A film capacitor or film dielectric capacitor, is a capacitor that uses a thin plastic film as its dielectric insulation. One of the most commonly used film capacitors is the SFT44S35K303B-F. It is primarily used in general circuitry, as it provides a reliable way of filtering and attenuation in electric and electronic systems. In this article we will look at the application fields of the SFT44S35K303B-F and its working principle.

Types of Film Capacitors

Film capacitors are broadly classified either into metallized film capacitors or film paper capacitors. Metallized film capacitors employ a thin film of polyester or polypropylene as its dielectric. Two metal electrodes are applied to the surface of the dielectric film to constitute the capacitor. On the other hand, film paper capacitors employ a paper or kraft paper as its dielectric material, and incorporate two metal foils or three metal electrodes in one structure.

The SFT44S35K303B-F Application Field

The SFT44S35K303B-F is a film capacitor that is well-suitable for motor control applications, audio noise suppression, voltage stabilization, coupling, bypassing, decoupling and off-line power supply filtering applications. It can also be used in power amplifiers, DC/AC converters, switch-mode power supplies, actuators, appliance motors and other general circuitry applications. The SFT44S35K303B-F has a dielectric material of polypropylene film. It has an operating temperature range of -40℃ to 85°C and a rated voltage of 250V with a capacity of 0.47μF. It has high insulation resistance and low dissipation factor.

SFT44S35K303B-F Working Principle

The most important feature of film capacitors is that, they are able to achieve high effect in reducing the noise level. The SFT44S35K303B-F works by acting as a low-inductance filter that can respond rapidly to voltage changes in an electrical system. When the operating voltage is applied to the terminals of the capacitor, charges will be stored and the capacitor’s state of charge will be changed. The SFT44S35K303B-F film capacitor will perform its filtering and attenuation functions by acting as a kind of buffer between the source and the output. Thus, any sudden voltage changes will be suppressed, thus reducing the amount of high-frequency noise.

Conclusion

The SFT44S35K303B-F is a film capacitor that can be deployed in a wide range of general circuitry applications, from motor control to audio noise suppression. Its long life performance and low-inductance feature make it an ideal choice for general circuitry. The working principle of the SFT44S35K303B-F involves dissipating unwanted noise and microwave interference. With its high insulation resistance and low dissipation factor, the SFT44S35K303B-F is a reliable, and cost-efficient choice for film capacitors.
