Film Capacitors

103MWR400K Application Field and Working Principle

103MWR400K is a type of film capacitor that belongs to the family of dielectric capacitors. It is especially made to meet the requirements of high performance materials. This type of capacitor has excellent electrical properties which makes it suitable for a wide range of applications. To gain further information on this product, it is essential to understand its application field and working principle.

Application Field

Film capacitors are used in various applications of televisions, computers, mobile phones, medical equipment and more. 103MWR400K features a wide temperature range and low ESR (Equivalent Series Resistance), high capacitance stability, high ripple current capability and high insulation resistivity. These properties make 103MWR400K a great option for applications that require reliable operation even in extreme environments or high temperature and vibration. 103MWR400K is used most often in products requiring high power levels and robust construction such as UPS power stages, DC link circuits and some power converters used in industrial automation control.

Working Principle

103MWR400K is a capacitor composed of two metallic plates separated by a dielectric material or medium. In this case, the dielectric material is a high grade film that has been processed and cut into small pieces before being wound together and treated for the desired performance. When a voltage is applied to the two plates, the alternating electric field created by the voltage produces an electric force that moves charges from one plate to the other. This produces a charge differential that stores energy in the form of an electric field between the two plates. When the voltage is removed, the stored charge is maintained in the capacitor and discharged gradually over time.

103MWR400K has several advantages over other, more conventional types of capacitors. The dielectric film provides better electrical performance due to the extremely low self-inductance it offers, while the short circuits inherent within metal-oxide capacitors are entirely eliminated due to the absence of metallic parts. As a result, these capacitors have a better life span and can handle much higher voltage levels, making them suitable for a variety of applications.

Conclusion

103MWR400K is a type of film capacitor that is designed and manufactured to meet the stringent requirements of high performance materials. It has excellent electrical properties, making it suitable for applications that require reliable operation even in extreme environments or high temperature and vibration. 103MWR400K is composed of two metallic plates separated by a dielectric material or medium, and when a voltage is applied to the two plates, an electric force moves charges from one plate to the other, producing a charge differential that stores energy in the form of an electric field between the two plates. Its advantages over other, more conventional types of capacitors include better electrical performance, a better life span and the ability to handle much higher voltage levels.
