Film capacitors, also known as plastic film capacitors, are composed of two metal electrodes and a dielectric film. The dielectric film usually comprises polyester (Mylar or PET), polypropylene (PP), polycarbonate (PC) or polystyrene (PS). Film capacitors are available in a number of types –35ST155M3225 is one of them. It is mainly used in applications where high energy density, high capacitance in a small package, long operational life and good temperature stability is required.

In order to understand 35ST155M3225 better, let’s take a look at its application field and working principle.

Application field of 35ST155M3225

The main application of 35ST155M3225 is to filter noise. It provides superior parallel stability and minimizing ringing voltage phenomenon in applications where fast switching or edge rate rise time is essential. 35ST155M3225 is also widely used in many audio and broadcasting applications, because it is able to reduce magnetic and dielectric interference. Additionally, because of its low cost and small size, it can be used as electronic noise suppressorship in all fields.

Working Principle of 35ST155M3225

35ST155M3225 film capacitors mainly work by storing electrical energy in an electrostatic field. The principle of the film capacitor is to use an insulating material as a dielectric, which is also called the film. An electric field is generated between two metal electrodes when a voltage is applied. The electric field created between the electrodes forms an electrical barrier, allowing the capacitor to store energy.

When voltage is applied to the electrodes, charge accumulates on the plates and creates an electrical field between them. The dielectric material placed between the electrodes prevents the charge from discharging, allowing energy to be stored in the electric field. Once the voltage is removed, the stored electric charges can be discharged, resulting an a capacitive electronic component.

Conclusion

To sum up, 35ST155M3225 film capacitors are widely used in noise filtration, audio and broadcasting applications, and can also be used as electronic noise suppressors. Its main working principle is to store electrical energy in an electrostatic field by generating an electric field between two metal electrodes, with a dielectric material as the barrier to prevent the charge from discharging.
