Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are Passive components, used to store electrical energy and release it, providing a capacitor discharge source in addition to periodic rectification of alternating current. Aluminum electrolytic capacitors have wide application fields, such as mobile phone, digital products, electric appliances, instrumentation, automotive electronics, etc. In this article, we focus on the B43501B5227M80 aluminum electrolytic capacitor and explain its application field and working principle.

Application Field of B43501B5227M80

B43501B5227M80 aluminum electrolytic capacitor is a radial conductor. Generally, its rated voltage is 25V and rated capacitance is 220uF. This capacitor has a long lifetime of 2000 hours up to 105°C and can reduce noise by storing electric energy due to its good frequency characteristics. The B43501B5227M80 aluminum electrolytic capacitor is mainly used in switching power supply, LCD monitor, server, and charger for mobile phone device.

Working Principle of B43501B5227M80

Aluminum electrolytic capacitor is composed of three parts, shell, core and electrodes. The shell used for B43501B5227M80 aluminum electrolytic capacitor is generally made of plastics and linear material can be of safety class UL94/V-0 with polished coating and leadwire type. The core is composed of an anode and a cathode, and the electrodes are made of aluminum foil. In the process of working, the anode is connected to the alternating current while the cathode is connected to the ground. When the alternating current passes through the electrodes, it causes an electric field of reverse direction in the electrolyte. Under this electric field, the aluminum barrier layer on the surface of the anode melts, and it absorbs a large amount of positive ions in the electrolytic solution, forming a polarized component with a capacitance, whose argument polarity corresponds to the electric field direction.

Conclusion

It is widely used in building blocks of electronic products, such as phones, PCs, LCD monitors etc. The B43501B5227M80 aluminum electrolytic capacitor has a long lifetime of 2000 hours up to 105°C, and it can store the energy of the power, reducing noise. Its working principle is relatively straightforward, both anodes and cathodes are connected to respective circuits and when the alternating current passes, electric filed with reversed direction is created, thus forming a polarized component with capacitance.
