B43041A9106M

Application Field

Aluminum electrolytic capacitors are normally used in power supplies, AC/DC converters, convertors and many other applications as snubbers, coupling, noise filtering, and pulse shaping.The B43041A9106M models are widely used in AC/DC adaptors for noise-free and stable power supply. It is constructed with a high-grade aluminum core sealed with a double-anodized aluminum shell structure and constructed with two pieces of cylindrical aluminum containers that are filled with electrolyte.The B43041A9106M series are especially suitable for use in high temperature applications such as LCD displays. Their temperature range ratings goes from -40°C up to 125°C making these capacitors suitable for operations in harsh environments.

Working Principle

Aluminum electrolytic capacitors are composed of two aluminum foils that are insulated from each other with a thin layer of oxide film. This oxide film acts as a dielectric and hence the name “electrolytic” capacitor. One of the aluminum foils is etched and made into anodes and the other foil is connected to ground. The electrolytic capacitor’s working principle is based on the Faraday Principle, which says that when an electrical current flows through an electrolytic solution, it will cause chemical reactions that will deposit the ions onto the electrodes forming a layer of dielectric. This in turn creates a capacitance on the device.

However, as compared to traditional capacitors, the electrolytic capacitors are low-valued and high-ripple current. This is due to the process of manufacturing which causes corrosion on the wire surfaces. The B43041A9106M is designed with large capacitance and an ultra-low equivalent series resistance (ESR) of 20mΩ making them suitable for power-supply applications such as adaptors, which require large current flows.

Conclusion

The B43041A9106M aluminum electrolytic capacitor is a popular, high-grade device suitable for applications with high temperatures and large current flows. Its large capacitance and low-ESR enable it to be used in power supplies, AC/DC converters, and many other applications. The working principle of the B43041A9106M is explained through the Faraday Principle and involves a dielectric layer being formed by the chemical reaction between the electrolytic solution and the anode.
