Aluminum electrolytic capacitor products, such as 400BXC6.8MEFC10X12.5, are a type of capacitor used in many hybrid electronic systems and printed circuit boards. Such capacitors generally have an anode of aluminum foil, a dielectric of alumina oxide, and an internal electrolyte of liquid or gel. Despite their limited capacitance they are still widely used, due to the fact that they offer high capacitance and good ESL and ESR values in a package that is small enough for many applications.

Application Field of 400BXC6.8MEFC10X12.5

The 400BXC6.8MEFC10X12.5 is an example of a non-polarized aluminum electrolytic capacitor, which means that it does not have a positive or negative lead. This type of capacitor is used in many DC applications, such as blocking and decoupling circuits, power factor correction, and filtering and buffering circuits. It is also well suited for coupling, bypass, and timing circuits, as well as in the supply lines of linear and switched power supplies.

Working Principle

The working principle of an aluminum electrolytic capacitor like the 400BXC6.8MEFC10X12.5 is based on Faraday’s law of electrochemistry. When a voltage is applied to the leads, the dielectric material between the anode and cathode (in this case, alumina oxide) is effectively pulled apart, creating a dielectric layer. This layer enables the formation of a local space-charge, which is similar to an electric field. This space-charge is what stores energy in the aluminum electrolytic capacitor. The thickness of the dielectric layer is dictated by the applied voltage, as well as the capacitance and voltage rating of the capacitor.

When the voltage is removed, the dielectric layer dissipates, and the capacitor no longer retains energy. This process is why aluminum electrolytic capacitors are generally used for short-term or transient uses, as they have limited capacitance, as well as a limited temperature range.

Conclusion

The 400BXC6.8MEFC10X12.5 is an example of a non-polarized aluminum electrolytic capacitor, which is used in many DC applications, such as blocking and decoupling circuits, power factor correction, and filtering and buffering circuits. The working principle of an aluminum electrolytic capacitor is based on Faraday’s law of electrochemistry, and the capacitor stores energy in the form of a space-charge. This space-charge is dictated by the applied voltage, as well as the capacitance and voltage ratings of the capacitor.
