Aluminum-Polymer Capacitors

Aluminum-polymer capacitors are a type of electronic component that is used in numerous applications. They are often referred to as “supercapacitors” because of their high energy density and capacity, which far exceeds that of conventional electrolytic capacitors. As opposed to electrolytic capacitors, which use electrolyte as the dielectric material, aluminum-polymer capacitors use a special dielectric material known as a “dielectric polymer”. This allow them to offer a variety of advantages, including higher capacitance, higher temperature range and a longer life expectancy.

SPA820M04B Application Field and Working Principle

The SPA820M04B is an aluminum-polymer capacitor that is used for many different applications. It is a very small capacitor (4.3mm x 3.3mm) that is capable of handling a maximum voltage of 4V. This makes it ideal for applications where space is of the essence, such as in mobile phones, digital cameras and other portable electronic devices. It is also a very stable and reliable capacitor that is resistant to damage from both shock and vibration.

The SPA820M04B works by using a special dielectric material known as a “dielectric polymer”. This material is sandwiched between two metallic electrodes, one of which is made of aluminum. The dielectric material serves as an insulator, allowing electrons to be stored and released on demand. This allows for a rapid transfer of energy when used in an electrical circuit.

The SPA820M04B is often used in power supplies, DC-DC converters, automotive systems and many other applications. Due to its high energy density, it can handle high power pulses, making it an ideal choice for applications that require instantaneous peak power. It is also very reliable and can provide stable and consistent performance over long periods of time.

In addition, the SPA820M04B is also resistant to temperature changes, meaning that it can handle operations in both high and low temperature environments. This is another advantage of these capacitors, as they are capable of operating in the harsher environmental conditions that other types of capacitors cannot. This makes them ideal for applications in extreme weather conditions, including aerospace and military applications.

The SPA820M04B is also a very cost-effective capacitor, as it is capable of providing a large amount of capacitance for less money than other types of capacitors. It also has a very long life expectancy, which further adds to its cost effectiveness.

Overall, the SPA820M04B is a very reliable and durable aluminum-polymer capacitor that is suitable for numerous applications. It is very small in size, yet packs a powerful punch of energy and can handle a variety of conditions. This makes it an excellent choice for applications where space and cost are of the essence.
