Film Capacitors

Film capacitors are capacitors that use film as a dielectric medium. They are widely used in AC power line filters, high frequency communication, and other applications. The MKP1840347405M is a type of film capacitor designed for these applications.

Construction

The MKP1840347405M is a polypropylene dielectric film capacitor. It has two aluminum foil electrodes that are encapsulated in a cylindrical plastic case. The plastic case is then hermetically sealed to prevent oxidation, dust, or moisture from damaging the capacitor. The interior of the capacitor is filled with a dielectric oil, which helps to reduce the effect of extreme temperatures on the capacitor.

Performance

The MKP1840347405M has a voltage rating of 500 V and a capacitance range of 0.1µF to 1µF. It has a wide operating temperature range of -55°C to +125°C and a long lifetime of up to 10,000 hours. It is also highly resistant to shock, vibration, and moisture.

Application Field and Working Principle

Film capacitors are used in a variety of applications, such as AC filtering, surge suppression, high frequency communication, and signal filtering. The MKP1840347405M can be used in all of these applications.The working principle of film capacitors is fairly simple. The two aluminum foil electrodes act as plates, and the dielectric material between them creates an electric field that stores charge. When a voltage is applied to the terminals of the capacitor, the electric field stores charge and the capacitor provides capacitance. This is how film capacitors are able to filter out AC noise in power lines, suppress spikes, and filter out high frequency signals.

Advantages

Film capacitors have a few benefits compared to other types of capacitors. They have better insulation properties, a wide temperature range, and long lifetimes. They are also highly reliable and resistant to shock and vibration. Furthermore, they are much smaller and lighter, making them ideal for portable devices and applications where space is an issue.

Conclusion

The MKP1840347405M is a type of film capacitor designed for a wide variety of AC and high frequency applications. It has a wide capacitance range, long lifetime, and high reliability. It is also very small and lightweight, making it suitable for portable devices or applications with space constraints.
