Film Capacitors

Film capacitors are generally electrochemical capacitors with electrolytes made of organic electrolytes or plastic films. The development of metalized film capacitors has taken polymer capacitors to a new level of performance. The metalized film capacitors have superior electrical performance and a much wider range of temperature and frequency ratings. The rated capacitance range is also very large, from fractions of a picofarad to thousands of microfarads.

ECW-F4274HL application field and working principle

ECW-F4274HL is a metalized film capacitor, using high-grade imported raw materials, under the premise of meeting the requirements of safety and environmental protection, and using advanced production equipment to improve the safety and reliability of the product. ECW-F4274HL is widely used in the fields of communications, medical equipment, video, audio, instrumentation, lighting and IT. Its working principle is that the two metal electrodes of the capacitor are connected to the outside and connected to the AC power supply in series. When the power supply is output, an electric field is generated between the two metal electrodes. The electrostatic effect allows the electric field to penetrate the metalized film insulation, forming an electrical bridge between the two electrodes to enable the electric current to flow.

ECW-F4274HL belongs to the film type capacitor, which has different characteristics from other types of capacitors, such as high insulation resistance, wide working temperature range, and wide capacitance range. It can maintain stable electrical performance under various frequencies, is not easily affected by temperature, and is suitable for working in high temperature and high humidity environments. Its low equivalent series resistance makes it a good choice for high-frequency devices, full frequency range for audio and high noise immunity for digital applications.

In addition, the metalized film capacitor has the advantages of low cost and waterproof performance. Its electrical parameters and chemical properties are stable. The most important point is that the metalized film capacitor can improve the reliability and increase the lifespan of the capacitor.

In conclusion, the metalized film capacitor ECW-F4274HL is widely used in various fields, and its excellent electrical performance and reliable safety make it a good choice.
