Aluminum Electrolytic Capacitors

The power system is composed of power components as its core components. Various capacitors are also indispensable components. Aluminum electrolytic capacitors are widely used because of their low cost and good performance. The B43540A5826M000 capacitor is one of the most common types of aluminum electrolytic capacitors.

Application Field

The B43540A5826M000 capacitor is mainly used in high-frequency filtering, digital circuit bypass, decoupling power supply and other fields. In general, it is used in the programmable board circuit as a noise filter circuit, which can improve the data transmission or circuit signal processing effect. It is also used in the high frequency signal circuit of frequency modulation receiver, pulse processing circuit, high-speed switch power supply and other products. In addition, it is also used in the power capacitance matching in the wireless communication product, and in the circuit of the inverter power conversion of the motor driving system.

Working Principle

Aluminum electrolytic capacitors are composed of aluminum shell, inner electrolyte and two winding aluminum foils. Its working principle is mainly to master the electric double layer. When the potential difference of the positive and negative poles of the capacitor is higher than the highest potential value of the electrolyte, the electric double layer on the surface of the aluminum film plays a major role in the dielectric of the capacitor. The smaller the equivalent series resistance and the capacitance of aluminum electrolytic capacitors is, the higher their working voltage is. Here, B43540A5826M000 capacitor has a capacitance of 47μF and a rated working voltage of 400V. Furthermore, when the potential difference of the two poles of the capacitor is equal to the highest potential of the electrolyte, the voltage is completely cut off and the capacitor can withstand the voltage well.

When the B43540A5826M000 capacitor is connected in the circuit, it can be connected in series or in parallel according to the actual requirements. When the B43540A5826M000 capacitor is connected in parallel, its capacitance is increased; when the B43540A5826M000 capacitor is connected in series, its effective working voltage is increased. It is worth mentioning that when the B43540A5826M000 capacitor is connected in series, the temperature rise of the capacitor will be increased due to its more internal resistance as compared with the parallel connection.

B43540A5826M000 capacitor is mainly used in the above-mentioned fields. In addition to its low cost and good performance, it also has excellent long-term stability and ripple current capability. In order to ensure its performance, it is necessary to pay attention to its storage and use environment, because the ambient temperature and humidity environment will also have a great impact on the performance of the capacitor.
