Aluminum electrolytic capacitors, with the part number 25WXA680MEFC12.5X16 specifically, are polarized capacitors made of two aluminum foil conductors separated and insulated by a paper separator soaked with an electrolytic solution. Such capacitors are generally referred to as electrolytic capacitors, which are mainly used for storing charge and filtering signal. Usually, with polarized electrodes, aluminum electrolytic capacitors are available in very small in size and are usually used for applications for low-voltage, low-current circuits that require a large capacitance.The aluminum electrolytic capacitor 25WXA680MEFC12.5X16 has an extended application field in low voltage and low current circuits, delivering high capacitance within a limited space and with a low price. In addition, the capacitor is designed with a temperature range from -40°C~+105°C so that it can be used in various fields with fluctuating temperatures. Moreover, with a rated voltage of 6.3 VDC, a rated capacity of 680 uF, and a case dimension of 12.5x16mm, this capacitor can not only provide a maximum ripple current of 1.50 A, but also work with a wide range of temperature and voltage.The working principle of aluminum electrolytic capacitors lies in the electrolyte used. It bridges the anode foil and the electrolyte, while separating it from the cathode foil and forming a space between the anode and cathode foil. When a voltage is applied to a capacitor of this type, an electric current creates a thin layer of electric oxide formed on the anode that stores charge and allows the electrolyte bridge to transfer charge carriers. This is called the capacitor charge-discharge cycle.The capacitor\'s ability to store and discharge charge is dependent on the temperature of the environment in which it is used. As the temperature increases, the rate of oxidation (the formation of the electric oxide layer) increases as well. On the other hand, a decrease in temperature may cause oxidation to slow down, reducing the capacitor\'s ability to store and discharge charge.The 25WXA680MEFC12.5X16 aluminum electrolytic capacitor is also designed with a high frequency ripple current rating, which makes it suitable for use in filtering signals, such as in audio equipment. The capacitor performs this function by allowing high frequency ripple currents from a power supply to pass through it while absorbing the lower frequency signals, thereby reducing noise in audio systems.In conclusion, the 25WXA680MEFC12.5X16 aluminum electrolytic capacitors are specially designed for use in low voltage and low current circuits with temperature range from -40°C~+105°C. It can provide a wide range of temperature and voltage options while delivering high capacitance within a limited space and with a low price. The capacitor also features a high frequency ripple current rating, allowing it to be used in audio systems for noise reduction.
