Capacitors are widely used in electronics circuits. Film Capacitors is one of the most common type of capacitors. They are composed of two conducting plates separated by an insulator (dielectric), which is made from plastic film. The SFT44S60K475B film capacitor, manufactured by Stackpole Electronics, Inc., belongs to this family. This capacitor has a capacitance of 0.47μF, an operating temperature range of -55 °C to +125 °C, and a voltage rating of 600V. In this article, we will discuss the application fields and working principle of this film capacitor.

Working Principle

The SFT44S60K475B film capacitor works in the same way as other types of capacitors. It works by using the electric field generated between the two parallel conductive plates. When a voltage is applied across the two plates, the electric field acts as an insulator, preventing the charge from flowing between the two plates. This means that the capacitor acts as a store of electric charge. As the voltage applied to the plates increases, the voltage across the capacitor increases, and so does the amount of charge stored by the capacitor.

The SFT44S60K475B film capacitor, in particular, uses a Mylar dielectric film made of polyester. The Mylar film is capable of operating in a wide temperature range and has excellent stability over time and with frequency changes. Its large area of exposure between the two conductive plates also ensures high capacitance values.

Conclusion

The SFT44S60K475B film capacitor is a common type of capacitor that finds its application in a wide range of consumer and industrial products. It works by storing charge between two parallel conductive plates, using a Mylar dielectric film. Its high capacitance values, temperature range and frequency stability make it suitable for a variety of applications.
