Film Capacitors

MKT1817310014W is a widely used film capacitor that offers many advantages that make it a preferred choice for a variety of applications. Film capacitors are also known as metallized polyester capacitors, as the metallization of the film is a crucial part of their platform. The MKT1817310014W has a 474VAC rating and is a Class X1, X2 and Y2 type device with excellent electrical performance and dielectric strength.

Application Field

The MKT1817310014W can be used in a variety of applications such as high-frequency AC mains, snubber circuits, applicances, AC motor controls, and more. With a maximum ripple current rating of up to 250V AC, this capacitor offers low ESR, low loss, excellent noise suppression, and very low inductance making it an ideal choice for high frequency networks. Additionally, this type of capacitor is capable of withstanding harsh environments and extremes temperatures well above its rated temperature.

Working Principle

The MKT1817310014W utilizes a metallized polyester dielectric. This type of dielectric has a very high breakdown voltage and can provide excellent results in rating for acoustic noise suppression and high frequency AC applications. As the capacitor is a Class X1, X2, and Y2 type device, it uses a dual layer metallized polyester film for its insulation. This dual layer construction offers improved performance in applications with high AC ripple currents.

The capacitor has two electrodes, which are held in close proximity to one another by a spacer. This spacer stops the interaction between the two electrodes in AC applications. When an AC voltage is applied to the capacitor, the oscillating electric field produces an effect where the capacitor charge and discharge current is alternated between the two electrodes. This is known as a capacitive effect.

The capacitive effect enables a capacitor to store electrical energy, as the capacitor is able to store charge and release it when required. This is the working principle of the MKT1817310014W capacitor. In summary, this capacitor is able to store energy when an AC voltage is applied to it and provide noise suppression, low ESR, low loss, and very low inductance in high frequency applications.

Conclusion

To sum up, the MKT1817310014W is a popular film capacitor with a high breakdown voltage that can offer excellent performance in many applications. This type of capacitor has a dual layer metallized polyester film insulation, which can handle harsh environments and work very well in AC applications. The capacitor works by storing energy in the form of a capacitive effect, enabling it to provide noise suppression, low ESR, low loss, and very low inductance in applications with high AC ripple currents.
