Aluminum - Polymer Capacitors are a type of capacitor that is composed of two or more alternating layers of an aluminum foil, separator, and a polymer film. Capacitors of this type are very popular amongst circuit designers due to their low profile and excellent performance characteristics, including their ability to withstand short circuit, high ripple currents, and withstand temperatures up to 125°C. The PCF1E220MCL1GS is a surface mount aluminum-polymer capacitor that provides excellent performance characteristics and can be used in many different applications.

Application Field

The PCF1E220MCL1GS aluminum-polymer capacitor is suitable for typical capacitor applications in various areas, including general purpose power supplies and DC/DC converters. It also is suitable for many applications where an ultra-low profile and/or high temperature capability are required. This capacitor is often used in high power audio amplifiers and power supply filtering circuits, as well as special ultra-low-profile applications in medical, automotive, and industrial electronics.

Working Principle

The PCF1E220MCL1GS capacitor is multi-layer construction composed of alternating layers of aluminum foil and a dielectric layer. The aluminum layer is the anode of the capacitor and the dielectric layer is the cathode. When a voltage is applied, the two layers are charged.

The charged layers attract each other, thus creating a capacitance. This capacitance can store a charge, allowing for the electrical current to be maintained for an amount of time. The higher the capacitance, the larger the charge that can be stored and the longer the current will be maintained.

The PCF1E220MCL1GS aluminum-polymer capacitor is designed to provide excellent ferroelectric properties and is highly stable, ensuring both long term reliability and excellent distortion characteristics.

Conclusion

The PCF1E220MCL1GS aluminum-polymer capacitor is a great choice for applications that require a low-profile, high temperature-capable, and highly stable capacitor. It is ideal for use in general purpose power supplies and DC/DC converters, as well as many other applications. It offers excellent performance characteristics and can withstand short circuit, high ripple currents, and temperatures up to 125°C.
