Film capacitors, also known as plastic film capacitors, are capacitors made from thin plastic films. They are widely used in various applications to store electrical energy and to filter high frequencies in electronic circuits. The ECW-F4563JLB Film Capacitor is a type of plastic-film capacitor designed for high-performance and long life applications. This article will discuss its application field and working principle in detail.

Application Field

The ECW-F4563JLB Film Capacitor is designed for use in power electronics, lighting and industrial automation, automotive delivery, medical and military applications, among other fields. It is used in numerous circuits to store or erase charge, and serves as a basic component for many types of electronic device. Its low losses, high insulation resistance, and reliability make this capacitor especially suitable for power conversion systems and other critical applications. It can be used in power factor correction, active voltage sag, and PFC capacitors.

Furthermore, ECW-F4563JLB is highly advantageous for its capacity to withstand high temperature, and its application covers many different temperature zones. Its extended temperature range from -40°C to +105°C ensures excellent performance in extreme temperature conditions. In addition, the capacitor is available in UL94V-0 compliant, halogen free materials to meet the requirements for environmental friendly products. The capacitor also has a wide voltage range from 100V to 500V and capacitance ratings ranging from 1.0µF to 45.0µF.

Working Principle

The ECW-F4563JLB Film Capacitor is an electrolytic capacitor with a plastic film as the dielectric. The plastic film acts as the insulating barrier between two metal plates, connected to the positive and negative terminals. The electrons in the dielectric are free to move but cannot pass through the insulator. When a voltage is applied to the capacitor, the electrons are attracted to the positive terminal while the negative terminal is repelled. This creates an electric field between the two plates and charges the capacitor.

As the voltage increases, the electric field gets stronger and more electrons are attracted to the positive terminal while the negative is repelled. This creates a larger charge on the capacitor and stores more energy. The capacitor can then be discharged by completing a circuit such that the electrons are free to move. The charge then dissipates while the electrons move back and forth between the plates.

The ECW-F4563JLB Film Capacitor is a durable and reliable capacitor due to its dielectric of thin plastic film that can withstand high fluctuations in temperature and voltage. The capacitor has high insulation resistance that prevents leakage and can withstand extreme temperatures. The capacitor also has a low dissipation factor for circuit protection, and its extended temperature range from -40°C to +105°C allows it to remain stable in a wide range of environmental conditions.

In conclusion, the ECW-F4563JLB Film Capacitor is a type of plastic-film capacitor designed for high-performance and long life applications. Its wide range of features and reliability make it suitable for many types of applications and operators, from power electronics to medical and military applications. Its ability to withstand high temperatures, low losses, and high insulation resistance make it the ideal choice for any critical power-conversion applications.
