Film capacitors are widely used in appliance, industrial, automotive, telecommunications, defense and medical industries. They are usually composed of two overlapping thin metal sheets, and an insulating film that is wound into a cylindrical structure. The use of film capacitors is not limited to any specific industry, and they are used in a variety of applications. One such application is the ECW-H12132HV, a film capacitor suitable for high-voltage applications.

The ECW-H12132HV series consists of a high-voltage DC-link film capacitor that is designed for power conditioning applications and high-voltage AC-link applications. It is composed of a non-inductive metallized polyethylene film capacitor, and it is designed for DC-link applications up to 6.5kV. It is available in several standard sizes, and its high-voltage, self-healing capa design makes it an ideal choice for high-voltage applications.

The working principle of the ECW-H12132HV is simple. When a voltage is applied across the two electrodes, a large electric field is generated inside the capacitor. This electric field, in turn, causes the polarized charges on the film to migrate, creating a positive and negative charges on opposite sides. These charges attract each other, forming an equipotential field between them.

The second important working principle of the ECW-H12132HV involves the current-limiting diodes placed around the capacitor. In the presence of higher currents, these diodes help to reduce the voltage across the capacitor and protect against overvoltage. The use of current-limiting diodes prevents the capacitor from discharging too quickly and limits the maximum charge stored in the capacitor, thus protecting it from damage.

The ECW-H12132HV series of film capacitor is suitable for high-voltage applications due to its low-inductance design and its ability to self-heal. These characteristics make it a great choice for various power conditioning applications as well as a reliable choice for high-voltage AC-link applications. Additionally, its high-voltage, self-healing capability ensures that the capacitance remains stable even when exposed to extreme temperatures and vibrations.
