Aluminum Electrolytic Capacitors

35YXH33MEFCT15X11 application field and working principle

Aluminum electrolytic capacitors are widely used in the electronics industry. When 35YXH33MEFCT15X11 is used as a kind of aluminum electrolytic capacitor, it is mainly used to filter and reduce power supply noise, such as eliminating ripple of the switching regulator power supply. What is the principle of action?

The 35YXH33MEFCT15X11 aluminum electrolytic capacitor contains an oxide coating on the aluminum foil electrode and electrolyte. The oxide coating is an insulating layer that separates the positive and negative electrodes of the aluminum foil. When the capacitor is powered, the oxide coating will have a voltage threshold and will form a capacitor after the voltage reaches its threshold.

The 35YXH33MEFCT15X11 aluminum electrolytic capacitor consists of two pieces of aluminum. The positive electrode is an aluminum foil coated with an oxide coating, and the back side is a solid electrolyte material. The negative electrode is an aluminum foil or aluminum triangle. An interface between the oxide coating of the aluminum foil and the electrolyte is formed. When the capacitor is powered, the electric charge is collected on the oxide coated outer surface of the aluminum foil. If the capacitor has a high voltage, the charge will penetrate the oxide coating and form a capacitor.

The 35YXH33MEFCT15X11 aluminum electrolytic capacitor can be used in many application fields. It can be used to increase the capacitance of switching regulators, reduce power supply noise, filter high frequency current in microelectronic circuits and transformers, and to reduce the start-up time of switching regulators. In addition, it can also be used in many signal integrity applications, such as protection circuits, EMI filters, output current limiters, etc.

The working principle of 35YXH33MEFCT15X11 aluminum electrolytic capacitor is largely dependent on the properties of its two electrodes. The aluminum foil with an oxide coating is responsible for the electrical properties of the capacitor. The oxide layer acts as a dielectric layer, creating an insulating barrier between the positive and negative electrodes. This barrier keeps the charges of the two electrodes from mixing together and promotes the absorption of stored electrical energy. The other part is the electrolyte. It is mainly used to moisten the capacitor and provide ions to the electrolyte in order to maintain a stable electrical field.

In summary, the 35YXH33MEFCT15X11 aluminum electrolytic capacitor is widely used in the electronics industry because of its wide range of application fields. Its working principle is based on the properties of the two electrodes, the oxide coating and the electrolyte. It is used to increase capacitance, reduce power supply noise, filter high frequency current and reduce start-up time of switching regulators.
