Film Capacitors

Film capacitors, also known as film dielectric capacitors, are one of the oldest types of capacitors invented and developed and are still used widely today. Compared to ceramic capacitors, film capacitors are known for their superior performance and durability, making them the preferred choice for certain applications. They are classified into two main categories – fixed and variable – where the fixed film capacitors utilise an insulating layer (known as the dielectric) made up of a thin plastic film, while the variable film capacitors contain several layers of plastic film as well as a conducting element between them.The MKP385420125JI02W0 is a type of film capacitor, specifically a radial-lead appliance class X2 capacitor. It has an operating temperature range of -40 to +85 Celsius. The MKP385420125JI02W0 has a dielectric of metalized polyester film, with a tantalum voltage compensation element. It has a 5mm maximum diameter and a lead pitch of 12.5mm, making it a suitable choice for various low-power applications.The applications of MKP385420125JI02W0 primarily include use in various consumer electronics. Due to its small size, the MKP385420125JI02W0 is ideal for use in mobile devices, computers, televisions and other low-power devices. It is also used as a thesaurus and for signal filtering in various circuit designs. Additionally, it can be used for power-supply decoupling, and for suppressing interference caused by different electrical components. Now, let us discuss the working principle of the MKP385420125JI02W0. The inner core of the capacitor is made up of metalized polyester film. This film serves as the dielectric that insulates the two plates from each other. The voltage compensation element functions as the second plate, being electrically connected to the positive and negative sides of the capacitor. When a voltage is applied to the capacitor, it causes the voltage compensation element to move towards the outer side of the capacitor and creates an electric field between the two plates. As a result, a small electric charge is stored in the capacitor, which is then discharged when the voltage is removed. The stored electric charge can then be used in various applications, such as providing power to an LED or powering a speaker. In summary, the MKP385420125JI02W0 is a type of film capacitor designed for low-power applications. It is ideal for use in mobile devices, computers, televisions and other low-power devices, as well as for signal filtering and power-supply decoupling in various circuit designs. The MKP385420125JI02W0 works by using an insulating layer made up of metalized polyester film, with a tantalum voltage compensation element to create an electric field between the two plates when a voltage is applied, thus storing an electric charge.
