Film Capacitors

Introduction to 935C4W5K-F

The 935C4W5K-F capacitors are film capacitors produced by AEC-Q200. This series of capacitors can patch up with different external models, and possess high voltage capability, high dielectric and low loss by choosing different encapsulated plastics. They are produced in single, bipolar, or three-line types of different sizes, with several dimensions of 2.8mm*4.5mm, 3.2mm*4.5mm and 3.2mm*6.3mm, etc. Several capacitance selections are available, from 0.4F to 5F.

Applications of 935C4W5K-F

The 935C4W5K-F capacitors are suited for use in all areas where reliable, high-precision and stable performance is required, such as critical decoupling and bypassing, coupling and blocking capacitors and filter capacitors.

In decoupling applications, this series of capacitors are used to deliver high-frequency noise and to reduce voltage generated by electromechanical switch contacts, along with protecting the power supply line againt lightning surge. In bypassing applications, the capacitors enable high frequency noise to pass around the power sources, thus avoiding distortion in the responses. Additionally, they can be used to serve as shields against radio frequency interference, thus eliminating the need for external components in the filter circuit.

In communications filter circuits and video circuits, these capacitors can effectively attenuate noise and EMI, to ensure that wideband signals remain reliable and stable. In automotive applications, these capacitors guarantee the protection of intelligent systems such as chassis electrical systems, braking systems, and media systems from harsh vehicle environment.

Working Principle of 935C4W5K-F

The 935C4W5K-F capacitors function according to the basic principles of capacitance, which is the ability to store electrical energy in an electric field. This series of capacitors are composed of two conducting plates that are insulators sandwiched by a dielectric. A dielectric is a material that can store and release electrical charge, when placed between the two plates. As an electrical charge is applied to one plate, it creates an electric field between the plates; hence, energy is stored in the electric field.

When removing the electrical charge, the process is reversed and the stored energy is released accordingly. The capacitance value determines the stored charge needed to create a voltage potential between the two conducting plates. In the case of the 935C4W5K-F capacitors, the capacitance value is available in a range from 0.4F to 5F, depending on the external model.

Conclusion

The 935C4W5K-F capacitors are versatile film capacitors manufactured by AEC-Q200 standard. This series of capacitors cover different external models, with a range of capacitance value from 0.4F to 5F. They are highly suitable for use in decoupling and bypassing applications, as well as communications filter and video circuits, and automotive systems protection.

The working principle of these capacitors is based on capacitance, which is the ability to store energy in an electric field created between two conducting plates and a dielectric material. When a voltage potential is applied, energy is stored,and vice versa.
