Film capacitors are used in a variety of electronic equipment. In general, film capacitors are made of thin films such as polyester, polypropylene, and polyphenylene sulfide (PPS). The main distinguishing feature of film capacitors is that their dielectric material has a special property that allows it to withstand higher electric field strength than an equal volume of a ceramic or electrolytic capacitor.

The WMF2W2K-F application field and working principle make this type of film capacitors ideal for a variety of applications including the switch-mode power supplies (SMPS), power factor correction (PFC), and electronic ballasts. This type of capacitor is also well suited for high frequency DC-DC converters, and high speed fluorescent light dimming applications. The capacitance of the WMF2W2K-F is very low compared to other types of film capacitor, which contributes to the low losses when connected to AC power.

The working principle of the WMF2W2K-F is based on the use of two dielectric layers. The bottom layer is formed by a polyester or polypropylene film, while the top layer is composed of a layer of polyphenylene sulfide (PPS). When a voltage is applied across these two layers, the dipoles of the molecules which form the PPS layer are polarized. This creates an electric field which induces electric charges on the material, leading to the creation of an electric field which results in capacitive coupling between the two layers. This capacitive coupling allows the WMF2W2K-F to store electrical energy in the form of a charge, and release it again when the voltage across the two layers decreases.

The WMF2W2K-F is well suited for a variety of applications due to its low ESR, low ESL, and high dielectric strength. This type of capacitor also has low leakage current compared to other film capacitors, which makes it suitable for applications where low leakage is vital. Additionally, the WMF2W2K-F is a robust capacitor with a high resistance to temperature and humidity, and is reliable even under high temperature and high voltage conditions.

Overall, the WMF2W2K-F application field and working principle make it an ideal choice for many different electronic devices. It is capable of storing a large amount of electricity, and is resistant to temperature and humidity. This makes it an ideal choice for applications where high accuracy and reliability are required. Additionally, its low ESR, low ESL, and high dielectric strength make it well suited for high frequency applications and high voltage applications.
