Aluminum - Polymer Capacitors

Aluminum - Polymer capacitors are capacitors produced using an anode in an aluminum electrolytic. They are manufactured by constructing conductive polymer elements on an aluminum substrate and an anode as the second electrode in an electrolyte. The latter is either a solid polymer film or a liquid (a gel). These capacitors have a dielectric with a much higher capacitance than that of aluminum electrolytic capacitors.

The specifics of the PCV1E121MCL1GS capacitor provide the unique application field and working principle. The PCV1E121MCL1GS capacitor is a surface-mount, aluminum-polymer, E-Series capacitor. The E-Series of aluminum-polymer capacitors provide large capacitance in a form factor that features a high-temperature (105°C) rating and extended life performance. This device is lead-free and RoHS compliant as well as halogen free.

Specifically, the E12-series capacitors from Panasonic are designed to offer best-in-class lifetime performance. The product uses patented PAN VS Technology with an advanced nanocomposite dielectric material, which is formed through a special manufacturing process and what\'s more, it has electrochemically formed aluminum foils with a characteristic of lower ESR values. This leads to to improved performance, reliability and extended lifetime.

These capacitors have a working voltage of 16V and capacitors values ranging from 10 μF to 1000 μF. Their small size, highly stable construction, and ease of use make them suitable for a variety of applications such as automotive, audio, medical, military, and power electronics applications.

The working principle of aluminum-polymer capacitors is based on the principle of an electrolytic capacitor, with an electrolyte (gel or polymer) as the dielectric medium. The capacitor has an anode and a metalized electrodes embedded in the dielectric. The anode is placed in direct contact with the metalized electrodes, and when the unit is energized, ions are generated and move the metalized electrode to the anode. The positive and negative ionic charge on the metalized electrodes creates a capacitive effect.

As the electric current passes through the capacitor, electrons are transferred from the metalized electrodes to the anode, and from the anode to the metalized electrodes. The quantity of these electrons transferred is dependent on the applied voltage. The total capacitance value of aluminum-polymer capacitors is determined by the sum of the individual capacitance values of the metalized electrodes, since each metalized electrode contributes to the capacitance.

In terms of its application field, the PCV1E121MCL1GS capacitor are used most commonly in dc-to-dc power converters, power supplies, filter circuits, and audio electronics. They are also well-suited for automotive, audio, medical, military, and industrial applications due to their low ESR, extended life performance, and high-temperature rating. Additionally, they are well-suited for applications where size and weight are key factors.

In conclusion, the aluminum-polymer capacitor PCV1E121MCL1GS enjoys a high working voltage, low-ESR characteristics, and extended life performance. It is a lead-free and RoHS compliant, halogen-free, and offers excellent size and weight advantages to a variety of applications. Its unique application field and working principle make it one of the most versatile and widely used components in the industry.
