Film capacitors, sometimes called plastic film capacitors, are a type of capacitor with a very thin plastic dielectric, typically of polypropylene or polyethylene terephthalate film. The MKT1817310015F is a film capacitor that is especially well-suited for pulse applications, where the requirement is for very low dielectric losses and very good temperature characteristics. In this article, we’ll discuss the application field and working principle of the MKT1817310015F.

Application field

The application field of this type of capacitor is very wide, it ranges from standard appliance and motor control applications, to high-speed switching power supplies, to telecommunication systems. The capacitors are extremely useful for motor control applications due to their excellent temperature characteristics, which make them suitable for wide temperature range operation. Additionally, the capacitors have extremely low dielectric losses, making them ideal for pulse applications.

In terms of electronics, the MKT1817310015F is commonly used as a bypass capacitor, a timing capacitor, and a filtering capacitor. As a bypass capacitor, the capacitor is used to store energy and provide an alternate current path to ground, while as a timing capacitor it is used to trigger a timer circuit. The capacitors are also commonly used as filtering capacitors in high-frequency switching applications such as radio-frequency (RF) circuits.

Working principle

The working principle of the MKT1817310015F is based on the same fundamentals of most other capacitor types, that is electric charge separation. An electric field is created when a voltage is applied to the capacitor, which causes the charge to accumulate on the capacitor\'s two electrodes. The magnitude of the field produced is determined by the applied voltage, in addition to the distance between the electrodes and the total capacitance of the capacitor.

When used as a bypass capacitor, the electric field produced by the capacitor helps to reduce the noise and power disturbances associated with high-frequency switching applications. Additionally, the low dielectric losses of the capacitor enable it to store greater amounts of charge, resulting in more consistent voltage levels across the entire capacitor.

When used as a timing capacitor, the MKT1817310015F works by storing charge and releasing it over time in response to the timer input signal. The capacitor stores the charge and then, when the timer triggers the release of the charge, it will induce a voltage across the capacitor. This voltage can then be used to trigger a desired action, such as the triggering of a motor.

Finally, when used as a filtering capacitor, the MKT1817310015F works by providing low impedances for high frequency signals. This allows the capacitor to filter out high-frequency noise and reduce the power disturbances, resulting in a cleaner and more consistent power output.

Conclusion

The MKT1817310015F is a film capacitor that is especially useful for pulse applications. Its application field is very wide, ranging from motor control and standard appliance applications, to high-speed switching power supplies, to telecommunication systems. Additionally, its unique properties, such as its excellent temperature characteristics, low dielectric losses, and high capacitance, make it a highly desirable film capacitor for pulse applications. Furthermore, the working principle of the capacitor is based on the same fundamentals of most other capacitor types, that is electric charge separation.
