Film capacitors, also known as polyester, polypropylene or polycarbonate capacitors, are a type of capacitor that uses a thin plastic film as a dielectric material. The film is typically wound into a cylindrical or flat shape and provides a large capacitance for a given volume. They are often used in power, audio and automotive applications, as well as general purpose electronic circuits.

The WMF2P1K-F is a type of film capacitor specifically designed for power applications such as motor drives, switching power supplies and other applications. It has been designed to reduce the self-resonance frequency compared to other types, allowing it to switch further at high frequencies while also reducing noise generation.

The film used in the WMF2P1K-F is a polyester film with a dielectric constant of 6.1. This provides a significant improvement in electrical performance over other types of capacitors with a lower dielectric constant. The construction of the capacitor utilizes layers of aluminum foil and polyester film to provide a reliable, low-resistance connection. It has been designed to withstand high voltage spikes and is capable of handling a maximum working voltage of 1KV.

The working principle of the WMF2P1K-F is the same as for any other film capacitor. The thin film is placed between two conducting surfaces, one of which is the capacitor\'s terminal. A voltage is applied across the terminals and a capacitive current is generated. The electrons from the applying voltage will be repelled from the positive charge of the capacitor\'s terminal and will flow around the film\'s edges and back to the negative plate. This allows the current to be stored in the form of a charge and is known as the electrical field.

The WMF2P1K-F also features an overcurrent protection feature. This is achieved by using a series of resistors between the capacitor\'s terminals and the fuse. If the current through the capacitor becomes too high the fuse will blow, cutting off the current and preventing any further damage to the capacitor.

The WMF2P1K-F is a reliable and robust film capacitor that is suitable for use in a variety of power applications. It offers excellent electrical properties and is capable of withstanding high voltage spikes and is also protected from over-current by the built-in fuse. This makes it a great choice for use in power supplies, motor drives and other high power applications.
