Working Principle

The B43511B9108M87 aluminum electrolytic capacitor consists of an anode, a cathode, and an electrolyte. The anode is an aluminum foil with an oxide film on its surface, which is the main dielectric of the device. The cathode is a conductive polymer film or wire, which is also the main electrode (current collector) of the device. The electrolyte is a liquid or gel that bridges the two electrodes and electrolytically forms an oxide layer on the anode, thus creating a capacitive effect. The anode oxide layer is the dielectric of the capacitor and provides a barrier between the positive and negative charges stored in the anode and cathode, allowing the capacitor to store energy.

The B43511B9108M87 aluminum electrolytic capacitors have a number of advantages over conventional capacitors. They have high capacitance and withstand high ripple currents. They maintain a constant capacitance over a wide temperature range and withstand high voltages. Finally, they are small and light in weight, making them ideal for many compact applications.

In conclusion, the B43511B9108M87 is an aluminum electrolytic capacitor with high capacitance and a small form factor. It is suitable for use in a wide range of applications, including power and energy storage, filtering, power supply smoothing, DC/DC converter applications, and keyboard decoupling. The working principle of the device is based on the formation of an oxide layer on the anode, which serves as the capacitor’s dielectric. The B43511B9108M87 is a reliable and cost-effective choice for many applications.
