Aluminum-polymer capacitors are capacitors with a composite structure of an aluminum foil coated with an ionic or polymeric film, a separator placed between two plates and the electrolyte, and electrodes contacting the electrolyte and the backing foil. The PCX1E220MCL1GS is an aluminum-polymer capacitor that is part of the Infinity Cap line of capacitors and is distinguished for its advanced formulation and low leakage current capabilities.

Application Field

The PCX1E220MCL1GS aluminum-polymer capacitor is ideal for applications such as LED lighting, LED backlights, inverters, automotive, power conversion, and power supplies. Its high capacitance, low equivalent series resistance (ESR), and ultra-low leakage current are features that make it a suitable choice for high-current applications where space constraints limit other types of capacitors.

Working Principle

The PCX1E220MCL1GS works based on the application of electrical charge on two conductive plates located between two separators or a dielectric. This charge induces current flowing between the two plates, creating an electric field that stores energy. When a voltage is applied across the capacitor, a current will flow, which will result in a capacitive reactance that depends on the capacitance of the capacitor, the frequency of the voltage, and the distributed capacitive effects due to its electrical construction.

The PCX1E220MCL1GS aluminum-polymer capacitor features a special self-healing dielectric material that combines aluminum and polymers, providing high capacitance, low ESR and ultralow leakage current. This special combination of materials yields a reliable, high-performance capacitor that can provide exceptional performance in applications over a wide temperature range. The capacitor also exhibits superior vibration and shock-proof qualities, making it an ideal choice for applications requiring long life and reliability.

The PCX1E220MCL1GS is also a polar device, meaning it must be installed in the proper orientation to ensure proper operation. The capacitor is rated for operation from -55°C to +125°C, making it suitable for a wide range of applications. The PCX1E220MCL1GS also has a wide operating range of -40Vdc to +40Vdc.

In summary, the PCX1E220MCL1GS is an aluminum-polymer capacitor that is part of the Infinity Cap line of capacitors, distinguished by its special self-healing dielectric, high capacitance, low ESR, and ultralow leakage current. It is suitable for many applications, including LED lighting, LED backlights, inverters, automotive, power conversion and power supplies, and is rated for operation over a wide temperature range, with a wide operating range.
