Film capacitors, also known as part of the plastic film capacitors, are made by winding a marcelled film or paper-plastic composite film (Dacron and polyethylene) dielectric layer with two metal layers (aluminum, copper, zinc) of conductive electrodes as the medium. It uses vacuum aluminum evaporation and electroplastic deposition process to make metal layer. Film capacitors are one of the most important parts in the circuit, and their working principle is to store electrical energy. Now, they are widely used in the fields of computers, communication equipment, medical equipment and other electronic devices.

ECH-U1C273GX5 Application Field and Working Principle

ECH-U1C273GX5 is a type of film capacitor with metalized polypropylene dielectric material, which is widely used in automotive and industrial fields, such as battery cells, capacitors and electric motors. It also possesses high general-purpose power ratings and high frequency characteristics, which makes it highly reliable in most application fields.

In terms of working principle, both of its electrodes are connected to the two external circuit elements, forming two internal connections and resulting in two capacitances as shown in the diagram below. When a voltage is applied to these two connections, a charge tends to flow between them, creating an electric field in the process. This electric field, through the capacitance, produces an electric polarization of the dielectric material and the corresponding negative electric charge on the opposite electrode. The electric polarization increases the strength of the electric field and results in a smaller electric charge being stored in the same amount of space, thus achieving the goal of capacitance.

Because the dielectric material of ECH-U1C273GX5 is a high-grade polypropylene, which can resist high temperature and voltage, ECH-U1C273GX5 has excellent overall characteristics in terms of capacitance, breakdown voltage and temperature coefficient of capacitance. According to the test and actual test data, ECH-U1C273GX5 has a good temperature coefficient after reaching the rated temperature, which can reach -25~120°C, and has a superior insulation resistance and current resistance. In addition, its filtering performance is also very outstanding, which can be applied to various occasions, such as the filtering of electrical noise.

In conclusion, ECH-U1C273GX5 is a type of film capacitor with superior performance over almost all other types of capacitor, especially in automotive and industrial applications. Its excellent insulation resistance, current resistance and filtering capability make it suitable for various applications and contribute to its popularity in the market.
