Film capacitors, also called plastic film capacitors, are electrical components manufactured using thin plastic films as the dielectric. These are widely used in electronic circuits due to their high performance, relative low cost, and long life. WMF4D47K is one of the most popular film capacitor types, owing to its excellent performance, reliable operation, and large capacitance.

WMF4D47K capacitors are surface-mount devices used for various applications such as filtering, bypassing, and coupling in power grids, energy systems, and electronic circuits. The capacitors are designed to protect various electrical components from damage during normal operation and are also known to provide consistent capacitance and voltage performance. They consist of a dielectric layer, a lead frame, and two metal electrodes, and their construction is tailored to meet the required operational conditions. The capacitors feature two small mounting pads or release tabs that allow it to be easily mounted onto most printed circuit boards. The capacitors also feature high dielectric strength, high capacitance stability, and improved temperature stability, all of which make them an ideal choice for a variety of applications.

The working principle of WMF4D47K capacitors is quite simple. The capacitors have two metal electrodes that are separated from each other by a dielectric material. When a DC voltage is applied to the two electrodes, an electric field is generated between them, which results in the electrons in the electrode material being rearranged. This rearrangement of electrons creates an electric field between the electrodes, which is called the “capacitance”. Since the capacitance is proportional to the area of the electrodes, the capacitance of the WMF4D47K is directly related to the surface area of the electrodes. Consequently, the higher the capacitance of the capacitor, the higher the surface area. This means that the higher the voltage applied to a WMF4D47K capacitor, the higher its capacitance, which is why these capacitors are ideal for high voltage applications.

Overall, WMF4D47K capacitors are well-suited for numerous applications, such as paperless and paper capacitors, miniaturized chargers, high voltage power supplies, and more. Their excellent performance, reliable operation, and large capacitance make them a popular choice for many designers and engineers. Despite their widespread use, manufacturers are continuously researching new application areas and improving their performance.
