Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most commonly used electronic components used to store electric energy in the form of electrostatic charge. They are usually divided into two categories: polarized aluminum electrolytic capacitors and non-polarized aluminum electrolytic capacitors. Generally, the former refers to capacitors with an anode, a cathode and a diaphragm, while the latter refer to capacitors without a diaphragm. The most common type of aluminum electrolytic capacitor is a non-polarized capacitor with a cylindrical body.

10YXF100MEF-CT15X11 Application Field and Working Principle

The 10YXF100MEF-CT15X11 is a radial aluminum electrolytic capacitor, which is a kind of non-polarized aluminum electrolytic capacitor. It is a cylindrical-shaped capacitor with an outer layer of an aluminum hydrogen containing cathode material. Its rated temperature range is -55℃ to +105℃, and its typical capacitance value is 100uF with a Value Maximum of +20%.

This aluminum electrolytic capacitor has wide application fields, such as audio equipment, LED dimming, energy management systems, automotive electronics, computer motherboards and many other electronic circuits needing energy storage or energy filtering.

The working principle of the 10YXF100MEF-CT15X11 aluminum electrolytic capacitor can be illustrated as follows: when a positive temperature coefficient is applied to the anode, the conducting oxide film which is formed on the anode by aluminum vaporization will be separated from the anode. This phenomenon allows electrons to flow from the anode to the cathode, resulting in an electric charge transferred from the anode to the cathode and thus a capacitance is generated. When the applied electric signal is removed, the anode will restore its conducting oxide film and the electrons will flow back to the anode resulting in the discharging of the capacitance.

Advantages and Disadvantages

The 10YXF100MEF-CT15X11 aluminum electrolytic capacitor has several advantages over other types of capacitors, primarily due to its ability to both store and release electrical energy quickly. It also has high charge density, high capacity, long life and temperature and weather resistance. Additionally, this aluminum electrolytic capacitor is relatively low cost, making it an ideal choice for a variety of applications.

However, this aluminum electrolytic capacitor has one major disadvantage, which is its relatively large internal leakage, compared to other types of capacitors. This means that the capacitor needs to be frequently replaced, given its short life. In addition, this capacitor is quite sensitive to temperature and humidity, and it tends to be prone to corrosion. Therefore, this capacitor is not suitable for applications in high moisture environment, or in applications requiring long-term storage or rolling data.

Conclusion

The 10YXF100MEF-CT15X11 aluminum electrolytic capacitor is a reliable and cost-effective option for various electronic circuits requiring energy storage or energy filtering. Its advantages such as high charge density, high capacity and long life are particularly suited for use in audio equipment, LED dimming, energy management systems and automotive electronics. However, its main disadvantage is its relatively large internal leakage which leads to a short lifespan, making frequent replacement necessary. It is also relatively affected by temperature and humidity and is therefore not suitable for applications in high moisture environments or for applications requiring long-term storage or rolling data.
