Film Capacitors

Film capacitors are capacitors that rely upon a plastic film as the dielectric. As a class, film capacitors have excellent stability against environmental conditions, are not subject to corrosion, and are relatively immune to vibration due to their low inherent mechanical compliance. Operating temperature ranges are often as high as +200°C/+400°F for some of the polyester and polypropylene dielectrics.

In this article, we will discuss MKP383430063JIM2T0 application field and working principle, and how it fits into the family of film capacitors.

Application Field

MKP383430063JIM2T0 is a distance-controlled metallized film capacitor which is especially suitable for DSL lines. This product is intended for symmetrical DSL transmission lines and is particularly suitable for ADSL, VDSL lines, and other applications. MKP383430063JIM2T0 is an ideal choice for telecommunications applications and is currently used in digital loop carriers and various DSL/ISDN/Ethernet/VDSL systems.

MKP383430063JIM2T0 has a large capacitance range from 28pF to 1000pF, rated voltage from 0.5KV to 3KV, and insulation resistance greater than or equal to 1000Mohm@120V. It is a reliable and excellent distance controlled metallized film capacitor.

Working Principle

The MKP383430063JIM2T0 is a metallized film capacitor with a single winding around the plastic film. The film used to construct the MKP383430063JIM2T0 is made from polypropylene, a type of plastic generally used to manufacture capacitors due to its low dielectric loss and high degree of frequency stability. The winding of this capacitor is connected to two adjacent metal electrodes.

These two electrodes are connected to the external electric circuit via a pair of leads. When the two leads are connected to an electric circuit, the electric current from the external circuit flows through the winding and creates an electric field. This electric field in turn causes a separation of charge across the film and further creates an electric field between the two electrodes. This electric field causes the capacitor to store energy.

At the end of each electrical cycle, the amount of energy stored in the capacitor diminishes as the electric field between the two electrodes dissipates. This is the fundamental principle on which the MKP383430063JIM2T0 operates, but as mentioned earlier, the polypropylene film makes the capacitor remain relatively stable against environmental conditions, as well as being highly immune to vibration.

Conclusion

The MKP383430063JIM2T0 is a distance-controlled metallized film capacitor that is often used in DSL lines. It is available in a range of capacitance, with a rated voltage from 0.5KV to 3KV, and it is constructed using a polypropylene film as its dielectric. It is highly stable to environmental conditions and resistant to vibration, and it operates on the principle of an electric field creating a separation of charge across the film, thus allowing the capacitor to store energy.
