Q: What is the main application of film capacitors?

A: In the next few years, with the further development of digitalization, informatization, and network construction, and the increased investment in power grid construction, electrified railway construction, energy-saving lighting, hybrid vehicles, etc., as well as the upgrade of consumer electronic products, the market demand for film capacitors will show a trend of rapid growth. With the development of technology level, the replacement cycle of electronics, home appliances, communications and other industries is getting shorter and shorter, and film capacitors have become an indispensable electronic component to promote the replacement of the above industries with their good electrical performance and high reliability.

Q: How capacitors eliminate high-frequency noise?

A: For high-frequency bypass capacitors, since the higher the frequency, the lower the impedance, the greater the current flowing through the capacitor for high-frequency noise.

The bypass capacitor is equivalent to a small resistor for high-frequency noise, which consumes the high-frequency noise, thereby reducing the impact of high-frequency noise on the circuit.
