Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of capacitor that uses a dielectric medium made from plastic film (such as polyester, polypropylene, polyethylene, or other similar materials). They are widely used in various applications, such as AC motor run capacitors, line bypass capacitors, and EMI suppression filtering.Of these, the MKP18423684000 is a film capacitor specifically designed for AC motor run applications. It features a capacitance range of 0.1-472 µF and a voltage rating of 630 VAC (50/60Hz). The capacitor has a bending radius of 15-20 mm, and a maximum operating temperature of 70 ℃.The working principle of film capacitors is relatively simple. When a voltage is applied, an electric field is generated and causes the dielectric to polarize. This polarization creates a force which attract the two plates together, creating the capacitance. This phenomenon is known as dielectric absorption. The dielectric absorption also helps to minimize leakage current and maintain the capacitance over time, leading to reliable performance.

Construction

The MKP18423684000 is a self-healing, PCB-mountable, radial-lead film capacitor. It consists of two metal discs that are thermo-welded together and then vacuum impregnated with the dielectric material. The capacitor is then encased in a plastic or vinyl shell and the leads are connected to the terminal discs.The construction of the MKP18423684000 film capacitor is designed to provide long life and reliable performance. The dielectric material is specifically chosen to provide high insulation resistance and low losses, ensuring a low temperature rise and low ESR. Furthermore, the self-healing properties of the material mean that minor shorts due to particles, contaminants, or other environmental factors have no lasting effect on the capacitance or performance of the part.

Applications

Film capacitors are widely used in a variety of applications, ranging from motor run capacitors to filter and bypass capacitors. The MKP18423684000 is specifically designed for use in AC motor run applications. Motor run capacitors are used to help motors run more efficiently, and help to reduce start-up time and stabilize current.
