Film Capacitors

Film capacitors are specialized capacitors where the dielectric is a thin plastic film. Film capacitors are extensively used in electrical and electronic applications, mainly due to their excellent electrical properties, such as high insulation resistance, high dielectric strength, low dielectric absorption, and excellent dv/dt capability, making them particularly suitable for high frequency and pulse applications. The ECW-F4155JL is one of the most popular types of film capacitors, widely used for various applications and specifications. This article will explain the application field and working principle of the ECW-F4155JL film capacitor.

Application Field

The ECW-F4155JL is a large-size, surface mountable film capacitor, specially designed for power electronic drives. It is designed to provide stable, low loss performance for power electronic applications. With its wide operating temperature range (-55°C to +125°C) and high ripple current capability, it is suitable for use in a wide variety of high-frequency and high-power applications, and is ideal for motor drive systems, photovoltaic inverters, PV systems, and other transients related applications.

The ECW-F4155JL has a high working voltage (450 VDC) and a wide frequency range (50 Hz to 100 kHz). Its excellent dv/dt capability and high insulation resistance, low equivalent series inductance (ESL), and low parasitic capacitance ensure superior performance and reliability. The high level of electrical performance combined with its solid construction makes it ideal for applications requiring long lifetimes and high reliability.

Working Principle

The working principle of film capacitors is based on the Coulomb’s law, which states that the electric force between two charged particles is proportional to the product of their charges and inversely proportional to the square of their separation. The Coulomb’s law plays an important role in the design and functionality of film capacitors. In essence, capacitance is created between two metal plates separated by a dielectric material (such as the plastics used in film capacitors).

As current flows through the metal plates, the charge of electrons on each plate builds up and creates an electrostatic field between them. When the voltage across the plates is equal, the electric field is neutralized and no further charge is transferred. This electric field stores energy, which is released as the capacitor discharges. The amount of stored energy is proportional to the capacitance of the capacitor.

The ECW-F4155JL is designed to provide high levels of reliable performance and electrical properties. Its solid construction ensures a consistent electrical performance and high dv/dt capability. Its wide operating temperature range and high ripple current capability make it suitable for numerous high-frequency and high-power applications.

In conclusion, the ECW-F4155JL is a popular type of film capacitor, widely used for various applications and specifications. It is designed to provide stable, low loss performance for power electronics applications, with an impressive working voltage and frequency range. Its excellent dv/dt capability and high insulation resistance, low ESL and low parasitic capacitance make it a reliable choice for motor drives systems, photovoltaic inverters, PV systems and other transients related applications.
