Aluminum Electrolytic Capacitors

250CFX15M10X20 Application Field and Working Principle

Aluminum electrolytic capacitors are a type of capacitors that use aluminum foil as the anode and a thin insulating alumina layer as the cathode. The oxide layer of the anode acts as the dielectric and a liquid electrolyte acts as one of the electrodes. Due to the large dielectric constant and higher conductivity than other types of capacitors, aluminum electrolytic capacitors have a higher capacitance for a given size. However, aluminum electrolytic capacitors also have lower maximum capacitance and shorter lifetime than other capacitor types.

The 250CFX15M10X20 aluminum electrolytic capacitor is a radial leaded electrolytic capacitor with an 85°C maximum operating temperature. The maximum capacitance is 15uF, the rated voltage is 10V, and the tolerance is ±20%. The casing is made from epoxy resin and measures 10mm x 20mm.

The primary application field of the 250CFX15M10X20 aluminum electrolytic capacitor is filtering and energy storage. It is commonly used in power supplies, especially those that operate at higher frequencies, as they can provide long-term stability and consistent filtering performance. The capacitor can also be used in audio circuits, such as high-end amplifiers, as well as motor control applications.

The working principle of the 250CFX15M10X20 aluminum electrolytic capacitor is based on Faraday’s law of electrolysis. When a voltage is applied to the two leads of the capacitor, current flows between them and electrochemical reactions take place at both the anode and cathode. The resulting ions form a thin electrically-conducting layer on the electrode surfaces, and this in turn creates an electric field across the capacitor’s plates. The electric field creates an electric potential across the plates that is equal to the potential difference between the two leads. The capacitance of the capacitor is proportional to the area of the plates and inversely proportional to the distance between them.

In summary, the 250CFX15M10X20 aluminum electrolytic capacitor is a radial leaded electrolytic capacitor with a maximum capacitance of 15uF and a rated voltage of 10V. It is primarily used for filtering and energy storage applications, such as in power supplies and motor control circuits. The capacitor works on the principle of Faraday’s law of electrolysis, where an electric field is created across its plates when a voltage is applied. This creates an electric potential across the plates that is equal to the potential difference between the two leads.
