106SVF025M

Construction

The 106SVF025M is composed of a high-purity aluminum foil etched with many fine parallel lines that form the capacitor plates, a paper or a plastic film that serves as the separator, and an electrolyte of aqueous boric acid containing a dissolved aluminum salt such as aluminum sulfate. This electrolyte forms a thin film of aluminum oxide on the surfaces of the aluminum foils. The aluminum oxide acts as the dielectric, while the aluminum foil acts as the plates of the capacitor.

Application Field

Due to their high capacitance-voltage ratio, long life, and excellent electrical performance, the 106SVF025M is widely used in a variety of applications in the electronics industry. Some of the most prominent applications include:

• Power supplies
• Audio applications
• Power converters
• High-current filtering
• Switching circuits
• TVs, radios, and other home electronics
• Medical equipment

Working Principle

The working principle of the 106SVF025M is based on two effects: capacitance and electrolysis. Capacitance is a function of the area and spacing between the capacitor\'s plates. When a voltage is applied between the plates, the electric field in the dielectric creates an electric double layer in the plate-separator interface. This causes a charge displacement, creating a current that is characteristic of a capacitor. Additionally, the electrolyte in the 106SVF025M provides electrolysis, which increases the effective capacitance.

Advantages of the 106SVF025M

The 106SVF025M offers several advantages when compared to other aluminum electrolytic capacitors. These advantages include:

• High reliability
• High capacitance-voltage ratio
• Low leakage current
