Film capacitors, commonly known as plastic film capacitors, are widely used in various electronic circuits due to their excellent performance. The ECW-F4155HL has come to the fore in recent years and become one of the most widely used film capacitors. This article introduces the application fields and working principle of ECW-F4155HL.

ECW-F4155HL Application Fields

The ECW-F4155HL film capacitors, based on the materials used, are divided into five categories, namely, Polypropylene (PP), Polyetheylene (PE), Polycarbonate (PC), Polyphenylene Sulphide (PPS) and Polyurethane (PU). These five categories have different uses:

• Polypropylene (PP): This type is mainly used in power electronics, such as variable frequency and DC drives, switch power supplies, home appliances, UPS and lighting energy.
• Polyetheylene (PE): PE film capacitors are suitable for high-end audio filtering and signal coupling, especially for industrial and instrumentation.
• Polycarbonate (PC): PC film capacitors are mainly used in computer, car and communication industries.
• Polyphenylene Sulphide (PPS): PPS film capacitors are mainly used in the automotive audio system, engine control and power supply.
• Polyurethane (PU): PU film capacitors are used in the medical power supply and aerospace power electronics applications.

ECW-F4155HL Working Principle

The ECW-F4155HL film capacitor is a kind of monolithic capacitor which has a construction with two metal electrodes and multiple dielectric layers in between. The dielectric layers take a thin film format which is wound between the two metal electrodes. The dielectric layers in between the electrodes are what give the capacitor its capacitance.

In practice, plastic film capacitors consist of two metal electrodes, which are coated with an insulating layer in between two layers of plastic film. This plastic film layer provides the capacitance and dielectric strength of the capacitor. When an alternating current is applied to the capacitor, current flows through the electrodes, creating a charge across the dielectric layer that creates a voltage potential.

The dielectric material used in the ECW-F4155HL film capacitor is usually Polyphenylene sulphide (PPS) and Teflon (PTFE). The dielectric material has high temperature resistance and high voltage withstand, making it ideal for use in a wide range of applications. The capacitance range for the ECW-F4155HL is from 1nF to 100nF, with a voltage rating of up to 20kV.
