the anode using an electrolytic solution. This thin oxide layer increases the capacitor\'s surface area and increases its capacitance. When a voltage is applied across the terminals, the oxide layer acts as a dielectric material, storing the electrical energy.

The LGN2G101MELY30 has a capacitance of 1000 µF with a maximum operating voltage of 16 volts. It is also resistant to a wide range of temperatures, from -40°C to +105°C. Additionally, it is TÜV-certified and RoHS-compliant, making it an excellent choice for high-reliability applications.

Conclusion

In conclusion, the LGN2G101MELY30 is a popular aluminum electrolytic capacitor used for a variety of applications, due to its large capacitance, low cost, and reliability. Its working principle is based on adding a thin oxide layer to the anode which acts as a dielectric when a voltage is applied across its terminals. Murata\'s cutting-edge technology ensures that this capacitor is built to exacting standards and is suitable for use in a wide variety of applications.
