Aluminum Electrolytic Capacitors

The ERWL351LGC682MDK0M is an aluminum electrolytic capacitor. It is a type of capacitor, an electrical component commonly used in electronics circuits, that is capable of storing an electrical charge. As compared to other types of capacitors, aluminum electrolytic capacitors feature higher capacitance and greater energy density. They are also suitable for applications where a high pulse-load current is required.

Application Field

Aluminum electrolytic capacitors, such as the ERWL351LGC682MDK0M, are typically found in a variety of consumer, industrial and military applications. Consumer applications include TVs, gaming consoles, radios, speakers, digital cameras, laptops and mobile phones. Industrial applications are varied and can include motor drives, welding equipment and electronic testing equipment. Military electronics that use aluminum electrolytic capacitors can include communication systems and weapons guidance systems.

Working Principle

Aluminum electrolytic capacitors, like the ERWL351LGC682MDK0M, are cylindrical, can-shaped units typically composed of a metalized aluminum anode, a plastic film cathode, and a liquid electrolyte. These capacitors utilize a dielectric made of aluminum oxide, which provides high and reliable capacitance values. As electricity passes through the device, the oxide layer absorbs the electric charge and thus stores the energy. When full charge is reached, the capacitor acts as a filter, blocking current from passing through it.

Advantages of Aluminum electrolytic Capacitors

Aluminum electrolytic capacitors such as the ERWL351LGC682MDK0M have several advantages over other types of capacitors such as ceramic or film capacitors. Firstly, aluminum electrolytic capacitors typically offer larger capacitance values than ceramic or film capacitors of similar size. Secondly, they can cope with high voltage up to 850 volts depending on the size. And lastly, they are capable of handling high energy density with long service life.

Disadvantages of Aluminum electrolytic Capacitors

Despite the many advantages of aluminum electrolytic capacitors, they also have some drawbacks. For example, they are prone to high operating temperatures, limited life-time expectancy, and limited surge withstanding capabilities. Furthermore, they have low equivalent series resistance, and require their own circuit protection when mounting.

Conclusion

The ERWL351LGC682MDK0M is a type of aluminum electrolytic capacitor, which is commonly used in a variety of consumer, industrial and military applications. These capacitors offer larger capacitance and higher energy density compared to other types of capacitors, though they are prone to limited life-time expectancy and higher operating temperatures. Careful consideration of the application and environment are therefore essential to ensure that these capacitors are used in the most appropriate way.
