Film capacitors, also known as plastic film capacitors, refer to a type of capacitors whose electrodes are embedded in thin plastic films. SFS37S45K375B is a kind of high voltage self-healing film capacitors, suitable for filtering, energy storage, phase shifting, accurate design, etc. It is widely used in power factor correction, energy saving, reactive power compensation, lighting device, switching power supply, air conditioner motor and other products.

In terms of working principle, film capacitors use the electric field generated by the polarization of permittivity of the capacitor film as the working medium, while the electrical energy is stored, released, filtered, and so on. Since the capacitor film has low dielectric loss and small capacitance change with temperature, the film capacitor is superior to other capacitors in terms of frequency characteristics and temperature characteristics. In addition, the film capacitor has the advantage of low ESR, so it can provide excellent ripple current discharge performance, and it also has the self-healing characteristics of gas discharge of non-explosive materials.

SFS37S45K375B film capacitor has large capacity and small volume, which is the most important feature of this product. What\'s more, it is also characterized by high voltage resistance, strong capacitance stability, soft recovery protection function, high breakdown voltage strength, long life and small size. In other words, it can be widely used in many areas like motors, power inverters, power supplies, and so on.

In terms of application field, SFS37S45K375B has wide application in various fields, such as air conditioners, refrigerators, lighting, new energy vehicles, home appliances, power electronics, audio, automotive, UPS, inverters, and so on. For example, it can be used in high-efficiency electric vehicle motor controllers and inverters, high-power variable-frequency speed control for flexible alternating current drives. It can also be used in combination with film capacitors of different specifications for power compensation and energy storage to achieve the purpose of phase compensation and harmonic elimination. It is especially suitable for places such as large industrial and mining enterprises, power grids, and modern buildings where the requirements for power quality are higher.

In conclusion, the SFS37S45K375B high voltage self-healing film capacitor is a kind of high quality capacitor with high voltage resistance, strong capacitance stability, soft recovery protection function, high breakdown voltage strength, long life and small size. It has wide application fields and its working principle mainly relies on electric field generated by the polarization of permittivity of the capacitor film. It is widely used in air conditioners, refrigerators, lighting, new energy vehicles, home appliances, power electronics, audio, automotive, UPS, inverters and other products.
