Aluminum electrolytic capacitors, or aluminum electrolytic capacitors, alias electrolytic capacitors, are resistors composed of aluminium foil electrodes and solid electrolyte. The series number 35NA470MEFC12.5X25 is a type of aluminum electrolytic capacitor, with 470 uF capacitance, 1.5 V voltage, -40 to +105 Celsius temperature range, and 12.5 mm diameter. Aluminum electrolytic capacitors are ubiquitous in voltage stabilization circuits due to their large capacitance and small volume.

The application field of the 35NA470MEFC12.5X25 aluminum electrolytic capacitor mainly includes: DC power supply, power supply filter, AC power supply filter, dry type transformer, variable frequency power supply filtering, stepping motor drive, muffler filter machine and UPS power supply ect. This capacitor can be used for both audio and power circuits. Besides, the 35NA470MEFC12.5X25 capacitor is especially suitable for signal filtering capacitors in audio circuits to reduce signal distortion and improve sound quality.

In terms of working principle, when an external voltage is applied through an external circuit, a certain positive and negative charge will be driven on the surface of the two electrodes in the aluminum electrolytic capacitor. Due to the restriction of the electric double layer, the charges can only be accumulated to a certain degree, thereby generating a capacitance. The electric double layer is composed of aluminum foil and electrolyte, with an insulating oxide layer on the surface of the aluminum foil. The insulating oxide layer is formed through a special electrolytic oxidation process.

Under normal circumstances, the current generated by applying an external voltage is very small, as the electrical field strength in the electric double layer is excessively strong, making it extremely hard for electrons to penetrate the electrolyte on the surface of the aluminum foil. Moreover, the electric charge stored on the surface of the aluminum will not be dissipated or leaked, so that the capacitor can maintain the state of charge accumulation, forming capacitance.

In addition, the structure of the aluminum electrolytic capacitor is mainly composed of a rubber coated aluminum shell, a sealing o-ring, an aluminum foil anode, a separator, a coating solid electrolyte, and a negative electrode terminal. The aluminum foil anode is wrapped with a special dielectric paper separator soaked with a solid electrolyte, which can form a two-layer solid electric double layer structure. The electric charge accumulated in the electric double layer is called electric double layer capacitance, which can store large capacitance in a small volume.
