Film Capacitors

Film capacitors are a type of capacitor manufactured with dielectric films. Film capacitors have a layer of dielectric, typically made of plastic or metal-oxide, which is sandwiched between two metallic plates. The dielectric film substrate provides the necessary electrical insulation and it also supports the metallic plates that store the electrical charges.

The WMF05P33K is a series of film capacitors designed by WMF Electro. They are generally used in high-quality audio applications due to their low ESR, temperature stability, and long life. This series has a rated voltage range of 5V to 35V and a capacitance range of 22uF to 470uF. It also has a large temperature range, from -40°C to +105°C.

The working principle behind film capacitors is based on Faraday\'s Law of induction. This law states that when a current-carrying conductor is placed in a magnetic field, an electric field will be induced in the conductor. The induced field will cause the current to move in the direction of least resistance, which will cause a voltage across the conductor.

To operate a film capacitor, electrical energy is applied to the two metallic plates. The top plate is connected to the negative side of the source, while the bottom plate is connected to the positive side. When this energy is applied, it induces opposite charges within the film sandwich. Due to Faraday’s law, the opposing charges will attract each other, while the charges on the plates will repel each other, thus creating an electric field. As the electric field builds up, a voltage is created across the plates, which causes the current to flow through the plates and the dielectric film.

The WMF05P33K is a series of film capacitors designed for use with audio applications. These capacitors provide a reliable, low ESR, temperature-stable and long-life performance. They are rated for a voltage range of 5V to 35V, and have a capacitance range of 22uF to 470uF. This series also has a large temperature range, from -40°C to +105°C. Additionally, the WMF05P33K is a very cost-effective solution for audio applications.
