Aluminum - Polymer Capacitors are electronic components that are mainly used in many different applications, such as communications and audio systems. They are often referred to as Aluminum Electrolytic Capacitors due to their construction, and are used for applications that require the highest available capacitance, such as high voltage applications. The PCJ0J122MCL1GS is an aluminum-polymer capacitor that is specifically designed for such high voltage applications. The following will discuss the application field and working principle of the PCJ0J122MCL1GS.

Application Field

The PCJ0J122MCL1GS is a high voltage aluminum-polymer capacitor, designed for use in applications that require capacitance up to 500V DC. Due to its large capacitance, it is often used in high voltage power supplies, DC/DC converters, motor control circuits, motor drives, and other applications where power handling capacity and voltage rating are of high importance. Additionally, it is ideal for applications where high ripple currents are present, as this capacitor is designed to handle such currents.

Working Principle

The PCJ0J122MCL1GS is a type of aluminum-polymer capacitor, which means that it is manufactured by depositing layers of aluminum oxide dielectric and polarizable polymer layers on both sides of a conductive foil. This construction enables the capacitor to have a higher capacitance than the traditional aluminum electrolytic capacitor, since the greater polarization of the polymer allows for a much higher electric field. As a result, the PCJ0J122MCL1GS is able to offer a capacitance of up to 500V DC, and handle very high ripple currents.

The higher capacitance of the PCJ0J122MCL1GS is also due to its combination of water absorption, dehydration and charging effects. In normal mode, water absorption occurs when the dielectric layers absorb water molecules, resulting in an increase in capacitance. Dehydration then occurs when the excess water molecules are driven off the dielectric materials, resulting in a decreased capacitance. And finally, during charging the polymer layers become highly polarized, resulting in an increase in capacitance. This combination of effects allows the PCJ0J122MCL1GS to offer a high capacitance at high voltages.

Conclusion

The PCJ0J122MCL1GS is a high voltage aluminum-polymer capacitor, designed for use in applications that require high capacitance and voltage ratings. Its construction makes it ideal for applications such as high voltage power supplies, DC/DC converters and motor control circuits, where power handling capacity is of high importance. It is able to offer a capacitance of up to 500V DC, and handle very high ripple currents due to its combination of water absorption, dehydration and charging effects. As such, the PCJ0J122MCL1GS is a highly useful tool for applications in the field of aluminum - polymer capacitors.
