Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are an essential component in a variety of electrical and electronic circuits. These capacitors have high capacitance and low impedance, which make them suitable for use in AC and DC circuit load application. The specific capacitor model of 63YXG330MEFC12.5X25 is designed for application fields such as power supply filter, PFC, rectifier, DC-DC converter, etc. This model provides excellent noise suppression and temperature stability properties.

Application Fields

The 63YXG330MEFC12.5X25 aluminum electrolytic capacitor is designed for application fields such as power supply filter, PFC, rectifier, DC-DC converter, etc. They are designed for use in circuits that handle high current and high voltage. They are also suited for power supply and rectifier circuits, as they are able to store and release energetic charges from one side of the circuit to the other. They have high ripple current ratings, which allow them to explain the noise between power sources.

The capacitor has a long lifetime and is reliable due to its low ESR and low internal impedance, which have been optimized to stabilize the current flow. Additionally, the capacitor has been tested to withstand high temperatures, up to 105°C, withstanding high system temperatures without any breakdown, able to provide inrush current during startup and long-term operational stability. Furthermore, this capacitor is resistant to acid and alkaline liquids, making it suitable for application in marine/offshore environments.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on an electrolyte-immersed aluminum foil. It creates an electrical energy storage unit with a large electrical capacity. The device is built with an electrolyte, which stores a large amount of charges, as well as an anode, which is typically made of aluminum foil. A large voltage is used to charge the capacitor, and the current generated from this is led through the electrolyte. The electrolyte then generates ions, which in turn migrate to the anode. The ions neutralize the negative charges, creating a positive charge on the anode.

This capacitor is self-healing and generates a positive pole and negative pole directly, this eliminates the need for additional materials like resistors or the building of multiple capacitors in parallel. As a result, the device can provide the low equivalent series resistor (ESR) that is needed in electrolytic capacitors for high pulsed performances.
