Applications of B41252A4279M

This is a non-solid electrolytic capacitor, whose main application is in circuit protection. It is most commonly used to prevent immediate destruction of the device by limiting inrush current during startup. Furthermore, it also helps to protect against in-rush spike current burst or short-circuit current due to high DC voltage while circuit operation. It often appears together with the power supply filter to realize current smoothing and differentiating. In addition, this electrolytic capacitor can also be used in other electronic circuits such as resonant circuit, timing circuit, oscillation circuit, etc.

Working Principle of B41252A4279M

B41252A4279M is a kind of capacitor which is mainly composed of aluminum foil, non-solid electrolyte and metal oxide layer. The anode of this capacitor is aluminum foil, the cathode is metal oxide film on the surface of aluminum foil and the dielectric is mainly electrolyte. Its construction is similar to anode of a battery. When the power supply is connected to it, electric current will be introduced into the capacitor, which generates an electric field, thus, electric charges are stored on the two poles of the aluminum foil. In order to improve the temperature coefficient, the voltage-resistant capacity of metal oxide film on the aluminum foil will constantly increase between 50℃-125℃. Meanwhile, its capacitance will be very low when the temperature is below 0℃ which suits for a better performance at lower temperature. The above process is how an aluminum electrolytic capacitor works.

Conclusion

B41252A4279M aluminum electrolytic capacitor is an important component for circuit protection and power filter circuits in various electronic equipment. The application and working principle of this electrolytic capacitor have been discussed above. With its wide applications and accurate performance, this capacitor has already become one of the most commonly used components in electronics.
