Aluminum - Polymer Capacitors

Aluminum-Polymer capacitors, commonly known as Polymer Electrolytic Capacitors, are one of the most commonly used types of capacitor in the capacitor industry today. A Polymer capacitor is an electrochemical device that stores electrical energy in an electrostatic field and can be used as a filter, charge pump, energy storage device, or output control device.

PCR1A331MCL4GS application field and working principle

Aluminum-Polymer capacitors, such as the PCR1A331MCL4GS, are used for a wide range of applications. Their primary application is in energy storage and stabilization circuits, especially those that require high capacitance, low impedance and high ripple current capabilities. In addition, they are often used in high-voltage, high-frequency, and high-temperature power electronic applications where space is an important constraint. Other uses include noise suppression, power-on reset, and ripple control.

The working principle of the PCR1A331MCL4GS capacitor is based on the electrostatic field formed around a pair of aluminium electrodes and a thin dielectric film of polymer electrolyte. In operation, a voltage applied across the two electrodes creates an electric field that stores electrical energy. This stored energy is then available for use when required. A capacitor can also act as a smooth out sudden changes in voltage, helping to ensure a consistent output.

The PCR1A331MCL4GS is a non-polarized aluminum-polymer capacitor that operates in the voltage range of 3.2 to 4.0 volts. It is a very low-profile, low-profile multi-capacitor designed for use in high-density, high-frequency, and high-temperature power electronic applications. It provides a high capacitance of 330μF, good low ESR of 0.015 Ohms, and high ripple current rating of 4A. It is also RoHS compliant and has an extended temperature range of -55 to +105 degrees Celsius.

The superior features of the PCR1A331MCL4GS capacitor make it an ideal choice for high-frequency applications. In addition, its low profile design helps to save space in tight-fitting applications while its high capacitance and high ripple current rating make it an ideal choice for high-density, high-frequency and high-temperature applications.
