Aluminum electrolytic capacitors are common components in electronic circuits to store electric energy temporarily and filter unwanted noise and signals. 380LX681M080H012 is an aluminum electrolytic capacitor designed for use in high-temperature and high-humidity applications. This article will discuss its application field and working principle.

Application Fields

The 380LX681M080H012 aluminum electrolytic capacitor is specifically designed for applications in appliances, instruments and automated production equipment that are used in harsh environments. It is designed for high temperature (up to 105°C) and high humidity (RH 95% to 95%) applications. It has superior performance in voltage-holding, low leakage current, and a high relay life. It is a polarized device, meaning the positive and negative terminals must be connected correctly, which makes it suitable for both AC and DC applications.

The 380LX681M080H012 capacitor is available in different sizes and capacitance levels, ranging from 0.1µF to 47µF. The higher capacitance values provide more storage capacity, which is important for filtering digital noise.

Working Principle

The 380LX681M080H012 aluminum electrolytic capacitor is a polarized device that uses an electrolyte to store charge. It consists of two metal plates (an anode and a cathode) separated by a thin dielectric material. One plate is covered with an absorbent layer of organic material called an electrolyte. The two plates are connected by a wire that acts as an additional counterelectrode.

When voltage is applied to the capacitor, the electrolyte reacts with the metal plates to form a thin dielectric layer. This layer of insulation effectively “blocks” current from passing through the plates. When a current is applied to the capacitor, the dielectric layer breaks down and allows current to flow, which stores energy in the form of electrical charge.

When the capacitor is disconnected from the power source, it maintains the charge stored in the plates as the dielectric layer is self–healing. The 380LX681M080H012 capacitor has a unique self–healing property that allows the dielectric layer to rapidly heal in the event of a breakdown.

The 380LX681M080H012 aluminum electrolytic capacitor is an ideal choice for high-temperature and high-humidity applications. Its superior performance in voltage-holding, low leakage current, and a high relay life make it a reliable component for a wide range of applications. It is an important component used in devices and equipment operating in harsh environments.
