Film Capacitors: MKT1817333254D application field and working principle

Film capacitors are a type of capacitor that has evolved significantly over the years. Initially, film capacitors were used as simple smoothing capacitors as part of a low pass filter, for which two metal plates were connected and separated from one another by a dielectric material such as mica. More recently, polymide/glass, polymide/metal, and polymide/ceramic films have been developed, allowing for greatly enhanced dielectric constants, stability, and overall performance.The MKT1817333254D is a high value low voltage film capacitor. It is rated for 85°C and has self-healing properties. It is suitable for use in power supplies, as well as in various other applications where a small size and low cost are required.The MKT1817333254D film capacitor is an axial-leaded metallized polyester film capacitor. It is available in a variety of capacitance values ranging from 10 to 4700 pF and voltage ratings from 6.3 V to 275 V. The product also features an epoxy-encapsulated metalized termination for improved long-term mechanical stability.This capacitor is usually used for applications where the primary concern is about the size of the capacitor and a relatively low price. Examples include power supplies, audio applications, high frequency electronics, and many others.The MKT1817333254D film capacitor works on the principle of dielectric absorption. A dielectric material is placed between two conducting plates, or electrodes, when the capacitor is connected to a voltage source. The dielectric material forms an electrical barrier between the two terminals and creates an electric double layer. This double layer stores electric charge and the capacitor can be considered a storage device for electrical energy.The MKT1817333254D film capacitor also features a self-healing mechanism. When the capacitor is subjected to a short-term over voltage, a conductive path is created between the two electrodes. During this process, a small spark discharge takes place and the conductive path is broken, resulting in the capacitor passively resisting any further voltage spikes.The MKT1817333254D has a wide variety of applications due to its low cost, small size, and excellent performance. It is often used in power supplies, high frequency electronics, and in audio applications. It can also be used in various low voltage and low power circuits. The high capacitance values of the MKT1817333254D make it an ideal choice for smoothing and supplying power in a wide variety of applications.In conclusion, the MKT1817333254D is a low voltage, low cost film capacitor that is ideal for use in power supplies, audio applications, high frequency electronics, and in various other applications. It works on the principle of dielectric absorption and features a self-healing mechanism for protection against short-term overvoltage. The high capacitance values and excellent performance make the MKT1817333254D an ideal choice for a wide variety of applications.
