Introduction to Film Capacitors

Film capacitors are also known as film dielectric capacitors, AC capacitors, DC capacitors, or polyester capacitors, depending on the material they\'re made of. Film capacitors are made of a thin plastic film as the dielectric (insulating phase) medium. This thin, flexible film is sandwiched between two plates of metal foil or metallised film.The resulting capacitor is often cylindrical and has a variety of mounting options as well as a variety of shapes and sizes. It is an ideal choice for capacitors used in harsh electrical environments, due to its extreme stability. Given its various advantages, it is no wonder that film capacitors are gaining in popularity for a variety of industrial and consumer applications.

105PHB850K2H Application Field and Working Principle

The 105PHB850K2H is an MPX Polyester Capacitor made from 105°C high temperature polyester film. This makes it a reliable, high quality capacitor option for use in high temperature applications.The 105PHB850K2H is a capacitors used in a variety of applications. It is used primarily for applications such as motor drives, welding equipment, and power supply applications. The capacitors can also be used for filtering or coupling/decoupling applications.At the heart of the 105PHB850K2H MPX Capacitor is a polyester film with two metallic layers. The two metalized layers are attached to one another and to a film substrate. The film substrate acts as the dielectric, allowing the capacitance to remain stable over a wide range of temperatures and frequencies. This makes the capacitors suitable for many different applications in harsh environmental conditions.The electrical connection between the two metal layers is determined by the specific application requirements. The 105PHB850K2H MPX Capacitor has two electrical connections: One end that is connected to the anode (positive) and one end that is connected to the cathode (negative). The voltages and currents supplied to these two dedicated connections determine the operation of the capacitor.The 105PHB850K2H is used in applications that require precise capacitance levels and stable operation in extreme temperatures. It is also characterized by its low equivalent series resistance (ESR), which allows for a wide range of frequencies and high-speed electrical processes. The capacitive worth of the film is determined via its metallized layers and the overall capacitance value is limited only by the dielectric properties of the film.When the two charges within the capacitor meet, the dielectric supports a capacitive electric field, resulting in a change in the electrical energy stored in the capacitor and manifesting as a voltage across its terminals. This phenomenon, known as AC ripple, is the effect of a capacitor’s working principle.

Conclusion

The 105PHB850K2H MPX Polyester Capacitor is a film capacitor designed for use in high temperature and harsh electrical environments. It works by allowing two charges to meet in a dielectric medium, creating an electric field that manifests as AC ripple, changing the stored energy and resulting in a voltage across its terminals. This makes the 105PHB850K2H MPX Capacitor ideal for use in filtering and coupling/decoupling applications, motor drives, welding equipment, and power supply applications.
