Film Capacitors

Film capacitors, also known as plastic dielectric capacitors, are capacitors with plastic film on its electrode plates as the dielectric material. The BFC238670274 is an example of such plastic film capacitor. The device offers a wide range of features and advantages that make it a great choice for high-power applications. In this article, we will take a closer look at the application field and working principle of the BFC 238670274.

Application Field of the BFC 238670274

The BFC 238670274 film capacitor is designed primarily for applications where high-power capability is required. It is extremely reliable due to the dielectric strength of the plastic film. This capacitor has a high working temperature range of -40°C to + 65°C, and a very low internal resistance which makes it suitable for handling high currents. The device’s excellent frequency response also makes it suitable for use in modern electronic equipment. It has been used extensively in switch mode power supplies, motors, PLCs, frequency converters, UPSs, and other industrial control systems.

Working Principle of the BFC 238670274

The BFC 238670274 uses a plastic film as the dielectric material. As the voltage across the electrodes increases, a current flow occurs between the electrodes. This current is reinforced as a field is created within the dielectric material of the capacitor and additional charge is accumulated on the surface of the electrode plates. The higher the voltage between the two plates, the stronger the field created by the conductor, and the dielectric material, causing the capacitance of the BFC 238670274 to increase. The capacitance of the BFC 238670274 is also affected by its temperature. As the temperature increases, the capacitance will decrease. The temperature coefficient of the capacitance is -0.2%/°C. This ensures that the BFC 238670274 is not affected by extreme temperatures, as the capacitance will remain largely unchanged within the desired temperature range.

Conclusion

The BFC 238670274 plastic film capacitor is a highly reliable device for high-power applications. Its high working temperature range and low internal resistance make it ideal for applications that require high current handling capabilities. Its excellent frequency response also makes it suitable for modern electronic equipment. In summary, the BFC 238670274 is an excellent choice for various high-power applications, such as switch mode power supplies, motors, PLCs, frequency converters, and UPSs.
