Film capacitors can be used in a variety of applications, such as radio frequency (RF) and audio applications, due to their low loss, high pulse and voltage capabilities, and reliability. The WMF2S15K is a type of film capacitor specifically designed for a variety of DC applications.

The WMF2S15K has a temperature coefficient of ± 0.03 %/°C, which makes it ideal for applications requiring stability over a wide temperature range. It is also highly reliable due to its superior dielectric stability, low ESR (Equivalent Series Resistance) and high insulation resistance. The external construction of the WMF2S15K has a separated winding instead of being a solid steel core, which allows the end user to adjust the capacitance to fit the application they require it for.

The primary purpose of a WMF2S15K is to limit the start-up current of a DC application, such as a DC motor or solenoid, and to filter or reduce electrical noise. It can also be used to smooth out small peaks in the current flow and reduce harmonic distortion in a power circuit. Additionally, the WMF2S15K can be used in DC filter applications, such as eliminating interference from nearby RF transmitters.

The working principle of the WMF2S15K is based on the phenomenon of dielectric polarization, which is the ability of a material to become electrically charged in an electric field. When an electric field is applied to the WMF2S15K, the electric flux lines will be generated between the two electrodes. This will cause the dielectric material to be polarized, producing a capacitance between the two electrodes.

The capacitance of the WMF2S15K can be adjusted by changing the size and geometry of the dielectric material. This is done by winding the capacitor with different wire sizes and configurations. For example, when the wire is wound in a tighter configuration, the capacitance will increase. Conversely, when the wire is wound in a looser configuration, the capacitance will decrease. The capacitance of the WMF2S15K can also be adjusted by using different dielectric materials with different permittivity values.

The WMF2S15K is a highly reliable capacitor and is suitable for a variety of DC applications. Its versatile design makes it a great choice for applications that require a stable capacitance over a wide temperature range. In addition, its adjustable capacitance allows for precise tuning of the circuit as required.
