Film Capacitors

Film capacitors are non-polarized energy-carrying components in electric circuits. The variant of film capacitor is identified by its application field and working principle. One example is 935C1W3K-F.

Application Fields of 935C1W3K-F

The 935C1W3K-F is a polypropylene film capacitor designed to be used in a wide range of temperature. It is an ideal capacitor for high-voltage applications and for electric motor control. It is also suitable for use in aircraft lines and commercial lines. Moreover, it provides perfect insulation for double-layer capacitors and is widely applied in the filtering and coupling of audio amplifiers. With a DC voltage rating up to 5,000V and a peak voltage rating up to 10,000V, the 935C1W3K-F provides outstanding performance and stability.

Working Principle of 935C1W3K-F

The working principle of 935C1W3K-F relies on the properties of the capacitor. The capacitor consists of two conductive metal plates that are separated by an insulating material. In the case of 935C1W3K-F, the metal plates are covered with a polypropylene film which serves as the insulating material. When an electrical voltage is applied across the metal plates, an electrical field is created, which attract the electrons to one of the plates. This process results in a potential difference between the plates, thus creating a capacitance. The capacitance of the capacitor is dependent on the size of the plates, the distance between the plates and the type of insulating material.

Advantages of 935C1W3K-F

In comparison to other Film Capacitors, the 935C1W3K-F is known for its outstanding durability and long-term stability even when exposed to extreme temperatures, as it is able to withstand temperatures up to -55℃ to +105 ℃. It is also resistant to moisture, corroding and have a low dielectric absorption compared to metalized polyester film capacitors.

Disadvantages of 935C1W3K-F

However, 935C1W3K-F is relatively costly and the disposal of this capacitor can be more complex due to the nature of their insulating material. Further, the working principle of the 935C1W3K-F is solely based on the property of the capacitor, making it a single-use device.

Conclusion

In conclusion, the 935C1W3K-F is a polypropylene film capacitor designed with outstanding performance and durability. It is a good choice for high voltage applications and electric motor control due to its high DC and peak voltage ratings. Although its disposal process may be complex, 935C1W3K-F is one of the best options when it comes to Film Capacitors.
