Aluminum - Polymer Capacitors: Application Field and Working Principle
Aluminum - Polymer capacitors are a type of electrical capacitors whose capacitance and energy storage capability primarily depends on the construction of aluminum electrodes and a polymer dielectric. They are used in a variety of applications, from general electronic purposes to special-purpose power and voltage conditioning circuits.
Types of Aluminum - Polymer Capacitors
Aluminum - Polymer capacitors come in a variety of configurations, from large, general-purpose devices to tiny surface mount types. The most common types include chip, leaded, and large box-style capacitors. Chip capacitors are available with both polar and non-polar configurations. Leaded capacitors are available in both axial and radial packages and require more mounting space. Large box-style capacitors are typically used for power supplies, signal conditioning, and circuit protection.
Application Areas
Aluminum - Polymer capacitors are widely used in consumer electronics, automotive, industrial, and military/aerospace applications. In consumer electronics, they are commonly found in mobile phones, portable audio players, digital cameras, DVD players, and gaming consoles. They are essential components in various automotive systems, including vehicle immobilisers, car audio, power windows, and power locks. They are also used in avionic systems, military electronics, and sputtering devices for semiconductor manufacture.
Advantages of Aluminum - Polymer Capacitors
Aluminum - Polymer capacitors are prized for their robustness and reliability, enabling the devices to survive in high temperature, shock, and vibration conditions. They deliver low ESR values, with up to 85 percent less than traditional aluminum electrolytic capacitors. These devices also feature smaller package sizes and better capacitance range compared to traditional capacitors. Additionally, they are highly resistant to changes in surge current and have a longer life expectancy.
50PEV33M6.3X8 Application and Working Principle
The 50PEV33M6.3X8 capacitor is a box-style aluminum - polymer capacitor from the 50 series. It measures 6.3mm x 8mm and can handle up to 50 volts. This capacitor is widely used in switches, power supplies, frequencies, and other general electronic applications. This capacitor works by storing electric charge between two metal plates separated by a polymer dielectric. The more charge stored, the higher the capacitance. As the voltage across the plates increases, the capacity of the capacitor also increases.
Conclusion
Aluminum - polymer capacitors are widely used in various applications due to their superior performance, robustness and reliability. The 50PEV33M6.3X8 is a popular box-style capacitor that is used in general electronic applications and is highly reliable in high temperature and shock conditions. It works by storing electric charge between two metal plates and the capacity increases with the voltage across the plates.
