Film Capacitors

Film capacitors, also called polyester film capacitors or plastic film capacitors, are electronic capacitors that employ a thin film of plastic as the dielectric material. This type of dielectric material offers very low losses and excellent stability properties over a wide range of temperatures and frequencies.

Film capacitors have several distinct advantages over other types of capacitors, such as ceramic, electrolytic, and tantalum capacitors. They are small in size, they have high insulation resistance, they offer excellent temperature stability, they are non-polarized and have a wide range of working voltages.

DME4S39K-F Application Field and Working Principle

The DME4S39K-F is a film capacitor that is designed for use in a wide range of applications. The voltage range of the device is between 25 to 150VDC, and it can handle currents up to 7 amps. The device has a maximum capacitance of 0.39 microfarads, and it is suitable for use in devices with operating temperatures between -30°C (-22°F) and 85°C (185°F).

The working principle of the DME4S39K-F is fairly simple. It works by storing charge on its two plates, one of which is conducted by an insulated material while the other is insulated. A voltage is then applied to the two sides of the capacitor, creating an electric field between them. This electric field causes electrons to move from one plate to the other, storing energy in the form of electric charge. This stored energy can then be released on demand, depending on the application.

The DME4S39K-F can be used in a variety of applications, such as power supplies, audio applications, and medical equipment. It is also an excellent choice for general purpose AC and DC filtering. The device can also be used to increase pulse discharge current of the power line. Due to its small size, the DME4S39K-F is ideal for space constrained applications.

In summary, the DME4S39K-F is a polyester film capacitor designed for use in a wide range of applications. The device offers excellent temperature stability, low losses, and high insulation resistance, making it an excellent choice for power supplies, audio applications, medical equipment, and general purpose AC and DC filtering.
