FilmCapacitors

Film capacitors, also known as plastic film capacitors, are electrical capacitors manufactured from thin plastic films. These films are etched with a pattern that produces a physically and spatially uniform dielectric layer that enables them to offer small sizes with high capacitance and dissipation factor. As such, these capacitors have found widespread applications in industry, including power electronics, lighting systems, LED drivers, industrial control systems, user interfaces, and audio systems. They have become a key component in many high power electronic applications and products.

The MKP18454471041 is an example of a film capacitor that is generally used in high power electronics. It contains a dielectric layer with a thickness of 35 microns between two etched aluminum electrodes, and it has a capacitance of 1.45 mF. The working voltage of MKP18454471041 ranges from 50V to 200V and its high-quality design yields excellent stability even under high voltage stresses. The product also features a high temperature resistance, making it suitable for different types of industrial and commercial applications.

The application field of MKP18454471041 can roughly classified into two categories, namely, AC applications and DC applications. In AC applications, this capacitor is used for applications such as power factor correction (PFC), voltage regulation, and power conversion. In DC applications, it can be used for applications such as battery back-up systems, DC-DC power converters, solid-state relays, motor control circuits, and power inverters. Another important application of this product is its ability to reduce the emission of electromagnetic interference from various electronic devices.

When it comes to the working principle of MKP18454471041, the key is in the dielectric material which separates the two conducting plates from each other. This dielectric material prevents any direct current from passing through, but will allow an alternating current to flow. When a voltage is applied to the capacitor, the alternating current passing through the dielectric builds up a charge on each of the electrodes in proportion to the applied voltage. The ratio of the charge build-up to the applied voltage is the capacitance of the capacitor.

In conclusion, the MKP18454471041 is an ideal capacitor for AC and DC applications in high power electronic products. It offers high capacitance and voltage resistance, making it suitable for a wide range of applications, from medical devices to HVAC systems. Its work principle is based on the ability of the dielectric material to allow a current to pass between two plates without any direct current passing through.
