Film capacitors, which are also known as film dielectric capacitors or polymer film capacitors, are composed of multiple layers of thin plastic fi between layers of conductive electrodes. The main materials used to construct these components are Mylar (polyester or PET), Teflon (PTFE), nylon, and polycarbonate. They possess advantages such as higher insulation resistance, higher heat resistance, low dielectric losses, and stability over a wide range of temperatures and frequencies. The ECW-HA3C123HB is a specific type of film capacitor that is part of a larger family known as rectangular film capacitors.

Overview

The ECW-HA3C123HB is a rectangular film capacitor that is designed for high dielectric strength and reliable operation. It features a voltage stability of up to 6kV, a capacitance range of 3.3 to 9.9 microfarads, and has a maximum rated working frequency of 110MHz. Additionally, its high insulation resistance ensures minimal heat coefficient due to low dielectric losses. These features make it well-suited for many applications.

Application Field

The ECW-HA3C123HB is an ideal choice for applications that demand reliable operation, high insulation strength, low dielectric losses, and stability. Its wide capacitance range of 3.3 to 9.9 microfarads makes it suitable for many different uses, including as an energy storage and filtering device, in communication systems, and in audio equipment. Its rectangular design allows it to fit more easily into circuit boards, and its large voltage stability ensures that it will not suffer from damage when exposed to higher voltages.

Working Principle

The working principle of a film capacitor is based on the principle of electrostatic induction. When voltage is applied between its electrodes, an electric field is generated due to the dielectric layer in between. This electric field generates an opposing electric field, which stores the energy of the applied voltage and forms a capacitance. The ECW-HA3C123HB is a rectangular film capacitor with three layers, each of which is responsible for specific functions related to capacitance. The top and bottom layers, which are known as the electrodes, are responsible for collecting and emitting the charge. The central layer, known as the spacer, is responsible for maintaining the distance between the two electrodes and for providing the necessary insulation for high-voltage operation.

Conclusion

The ECW-HA3C123HB is a remarkable film capacitor that is suitable for a variety of applications. Its wide capacitance range and high insulation strength make it well-suited for applications such as energy storage, filtering, and communication systems. Its rectangular design fits well into circuit boards, and its voltage stability ensures that it can withstand higher voltages without damage. Its working principle is based on electrostatic induction and its three layers are responsible for the various functions of capacitance.
