Introduction

Film capacitors, also known as polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyester (PET), polyethylene naphthalate (PEN), polyphenylene sulfide (PPS), polytetrafluoroethylene (PTFE), or plastic capacitors, are capacitors that use plastic films as the dielectric medium. They are widely used in a range of applications, from low-frequency AC line filtering to high-frequency telecommunications, from hair dryers to electric cars.The 935C4W10K-F is a film capacitor used in many of the aforementioned applications. This article will discuss the application field and working principle of the 935C4W10K-F in order to understand the device better.

Application Field

The 935C4W10K-F is a film capacitor used in various applications. These include power supplies and audio-video applications, such as home cinemas, primary and secondary power filtering, and supply line decoupling.The 935C4W10K-F is also used in high-frequency switching power supplies. Switched-mode power supplies are the most popular choice for powering electronics with a constant voltage and current. The 935C4W10K-F helps eliminate high-frequency noise generated by switched-mode power supplies by damping the power supply output current. In addition, the 935C4W10K-F is an important component in variable speed drives and motor control.The 935C4W10K-F is widely used in the telecommunications industry as well. It is used in high-frequency and broadband applications, including in optical systems, for signal conditioning and EMI/RFI filtering. It is also used in base station antenna circuits to reduce ESR and improve the antenna efficiency.

Working Principle

The 935C4W10K-F is a film capacitor which utilizes a thin dielectric material that is sandwiched between two metal plates. When a voltage is applied to the device, the dielectric material gets polarized, resulting in a stored electrical energy that is proportional to the applied voltage. This stored energy is then discharged when the voltage is removed, providing a continuous flow of current.The 935C4W10K-F is composed of two metal electrodes on both sides of the film. These electrodes create an electric field that polarizes the dielectric material, causing an accumulation of charge. The amount of charge stored depends on the capacitance of the 935C4W10K-F, which is determined by the area of the electrodes and the distance between them. When AC voltage is applied to the 935C4W10K-F, the charges build up on the electrodes, creating a potential difference between them and resulting in a magnetic field. This magnetic field helps dampen the AC voltage, allowing for smoother and efficient power transmission.

Conclusion

The 935C4W10K-F is a film capacitor used in a variety of applications such as power supplies, audio-video applications, and telecommunications. Its working principle is based on the polarization of the dielectric material between the two metal electrodes, which stores electrical energy proportional to the applied voltage. This stored energy is then discharged when the voltage is removed, providing a continuous flow of current which is used to dampen AC voltage in various applications.
