Film Capacitors

Film capacitors are components used in many different electrical and electronic circuits. They are versatile, reliable, and durable components that are available in a wide range of sizes and forms. One of the types of film capacitor is the WMF1S47K. This type of film capacitor is specially designed with a unique backing film and offers a number of advantages and unique properties when compared to traditional film capacitors.

Application Field

The WMF1S47K is specifically designed for high frequency applications where good phase stability, low ESR, and low self- inductance are required. It is typically used in power supplies, motor control, audio, and radio frequency applications. Furthermore, the low ESR of the WMF1S47K makes it ideal for use in mobile and high-bandwidth applications, such as radio transceivers and base stations. Additionally, its ability to perform in harsh or high-temperature environments makes it suitable for use in automotive, military, and medical applications.

Working Principle

The WMF1S47K uses a unique backing film which is constructed using metallized PET (polyethylene terephthalate) material with multiple layers of film. This allows for the creation of many layers of capacitance which are insulated from one another. As a result, capacitance density and stability are improved, while ESR and inductance are reduced. Additionally, this backing film also helps to improve and maintain high-frequency performance. It also offers superior thermal stability, making it suitable for use in high temperature environments.

The WMF1S47K also features a dielectric which allows for greater capacitance in a smaller volume, as well as better resistance to moisture and humidity. Additionally, its metalized terminals also reduce contact resistance and help to reduce insertion loss. Furthermore, natural convection of the case helps protect the capacitor from damage.

The WMF1S47K is a high-performance film capacitor which is well-suited for high-frequency and high-temperature applications. With its unique backing film, low ESR, and high-frequency performance, it is an excellent choice for a wide range of applications.
