Aluminum Electrolytic Capacitors

Being one of the most commonly used capacitors in electronic circuits, aluminum electrolytic capacitors have a broad application coverage. The B43540C9187M62 is a type of aluminum electrolytic capacitor, which is frequently used in different electronic and digital circuits. Below will be a brief overview of its application field and working principle.

Application Field

The B43540C9187M62 aluminum electrolytic capacitor is a radial-lead capacitor commonly found in consumer electronics. This capacitor is particularly useful for high voltage applications, as the maximum voltage rating reaches 160V. It is usually applied in LED secondary lighting circuits, microphone circuits, TV sets, LCD screens, small electronic instruments, switch circuits, motor running circuits, signal smoothing and power supply circuits, audio amplifiers, audio passive filter circuits, and PCs, among other applciations.

Working Principle

The working principle of aluminum electrolytic capacitors is based on Faraday\'sLaw of Electrolysis. It consists of an anode (positive collector) and a cathode (negative collector) separated by a dielectric medium. The anode is usually made of aluminum foil with a very thin oxide layer on the surface. The cathode is usually made of aluminum ion-neutralized electrolyte. When a voltage is applied to the electrolytic capacitor, positive ions in the electrolyte are attracted to the anode and negative ions in the electrolyte are attracted to the cathode. This creates an electric field with polarization in the dielectric medium, creating a capacitive effect. The anode and cathode then become the two plates of the capacitor, and they store energy between them.

The aluminum electrolytic capacitor does not have infinite capacitance, and the value of capacitance is determined by three factors: the surface area of the two plates, the distance between the two plates, and the permittivity of the dielectric medium. A larger surface area or a shorter distance between the two plates will lead to a greater capacitance. The B43540C9187M62 aluminum electrolytic capacitor has a capacitance of 47uF with a maximum voltage rating of 160V.
