Aluminum electrolytic capacitors are among the most widely used and reliable capacitor types in existence. They are mainly used in high voltage, large capacity applications, and the 35MXR3300M22X25 capacitor is one example of how precisely and effectively this type of component can work. But what makes this particular capacitor unique and how does it work in its intended applications?

What Is the 35MXR3300M22X25 Capacitor?

The 35MXR3300M22X25 capacitor is a long-life general-purpose bipolar electrolytic capacitor. It is a two-part component consisting of a cylindrical aluminum container filled with a solid sulfuric acid electrolyte. It is covered by two polarizing electrodes; the one closest to the aluminum container is referred to as the anode, while the other is the cathode. The 35MXR3300M22X25 is rated for capacitance of 3300 μF with a rated voltage of 35 VDC and an ESR value of 0.90 mΩ.

Application Fields

The 35MXR3300M22X25 capacitor is used in a wide range of consumer electronics and electrical work. It is particularly useful for high-voltage circuits and applications that require high ripple current gains, such as power supply units, audio amplifiers, and low-voltage lighting systems. It is also a popular choice for other high-voltage, high-frequency tasks, such as power supply regulators and AC/DC converters. Due to its long life, it can even be used in intermittent-duty applications, such as in machinery and equipment control.

Working Principle

The working principle behind aluminum electrolytic capacitors is simple but effective. When a voltage is applied to the anode and the cathode, the electrons flow in a triangular pattern between the two electrodes. This is why it is a bipolar component, as current flows in both directions. As the electrons hit the cathode, they form an electric field that stores the energy, while the aluminum container acts as a dielectric to maintain and contain the energy.

The sulfuric acid electrolyte plays an important role in the working of the capacitor, as it helps initiate the chemical reaction between the two electrodes by providing a low resistance path for electrons. This helps to collect more charge and sustain a higher voltage for longer periods of time. In addition, the electrolyte helps to stabilize the capacitor against temperature changes and also serves to prevent electrolysis of the aluminum container.

Conclusion

The 35MXR3300M22X25 capacitor is a reliable long-life bi-polar aluminum electrolytic capacitor. It has a capacitance of 3300 μF with a rated voltage of 35 VDC and an ESR value of 0.90 mΩ. It can be used in a wide range of consumer electronics and electrical work, such as power supplies, audio amplifiers, lighting systems and power supply regulators. Its working principle is simple but effective, relying on an electric field created by the flow of electrons between the anode and cathode, along with a sulfuric acid electrolyte to initiate the chemical reaction and stabilize the capacitor.
