Aluminum Electrolytic Capacitors

400RX304R7MT810X16 application field and working principle

Aluminum electrolytic capacitors, also known as electrolysis capacitors, aluminum electrolysis capacitors, aluminum electrolytic capacitors, which are divided into radial lead type, screw terminal (API) type, snap lead type and snap in type. They are widely used in communication equipment, office automation equipment, power tools, measuring instruments, computers and other electronic products.

Aluminum electrolytic capacitors have many advantages, such as small size, high volume ratio, low initial leakage current, large capacity range, wide temperature range and long service life. Therefore, they are widely used in various kinds of electronic products.

The 400RX304R7MT810X16 is an aluminum electrolytic capacitor specifically designed for low-frequency, low-voltage applications. Its capacitance ranges from 0.1 to 500 μF and working voltage from 1.5 to 250 V. It is widely used in voltage regulators, filters, AC/DC signal decoupling and anti-interference circuits.

The working principle of aluminum electrolytic capacitor is the same as that of most other capacitors: it uses the Coulomb force to maintain the voltage in the capacitor. According to the law of electrostatic attraction and repulsion, when a positive charge is sent to the positive electrode of the capacitor, the negative charge of the electrolyte will move toward the negative electrode, and the electrostatic field generated will make the space between the two electrodes(anode and cathode) charged.At this time, the electric field will not decrease with the increase of charge, but will maintain the electric field between the two electrodes and the electric potential difference.

When the capacitor is connected with the power supply, the capacitor\'s electric field maintains the charge balance in the capacitor. When the capacitor is connected with the circuit, the capacitor works on the AC circuit. Under the alternating current, the positive and negative charges flow between the anode and the cathode of the capacitor repeatedly. The filtering function of the capacitor can reduce the current of the alternating current, so as to achieve the purpose of signal filtering.

Due to the higher capacitance, smaller volume, large working voltage range, wide working temperature range and longer service life, 400RX304R7MT810X16 aluminum electrolytic capacitors are widely used in low-frequency, low-voltage applications, such as voltage regulators, filters, AC/DC signal decoupling and anti-interference circuits.
