Aluminum - Polymer Capacitors, a type of electronic components which combine the strengths of aluminum electrolytic capacitors and conductive polymer electrolytic capacitors, are widely used in many devices and applications. This article will focus on PCX1E181MCL1GS, a general purpose aluminum - polymer capacitor, and its application fields and working principles.

PCX1E181MCL1GS is a general purpose aluminum-polymer capacitor which can be used in many applications and devices including cell phone, laptop, and IoT devices because of its small sizes, low ESR, and high reliability. It has multiple features of aluminum electrolytic capacitors including high volumetric efficiency and good energy storage capability, while having features of conductive polymer electrolytic capacitors such as low conductive resistance, long operating life and price which is slightly lower than aluminum electrolytic capacitors. Thus its applications field includes half-bridge converters, LLC converters, DC-DC step-down converters and other wide-range DC-DC down convertors etc.

Now let’s talk about the working principle of PCX1E181MCL1GS. The working principle is actually quite simple. It is based on the basic convention of a capacitor which is electrostatic shielding. The positive and negative electrodes of the capacitor are separated by a dielectric medium which is usually made of aluminum foil and conductive polymer. This dielectric medium forms an electric field which creates a shield that blocks the flow of electric current. As the voltage of the circuit increases, the electric field gets stronger and blocks the electric current more effectively. The aluminum-polymer capacitor uses this same principle to control and limit electric current in a circuit.

Since PCX1E181MCL1GS combines the features of both aluminum electrolytic capacitors and conductive polymer electrolytic capacitors, it offers many advantages including low cost, high volumetric efficiency, long operating life and excellent energy storage capability. It is suitable for use in many applications such as half-bridge converters, LLC converters, DC-DC step-down converters and wide-range DC-DC down convertors requiring high reliability and miniature size. Thanks to its many advantages, quickly growing popularity of the aluminum-polymer capacitors are ever increasing in many devices and applications.
