8SW68M Capacitors

Aluminum - Polymer Capacitors

Aluminum - polymer capacitors, also known as aluminum-polymer electrolytic capacitors, are a type of electrochemical capacitor that utilizes a solid dielectric electrolytic polymer to bridge the gap between the plates. This type of capacitor offers a number of advantages over other types of capacitors, including high capacitance density, low ESR, and higher temperature stability. Although they are more expensive than other types of capacitors, they are often used in demanding applications where their features are needed.

8SW68M Application Field and Working Principle

The 8SW68M aluminum-polymer capacitor is a standard MLCC (multi-layer ceramic capacitor). These capacitors are most commonly used for bypass, filtering, and decoupling functions in a wide range of electronic applications. The 8SW68M is a small, 180V capacitor that has a capacitance of 220μf. It offers a relatively high capacitance density and is able to operate in temperatures up to 105°C.

The 8SW68M consists of an anode composed of two aluminum plates, a solid dielectric electrolytic polymer as the electrolyte, and a cathode composed of a nickel-plated steel plate. When voltage is applied, an electric field is created across the anode and cathode plates which causes the electrolyte to become ionized. This causes ions to move between the plates, creating an electric current. This current creates an electrostatic field between the plates, which is the basis of the capacitor\'s operation.

The 8SW68M also utilizes a unique design to enhance its performance. It is made up of multiple parallel-connected layers of polymer electrolyte, which allow for better uniform current distribution and greater energy storage capacity. Additionally, its design features a stainless steel plate that acts as a back plate to help prevent electrochemical corrosion of the aluminum plates.

Conclusion

The 8SW68M aluminum -polymer capacitor offers a number of advantages that make it well suited for a wide range of electronic applications. Its high capacitance density, low ESR, and temperature stability make it a viable choice for many demanding applications. Additionally, its unique design helps to further enhance its performance and ensure enhanced reliability.
