Aluminum electrolytic capacitors are widely used in many electronic circuits, such as power lines and audio equipment. The LKG2A681MESYAK is a popular aluminum electrolytic capacitor from the Japanese manufacturer Nippon Columbia. This capacitor is mainly used in audio systems in order to filter or smooth out the audio signal from the power supply. The LKG2A681MESYAK has a capacitance rating of 6800µF and an operating temperature range of -55°C to 85°C. The stack-up of the plates is also an important factor to consider when selecting a capacitor. The LKG2A681MESYAK has one plate of aluminum and one plate of a manganese dioxide dielectric, which helps reduce the ESR (Equivalent Series Resistance) and minimize impedance at high frequencies.

The working principle of the LKG2A681MESYAK is based on the electrolytic process. It consists of two aluminum electrodes covered in an electrolyte solution. As a voltage is applied across the capacitor, the electrolyte undergoes a chemical reaction, which forms an insulating oxide film on both the plates. As the voltage increases, the insulating oxide layer thickens and the overall capacitance increases. This is known as the “electrolytic effect”. The capacitance of the capacitor is also affected by temperature, so it is important to ensure the capacitor operates in an optimum temperature range.

The LKG2A681MESYAK is often used as a power supply filter in audio circuits. It helps reduce the amount of power line noise and hum that can be heard in the audio signal. It can also be used as a tone control, allowing the user to adjust the bass and treble frequencies of an audio signal. In addition, the capacitor helps to prevent voltage spikes and ensure smooth, even power delivery to the audio components.

The LKG2A681MESYAK is a reliable and cost-effective choice for a wide range of audio applications. Its unique design and construction make it ideal for high-temperature and low-voltage applications. The reliability and performance of this capacitor make it an ideal choice for many audio applications.
