Film Capacitors

Film capacitors, also known as film dielectric capacitors, are a type of capacitors primarily constructed of thin plastic films instead of the usual paper, mica, or ceramic dielectrics. While this construction approach is more complicated, it results in superior electrical characteristics, enabling the capacitors to be used in the most demanding applications. MPXB125K305H is one such type of film capacitors, and it is commonly found in different applications due to its high performance in various conditions.

To better understand the application field and working principle of MPXB125K305H, let us first look at its different features. This capacitor is manufactured using metallized polypropylene (or PP) film, and has a volumetric capacitance of 0.125kV to +105°C. It is best known for its low loss characteristics and high temperature stability, making it suitable for use in several high voltage and high temperature applications. Furthermore, this type of capacitor also offers excellent electrical insulation performance and arc-over prevention. With minimal self-inductance, it is commonly used in filter circuits, pulse forming networks, and in driving circuits for high frequency applications.

Now that we have an idea of the features of MPXB125K305H, let us learn how it works and in what applications it can be used. Fundamentally, capacitors store electric charge and release it when needed. Film capacitors are created when two conductive metallic surfaces are separated by a dielectric layer. In the case of the MPXB125K305H, this dielectric material is polypropylene. Basically, to create an electric field, a voltage difference is set up between the two metal surfaces. When the capacitor is charged by this voltage, the electrons will accumulate in one of the metal surfaces, and an electric field is set up in its dielectric material, hence storing electric charge. To discharge this capacitor, the voltage is reversed. This reverse voltage creates a negative charge at one of the surfaces, while the other metal surface accumulates a positive charge. As a result, the electric field is eliminated and the capacitor is effectively discharged.

The result of the above-mentioned working principle is that the MPXB125K305H is extremely reliable and has a predictable behavior in most applications. This makes it an ideal choice for high voltage and high temperature applications, such as in DC motors, power factor correction circuits, and pulse forming networks, just to name a few. The capacitor is also ideal for use as a buffer in communication systems, owing to its arc-over prevention capability. Finally, the capacitor is also widely used in audio and video equipment, as well as in DC power sources.

As a film capacitor, MPXB125K305H is a reliable and cost-effective solution for many different applications. Its low loss characteristics and high temperature stability make it ideal for high voltage and high temperature applications. Furthermore, its arc-over prevention capabilities make it suitable for pulse forming networks and communication systems. Finally, the capacitor is also widely used in audio and video equipment, as well as in DC power sources. All in all, it is clear that MPXB125K305H is an ideal choice for a wide variety of applications.
