Introduction

Film capacitors (also known as plastic film capacitors) are capacitors made of a dielectric thin film. It is a device used to store electric energy. Film capacitors are far superior to other types of capacitors in terms of features such as low ESR, low temperature coefficient, long life, high heat resistance, and excellent self-healing ability.The 405PHB400K2H model is a highly reliable, thin-film capacitor designed for high voltage switching applications. It features a low ESR, high ripple current and ripple voltage characteristics, high insulation resistance, high thermal resistance, and excellent frequency characteristics.

Construction and Working principle

Film capacitors are constructed by winding two or more layers of plastic film coated with a conductive metal. The. film is used as the dielectric material in the capacitors and is chosen for its high breakdown voltage and insulation properties. A vacuum or dry air is used to maintain the desired insulating properties of the film.The working principle of a film capacitor is based on the same principle as any other capacitor. When a voltage difference is applied across the capacitor terminals, the electric field generated between the charged plates causes electrons to flow from one plate to the other, resulting in the capacitor charging. The charge stored in the capacitor is proportional to the applied voltage and capacitance of the capacitor. Conversely, when the voltage is removed, the electrons flow back to their original positions and the capacitor discharges.

Applications

Film capacitors are used in a wide variety of electronic applications, from televisions and radios to cell phones and computers. The 405PHB400K2H can be found in various high-voltage switching applications, such as motor controls, inverters, power supplies, and more.The 405PHB400K2H has been designed for high-voltage applications by offering low ESR, high ripple voltage and ripple current, excellent frequency characteristics, high insulation resistance, and high thermal resistance. It is a reliable choice for high voltage switching applications, offering superior performance under both high and low temperatures.

Conclusion

The 405PHB400K2H is a reliable and highly efficient film capacitor, designed for high voltage switching applications. It offers a range of features and advantages such as low ESR, high ripple voltage and ripple current, excellent frequency characteristics, high insulation resistance, and high thermal resistance.
