Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most common type of general purpose capacitors available on the market. They offer a wide range of characteristics to meet a variety of applications and are used in almost all types of electronic products.

The B43501A3157M67 is an excellent example of an aluminum electrolytic capacitor. It is a radial leaded capacitors with axial leads providing excellent vibration-resistant for high-reliability applications. It has a capacitance of 15uF, a DC working voltage of 50V, and a temperature coefficient of -40/+85ppm/K. The capacitance is high, so it is ideal for power-supply smoothing, AC mains filtering, switching-power-supply input/output filters, and other DC filtering applications.

In terms of working principle, an aluminum electrolytic capacitor consists of an anode and a cathode. The device is manufactured by rolling aluminum foil for the anode and separating the two with an electrolyte material known as the dielectric. When the capacitor is connected to a DC voltage source, current passes from the anode to the cathode and forms an electric charge. The aluminum foil anode will become polarized and attracted to the negative terminal, while the dielectric acts as the insulation between the two plates. As current continues to flow, more charge is built up on each of the plates.

In terms of application fields, aluminum electrolytic capacitors are widely used in motor related applications and power supplies. They are also used for high current smoothing filters, AC mains line filtering, and for motor start capacitors. Furthermore, they can also be used to decouple or bypass RF signals to reduce overly fast rise times of the signals.

The B43501A3157M67 is a great aluminum electrolytic capacitor for high-reliability applications, with excellent vibration resistance. With its 15uF capacitance and DC working voltage of 50V, it is suitable for power-supply smoothing, AC mains filtering, switching-power-supply input/output filters, and other DC filtering applications. Furthermore, it works on the principle of a polarized electric charge stored between two plates with a dielectric material separating them.
