Aluminum electrolytic capacitors, also commonly referred to as electrolytic capacitors, are unique electronic components with deep grooves and the ability to store electrical energy. The 381LR680M420H012 model in particular, is a type of aluminum electrolytic capacitor which is popular among many fields. In this article, we will explore the application fields and working principle of this model.

Application Fields

The 381LR680M420H012 model aluminum electrolytic capacitors are mainly used in consumer electronics and automotive electronics fields. These capacitors are capable of storing and releasing a relatively large amount of energy, and this makes them an appealing choice in many electronic circuits.

In consumer electronics, these capacitors are commonly used in power supplies and for motion control. The capacitors can be used to filter direct current power supplies and store energy that can be later used to power electric motors. The capacitors combined with one another can also form a blocking layer to protect the circuit from high voltage transients.

In automotive electronics, these capacitors are used for a variety of tasks, including powering and controlling vehicle electronic systems. They are also commonly found in vehicle power supplies, and are used to filter out voltage transients.

Working Principle

Aluminum electrolytic capacitors are based on a simple principle: they are comprised of two aluminum electrodes that are immersed in an electrolytic solution. The electrolytic solution contains ions that create an electrical charge when subjected to a potential difference. This charge will be stored in the aluminum electrodes which will form a capacitor.

The 381LR680M420H012 model aluminum electrolytic capacitors achieve this process by using a special process called “anodization”. During this process, one of the aluminum electrodes will be oxidized, resulting in an oxide coating. This coating creates a dielectric field that increases the capacitance of the capacitor.

The capacitors also feature built-in safety devices, such as the auto resetting fuse located in the anode. This fuse will protect the capacitor from excessive voltage, and will help to ensure its performance and safety in different application fields.

Conclusion

The 381LR680M420H012 model aluminum electrolytic capacitors are an excellent choice in many electronic and automotive fields, thanks to their ability to store energy and their built-in safety features. The working principle of this model is based on anodization, which creates a dielectric field in the aluminum electrodes that increases the capacitance of the capacitor. As such, this model is a reliable choice for those seeking reliable capacitors.
