Film Capacitors

Film capacitors are one of the most important components in today’s electronics industry. They are used in a variety of applications ranging from computers and telecommunications to aerospace and automotive applications. One of the more popular film capacitors is the PME271-M660KR30.

PME271M660KR30 Application Field

The PME-271-M660KR30 film capacitor is a high voltage part that is good for applications such as bypass, filtering and buffering in power supplies and line circuits. It is also a good choice for resonant and rectifier circuits where low ESR is needed. The capacitor has a working voltage of 6KV and a capacitance of 0.2μF. It also has an operating temperature range from -40°C to +110°C.

PME271M660KR30 Working Principle

The working principle of film capacitors is based on the physical mechanism of electrostriction. This means that when an electric field is applied, a mechanical force is generated inside the dielectric, causing it to contract or expand. This phenomenon is the basis of the capacitive effect in film capacitors. The dielectric material used in film capacitors varies depending on the application, but typically includes polypropylene, polyester, polycarbonate, and polyethylene films.

The electrostrictive effect creates a dielectric field in an electric current. This means that when a voltage is applied, the capacitor’s dielectric is pulled inwards, creating an electric field within the transparent foil. This electric field is then stored in the form of energy. When a current is applied, the capacitor will discharge this energy back into the circuit.

The PME271-M660KR30 film capacitor is a stack film capacitor. This means that the dielectric films are stacked one after another, separated by a thin dielectric layer. This design provides higher capacitance, but also increases the voltage rating. This capacitor has a non-encapsulated structure, meaning that it has fewer components. This makes it more durable, but also more prone to sudden failures.

Conclusion

The PME271M660KR30 is a high voltage film capacitor that is used in many applications. It is a stack film capacitor with a voltage rating of 6KV and a capacitance of 0.2μF. Its working principle is based on the physical mechanism of electrostriction, where an electric field is applied, creating a dielectric field within the transparent foil. This capacitor has a non-encapsulated structure and is suitable for applications such as bypass, filtering and buffering in power supplies and line circuits.
