Film Capacitors
• 171104K160E-F Application Field & Working Principle
  • Application Field
    • The 171104K160E-F is a general purpose film capacitors that can be applied in most AC and pulse circuits. It uses Polyester Metallized Film as the dielectric. It is suitable for the power supply, high frequency transformer, voltage regulator, automotive electronics, etc.
    • In the power supply circuits, this type of capacitor can be employed to filter and store energy. It can reduce the source ripple voltage and suppress electric spark caused by switching, which further improves the power quality of the system.
    • In the high frequency transformer, the 171104K160E-F capacitor has a wide operation frequency range and can keep the electric force balance in the transformer. It helps to reduce the magnetic leakage and improve the working efficiency.
    • In the voltage regulator, it can maintain a constant voltage over the AC frequency thus ensuring a sound operation for the connected load.
    • It also has its application in other areas such as automotive electronics, transportation equipment, air conditioner, medical equipment, etc.
  
  
  • Working Principle
    • The film capacitor is made of two or more sheets of metalized polyester film or other dielectric material with flat surface. The layers of metalized film are bonded together with an insulating material. An external metal casing encloses the whole assembly.
    • The principle of the film capacitor is to store energy, which is generated by the space between two electrodes. When an AC voltage is applied to the capacitor, the electric field created by the voltage causes a displacement current to flow between the two electrodes. Depending on how much the poles are close, the size of the electric field and the displacement current will change.
    • The stored energy of the film capacitor can be used to maintain a steady voltage in circuits, filter out the unwanted noise, or to supply power to the devices quickly during high current mutations. Besides, film capacitors also have the advantage of having a larger temperature stability, higher dielectric strength and better design flexibility.
