Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors, as the name suggests, are polarized capacitors that uses a thin semiconductor oxide layer as the dielectric and an electrolyte solution to form a conductive media. They are composed of two aluminum foil electrodes. The anode has a much larger area than the cathode foil and is perforated to produce an increased surface area. This increases the capacitance of the device.

The 35YK470M10X16 is an aluminum electrolytic capacitor that is rated at 10 volts and has a capacitance of 470μF. It is usually used in applications that require high reliability such as power supplies, surge protection circuits, LED drivers, and hearing aids. It can also be used in various automotive applications such as window washer pumps, fuel pumps, alternators, and starter motors.

Application Field and Working Principle

The applications for the 35YK470M10X16 capacitor are mainly in power supply and dc-to-dc conversion applications, including voltage regulators, switching power supplies, and pulse width modulation circuits. It is also suitable for motor speed control circuits and power factor correction circuits. This capacitor is also often used in audio applications as a high-frequency bypass capacitor.

The working principle of the aluminum electrolytic capacitor is based on electrochemistry. When a voltage is applied across the capacitor component, the oxide layer of the anode is converted to alumina, which is an ionically conducting form of aluminum oxide. This allows the electric charge to flow through the capacitor, establishing a current. As the electric current flows through the device, electric charges are built up on each side from the current.

When the voltage is removed, the alumina tends to redissolve back into the electrolyte and the electric charge on both sides of the capacitor dissipates. As the current is reduced, the capacitance of the device decreases. As the electric charge is removed, the oxide layers of the electrodes are restored, resulting in a decrease in capacitance until the device reaches its equilibrium state.

The 35YK470M10X16 aluminum electrolytic capacitor offers high reliability and performance, making it suitable for use in many different applications. Its construction is simple and cost-effective, making it an ideal choice for many application areas.
