Film capacitors, also known as polymer capacitors, use plastic film as the dielectric medium. Compared to ceramic capacitors and electrolytic capacitors, they have advantages such as small size, large capacitance, low capacity loss, and high insulation resistance. That is why they are often used in various fields, including AC systems, switching power supplies, medical instruments, and high frequency circuits. R60PN3680AA40K is a typical film capacitor, and this article will introduce its application field and working principle.

In the field of AC systems, the dielectric medium of this model generally uses film capacitors with high blocking voltage and wide operation temperature. It is used together with contactors and safety elements to achieve the protection and start of the motor. Bypassing impedances, that is, reducing the start-up current of the motor and suppressing the spike voltage generated when the contactor is turned on are also implemented by film capacitors. Meanwhile, when used in switching power supplies, the film capacitors present high efficiency by reducing the output ripple current and providing voltage isolation. Thanks to film capacitors\' general-purpose characteristic, they can also be applied to medical instruments, energy meters, and other electronic devices. In these applications, R60PN3680AA40K\'s biggest advantage is its resonance free characteristics, as it can reduce distortion, forcing the current of the equipment and the system to be stable during the whole operation process.

Next, let\'s zoom in on the working principle of the R60PN3680AA40K film capacitor. According to the dot structure of PET film material, it is basically composed of two components, namely a linear polarizing agent and repeated ester bonds. When the electric field is applied, the linear polarizing agents in PET film will contain the electric dipole near the space between them, which can truly and completely store charge. To sum up, the working principle of this film capacitor is storing and discharging using electric dipole of linear polarizing agent and dielectric properties.

To conclude, the film capacitor R60PN3680AA40K, which has the advantages of small size, large capacity, and low capacity loss, is widely used in AC systems, switching power supplies, medical instruments, energy meters and many other electronic equipment, thanks to its low capacity loss, large capacitance, and high insulation resistance. According to the dot structure of PET film material and the structure of electric dipole, its working principle is to store and discharge using the linear polarizing agent and dielectric properties.
