Aluminum electrolytic capacitors are widely used in fields such as energy conversion, electronic equipment, lighting, aerospace, instrumentation and medical, and are an important part of electrical products. Among them, B41889A3108M8 aluminum electrolytic capacitors have a wide range of application fields and working principles.

Application fields

B41889A3108M8 aluminum electrolytic capacitors have a wide range of application fields. When used in energy conversion systems, it provides a filtering circuit for pulsed scan systems to suppress interference. In electronic equipment, it can provide a decoupling circuit to provide stable and reliable power supply for each circuit. It is also used in the lighting system to filter the driving voltage of the light source driver, in the aerospace system as an oscillation circuit to amplify the weak signal to make it stable. In the instrumentation and medical systems, it can be used as a resonance circuit to filter and stabilize the signal.

Working principle

The working principle of the B41889A3108M8 aluminum electrolytic capacitor is to take advantage of the electrolysis in the electrolytic solution as the dielectric medium of the capacitor, that is, the dielectric constant is very large. Because the dielectric medium of the electrolytic capacitor is not insulator, but electrolyte, the specific capacitance of the capacitor is very large, so it is one of the capacitors with high capacitance. The capacitor is made of aluminum foil for the positive pole and paper wax for the negative pole. Its structure is pressed in a can-shaped vessel. This structure forms a very reliable electric double layer capacitor.

For B41889A3108M8 aluminum electrolytic capacitors, when the applied voltage is positive, the polarization role is generated, and the oxide film on the surface of the anode aluminum foil is thickened, and the dielectric constant is increased. When the reverse voltage is applied, the oxide film on the surface of the anode aluminum foil is reduced. When the oxide film is reduced, the breakdown electric field strength of the oxide film is reduced, the dielectric constant is reduced and the phenomenon of leakage current appears. Under normal operating conditions, leakage current is too large, it will cause the capacitor to overheat or short circuit.

Conclusion

B41889A3108M8 aluminum electrolytic capacitors are widely used in energy conversion, electronic equipment, lighting, aerospace, instrumentation and medical applications. It takes advantage of the electrolysis in the electrolytic solution as the dielectric medium, and can provide stable and reliable power supply for the driving voltage of light source drivers, amplify the weak signal to make the signal stable, and filter and stabilize the signal. It has the characteristics of high capacitance, but needs to pay attention to the phenomenon of leakage current when used.
