Aluminum - Polymer Capacitors
Aluminum - polymer capacitors (20SEP22M) are a type of capacitor constructed from a combination of aluminum and a polymer material. Unlike other types of capacitors, such as aluminum electrolytic or paper capacitors, their temperature range and stability properties are greatly increased. This is due to the combination of higher capacitance-voltage performance, improved temperature stability and the ability to use the polymer as a dielectric.
Application Field
The combination of aluminum and polymer materials, along with their increased temperature range and stability properties make 20SEP22Mcapacitors especially attractive for use in a variety of applications. One such application is high power circuits where excess energy is absorbed and dissipated quickly to prevent damage to other components. They are also used for suppressing high power transient spikes in power supplies, low power switching devices and charge pumps, and input capacitors in switching power supplies. Other potential application areas include optical communication devices, power converters and DC-DC convertors.
Working Principle
The operational principle of aluminum-polymer capacitors is based on a combination of conduction and insulation. This combination enables the capacitors to maintain a higher capacitance (measured in F) than would otherwise be possible. The polymer dielectric material, which can often be chosen to be thermally and chemically stable, is sandwiched in between two electrodes. The voltage is applied across the electrodes and the current flows through the capacitor. The polymer absorbs the electrical energy and releases it when the power is disconnected, maintaining a stable and high capacitance.
Benefits
The combination of aluminum and polymer materials used in the construction of 20SEP22M capacitors provides a number of advantages over other types of capacitors. They can maintain a high capacitance over a wide temperature range and are also very resistant to voltage and current surges. In addition, they are much more reliable than other types of capacitors, such as aluminum electrolytic capacitors, due to the stability of their dielectric material. They also have low ESR (equivalent series resistance), enabling them to absorb and dissipate the energy quickly and efficiently.
Conclusion
Aluminum-polymer capacitors are a highly efficient and reliable capacitor suitable for a wide range of applications. 20SEP22M capacitors are especially attractive due to their increased temperature range and stability properties, making them well suited for high power circuits, low power switching devices and charge pumps, and input capacitors in switching power supplies. The combination of their aluminum and polymer technologies provide an outstanding performance with limited sizes, making them an ideal choice for a range of electronic applications.
