Aluminum electrolytic capacitors are polarized electrochemical capacitors that contain an electrolyte composed of organic solvents, such as ethanol, propylene glycol, and glycerin, in order to form an oxide film on an aluminum foil. This film is an insulating layer that allows a charge to be stored on the opposing plates of the capacitor. The MALREKA00PB347DL0K is an example of such a device.
The MALEREKA00PB347DL0K is an aluminum electrolytic capacitor with a rated voltage of 450 volts DC and capacitance of 4.7 µF. It is a “Long Life” type capacitor, meaning it contains a larger amount of electrolyte within the capacitor body, allowing it to have a higher tolerance to temperatures and faster charge/discharge cycles. It has a small size and is insulated with a plastic sleeve to prevent short-circuiting.
The MALREKA00PB347DL0K is primarily used in switching power supplies and LCD monitors where high frequency switching and ripple current noise suppression are needed. It is also suitable for applications in converters, inverters, HIDs, and ballast circuits. Additionally, these capacitors are commonly used in AC/DC current rectification and EMC applications.
The working principle of the MALREKA00PB347DL0K is based on the phenomenon of electrolytic polarization. When a voltage is applied, the current flows into the capacitor, and the resulting reaction creates a layer of oxide on the aluminum foil surface electrolytically. This oxide film serves as the capacitance layer, producing an isolated field and charge distribution. The oxide film also acts as a barrier between the anode and cathode plates, preventing current from flowing between them and allowing the capacitor to maintain its capacitance over time.
The oxide film also provides the MALREKA00PB347DL0K with its high dielectric strength. This voltage breakdown voltage is extremely important for application requiring high reliability such as in safety equipment or medical instrumentation. Additionally, the mechanical strength of the foil also helps with the breaking down of the oxide film due to sharp current surge or vibration.
In conclusion, the MALREKA00PB347DL0K is an aluminum electrolytic capacitor with a rated voltage of 450 volts DC and capacitance of 4.7 µF. It has a long-life design and is primarily used in switching power supplies and LCD monitors, AC/DC current rectification and EMC applications. The working principle of the capacitor is based on electrolytic polarization and the oxide film created on the aluminum foil surface. The oxide film is an isolated field and charge distribution and acts as a barrier between the anode and cathode, allowing the capacitor to maintain its capacitance. It also provides the capacitor with its high dielectric strength, making it suitable for high reliability applications.
