Film capacitors, also known as film dielectric capacitors, polyester capacitors, plastic capacitors or PET film capacitors, are passive electronic components which store energy in an electric field between two metal electrodes through a “dielectric” film of polyethylene naphthalate (PEN).

WMC2S68K-F is an example of a PEN film capacitor manufactured by Soshin Electric. It is a polypropylene (PP) film capacitor in an axial radial package (1 EIA-sized case, 5mm diameter).The WMC2S68K-F is designed to provide a broad range of performance characteristics such as low ESR, low DC bias, high capacitance, and low leakage current.

The WMC2S68K-F is typically used in a variety of applications such as motor control, switching power supplies, and motor control. It can be used in applications which require a low ESR and high capacitance, such as snubber circuits, AC line filters, and power supply filters. It can also be used in other applications which require low DC bias, such as high-frequency signal processing, telecommunications, and DC blocking. The WMC2S68K-F is also a suitable for high-voltage applications, such as medical equipment, motor applications, and appliance motors.

The working principle of a film capacitor is based on the standard capacitor equation that states that the capacitance of a capacitor is inversely proportional to the distance between the plates. The plates of a film capacitor are made of an incredibly thin film of plastic, such as PEN or PP (or a combination of both). This plastic film acts as the dielectric, enabling it to store a high amount of charge in a small area. The charge is stored in the form of an electric field, which is created when electrons are drawn away from the thin film and attracted to the metal plates.

The key features of a film capacitor are its high capacitance, long life, and stability over a wide range of temperatures and frequencies. The tightly-stacked layers of polyester film helps to minimize dielectric losses, resulting in low electrical losses and a high electrical insulation resistance. Furthermore, film capacitors are also resistant to vibration, shock, and humidity, as well as being highly stable in terms of their capacitance, meaning that they provide consistent performance and reliability.

The WMC2S68K-F is an ideal choice for applications requiring a low ESR and high capacitance. It is also suitable for use in a variety of applications such as motor control, AC line filters, power supply filters, and high-frequency signal processing. Additionally, the WMC2S68K-F is designed with a low DC bias, enabling it to provide stable performance over a wide range of temperatures and frequencies. All of these features make the WMC2S68K-F an effective and reliable choice for a variety of applications.
