Film Capacitors
Film capacitors are one of the globe’s most widely used type of passive components due to their many advantageous properties such as: simple construction, low parasitics, high volumetric efficiency, a wide range of values, high reliability, and a long life.The 223MWR102K is a film capacitor that is well suited for a variety of applications due to its diverse range of characteristics. This capacitor is non-polarized, offers a low ESR, high operating temperature (155°C), voltage rating up to 630V, and temperature coefficient of capacitance of -22%.In terms of its application field, the 223MWR102K is ideal for motor run and DC link applications including uninterruptible power supply systems, digital recorders, inverters, lighting power, converters, switch-mode power supplies, and power controllers. The 223MWR102K additionally has several features and benefits which make it a useful device for various applications. This capacitor is self-healing, that is, it self-recovers from any short circuit or electrical breakdown that may occur. Additionally, this type of capacitor maintains its characteristics, despite having a long life, and therefore performs well in extreme environments.Regarding the working principle of the 223MWR102K, it is composed of alternating layers of metalized polyester or polypropylene film, an encapsulated dielectric fluid, and an impregnant, typically based on silicone oils. The metalized film is built up of thin layers of aluminum deposition, while the impregnant and dielectric fluid are a combination of oil and wax, and possibly some additives. This combination of film, dielectric fluid, and impregnant creates the dielectric field that produces the capacitor’s capacity. When current is applied, the aluminum layers will create a metal deposition barrier, forming a metal-oxide-semiconductor layer. This MOS layer allows for the transfer of current to occur. The 223MWR102K uses the eurlicht effect, which is the process of creating an electric filed and thereby causing an uneven distribution of charge inside an oxide film. This effect occurs when a reverse voltage is applied, creating a depletion layer within an oxide and thus increasing the capacitance of the film capacitor.In conclusion, the film capacitor, as exemplified with the 223MWR102K, is characterized by its high volumetric efficiency, wide range of values, high reliability, and long life, making it an ideal choice for many motor run and DC link applications. Its features and benefits contribute to its popularity among electronic components, and its working principle, utilizing the eurlicht effect and other processes, explains basis for its many features.
