Aluminum electrolytic capacitors are electrical components that are mainly used to store energy. These capacitors are usually composed of two or more metal plates that are separated by an electrolytic solution. The separation between the plates creates a dielectric barrier that prevents the electrical energy from dissipating. The most common type of aluminum electrolytic capacitors are axial leaded and use an aluminum oxide dielectric impregnated with a liquid electrolyte.

The specific model of aluminum electrolytic capacitor that is covered in this article is the 381LX121M315J012. This model is a type of axial leaded electrolytic capacitor, meaning that it has two metal plates that are separated by an electrolytic solution, and two leads which are connected to both sides of the capacitor plate for electrical connection. The 381LX121M315J012 has a rated capacitance of 1,200 uF and is capable of operating at a maximum working voltage of 450 VDC.

The primary purpose of the 381LX121M315J012 is to store electrical energy. This type of capacitor is ideal for applications requiring large amounts of energy storage such as power supplies, motor drives, and in some cases, the powering of computer systems. Its small size and low cost also make it an attractive option for high-frequency filters, timing circuits, and input and output inter-stage coupling circuitry.

The working principle behind an aluminum electrolytic capacitor is relatively simple. When electrical current passes through the two plates, an electric field is created which causes electrons to be pushed into the plate of positive charge. This creates an electric charge imbalance between the two plates. When a voltage is applied to the capacitor, the pressure that’s created in the electric field causes an electric current to flow. This current is stored in the capacitor until the voltage is removed, in which case the electrons will return to their original position.

Due to its high working voltage and large capacitance, the 381LX121M315J012 aluminum electrolytic capacitor makes for an ideal energy storage option for a variety of applications. Its small size and low cost also make it an attractive option for applications which require high-frequency filters, timing circuits, and input and output inter-stage coupling circuitry. This capacitor is extremely reliable and can be found in a variety of electronic devices and products.
