Film Capacitors

Film capacitors, also called plastic capacitors, have been in production for a long time and have been increasingly popular due to their low cost and even lower electronic noise characteristics. The most common type of film capacitor is the DME4W1P2K-F, which is suitable for a wide range of applications.

Application Fields of DME4W1P2K-F

The DME4W1P2K-F can be used in a wide range of industries, including consumer electronics, robotics, industry automation, and medical technology. It is suitable for applications requiring low currents or pressures, including switching power supplies, switching circuits, noise suppression, and filtering multiple levels. It can also be used in high-voltage power distribution, motor drives, safety circuit switches, and anti-surge or noise suppression.

Working Principle

The DME4W1P2K-F is a metallized polyester film capacitor with a non-inductively wound metallized polyester dielectric core. The low-voltage model of the DME4W1P2K-F is a non-electrolytic capacitor, which means that it does not use a polarizing agent, such as electrolyte, in order to operate. It is made of a conductive, wound metallized film dielectric core which is covered by a plastic case. It is a non-electrolytic capacitor meaning that it does not use polarizing agents, such as electrolyte, in order to operate. The dielectric core is made of the same film as a metallized polyester film capacitor, which is covered by a non-conductive plastic case. As a result, the DME4W1P2K-F is highly resistant to moisture, heat, and vibration.

The DME4W1P2K-F is composed of two positive terminals and a negative one. When an electric charge is placed across the terminals of the capacitor, an electric field is created. This electric field then creates a dielectric force between the positive and negative terminals, which allows for the storage of energy in the form of an electric field. As the capacitor is charged, the stored electric field increases. When the applied voltage is removed, the capacitor will then begin to discharge, releasing the stored energy in the form of an electric current.

The DME4W1P2K-F has excellent electrical characteristics, such as low ESR (Equivalent Series Resistance), low self-heating, high accuracy, and low capacitance tolerance. The low values of ESR and self-heating minimise losses of electric power and maximize the energy storage capabilities of the capacitor, and the higher accuracy allows for greater power production. The main advantage of the DME4W1P2K-F is its non-inductive winding, which allows for a high degree of shielding both from external and internal magnetic fields. This helps to reduce the risk of magnetically induced interference in electrical equipment and can significantly increase the lifespan.

Conclusion

Overall, the DME4W1P2K-F is a highly versatile and reliable film capacitor. It is suitable for a wide range of operations ranging from low current applications to high voltage power distribution. Its non-inductively wound dielectric core and low values of ESR and self-heating makes it ideal for use in high accuracy systems and electric power production. The DME4W1P2K-F is an ideal choice for applications needing low-voltage power, and its shielding capabilities make it a great choice for electronic equipment that needs to be protected from magnetically induced interference.
