Aluminum - Polymer Capacitors

Aluminum - polymer capacitors, also known as “supercaps”, are energy storage devices capable of storing energy and releasing it quickly. In contrast to traditional capacitors, they are made with a mixture of carbon and aluminum foil, with a conductive polymer electrolyte, instead of an electrolytic solution and separator. The popular PCG1C471MCL1GS is one such aluminum - polymer capacitor, used in a wide range of applications from industrial applications to consumer electronics. It is especially usefulin situations where the required voltage is between 2.7 and 5.5 volts. The advantage of this type of capacitor lies in the fact that it can provide a short duration high-power charge and discharge application. This allows for a variety of uses, such as smoothing voltage fluctuations, providing starting torque for stepping motors, and energy conservation.

Application Field

The PCG1C471MCL1GS provides a versatile and reliable energy source when integrated into a variety of circuits and applications. It has been widely used in automotive electronics, camera stabilization systems, UPS, LED lighting systems, and point-of-load converters (POL). This capacitor is also beneficial for managing high inrush current, low on-time, and battery-less operation in portable applications such as wearables and IoT devices.In addition, the PCG1C471MCL1GS is frequently used in various industrial applications. It’s abilities to deliver high power in short-duration pulses make it ideal for applications such as motor starting, welding, drilling, and PLC pulsing circuits. Furthermore, it can be used as a power-hold/buzzer driver for modems and motherboard systems, and as a backup power supply for memory devices.

Working Principle

Aluminum - polymer capacitors operate similarly to traditional electrolytic capacitors. However, instead of relying on a liquid electrolyte, they use a semi-solid electrolyte of conductive polymer, usually dissolved into an organic solvent. This type of capacitor uses aluminum foil as the anode and a special polymer film as the cathode. Upon the application of a voltage, ions of the electrolyte move into the spaces between the aluminum foil and polymer film. This forms a double layer of ions, both positive and negative, which hold a charge and store energy.When the voltage is removed, the charge is maintained due to the balanced electrochemical reaction between the electrolyte and the electrodes. For example, when a current is supplied to the PCG1C471MCL1GS, electrons flow through the electrolyte enabling energy to be stored. When the current is removed, the electrons remain stored in the electrolyte. This allows for a quick discharge of the capacitor when necessary.Overall, aluminum - polymer capacitors are highly efficient, reliable, and durable components. The PCG1C471MCL1GS provides robust, compact, and lightweight energy storage for a variety of industrial, automotive, and consumer applications. With their ability to supply short duration high-power bursts, these capacitors are ideal for a variety of applications ranging from automotive electronics to industrial welding circuits.
