Aluminum electrolytic capacitors are electronic components made of aluminum oxide, which are used for energy storage in an electronic circuit. They are one of the most commonly used types of capacitors and are commonly used in many electronic systems. The model 25YXM100MEFC6.3X11 is a type of aluminum electrolytic capacitors.

Application field and Working Principle

Aluminum electrolytic capacitors are capacitors that use a physical phenomenon of changing the electrolyte in the capacitor to control the electric energy stored in the capacitor. The 25YXM100MEFC6.3X11 is designed for applications operating in temperature range of - 40°C to + 105°C and features five different capacitance options ranging from 25 to 100 µF. It is used for applications such as power supplies, motor starters, charger circuits, motor control and medical equipment. With its capacitor voltage of 450V, this model is also suitable for lighting applications.

Aluminum electrolytic capacitors have a basic construction, consisting of a thin aluminum foil or a double-layer laminated plate that serves as one plate of the capacitor, and an electrolyte as the other plate. The electrode surface of the aluminum foil is covered with a thin layer of aluminum oxide. This oxide layer forms a major part of the dielectric film within the capacitor, creating the ideal condition for energy storage. The electrolyte is then poured over the aluminum oxide-covered aluminum foil layer, forming a connection between the two layers. This arrangement is held in place by crimping the edges of the aluminum plate and the end plate together.

The capacitance of the variable electrolyte capacitor is determined by the amount and type of electrolyte used. As the amount of electrolyte increases, the capacitance increases. Equally, the type of electrolyte used will also affect the capacitance of the capacitor. For aluminum electrolytic capacitors, organic electrolytes such as ethylene glycol are often used, as they provide good electrical properties when compared to other electrolyte types.

Aluminum electrolytic capacitors also feature an oxide barrier at the bottom of the capacitor. This barrier acts as an insulating layer for the electrolyte, thus preventing any leakage between the capacitor plates. The oxide barrier also prevents any excess charge from diffusing out of the capacitor, helping to increase the overall efficiency of the capacitor. The oxide barrier of the 25YXM100MEFC6.3X11 is said to be able to handle up to 2000 hours at a maximum frequency of 1000Hz.

The 25YXM100MEFC6.3X11 can be used in various applications due to its high capacity and long lifetime. In particular, it is suitable for switching power supplies, lighting, AC adapters, and other power related applications. In addition, its high ripple current rating, high voltage endurance, low dissipation factor, and long life are some of the factors that make it an attractive choice for many applications.
