Film Capacitors

A film capacitor, often referred to as a capacitance film or dielectric film, is a type of non-polarized capacitor that is constructed using two electrodes and a film of dielectric material between them. The electrodes and the dielectric film create a barrier between the two electrodes, allowing only a limited amount of current to be passed through. The capacitor is then able to store a certain amount of electrical energy, making it suitable for a range of different applications.

One of the most popular models of film capacitor is the 170105K250NF. This model is designed to provide low ESR and high current handling capabilities, along with a long, expected operational life. The 170105K250NF utilizes PEN (polyethylene naphthalate) film for improved performance, reliability, and durability.

Application Field and Working Principle

Film capacitors are widely used in a variety of electronic equipment, including medical device, military hardware, automotive electronics, audio-visual systems, consumer electronics, and communications systems. They are ideal for DC/DC converters, EMC filters, AC line filters, snubber circuits, etc. The 170105K250NF model is typically used for small motor controls, or noise suppression for automotive and audio applications.

The working principle of the 170105K250NF is based on the same basic principle as other types of capacitors. It works by having two plates separated by a dielectric material, such as PEN (polyethylene naphthalate) film, which allows a certain amount of electrical charge to be held between the plates. When an electrical current is applied to the plates, it creates a potential difference between them, which causes the charge to be stored on the plates. When the current is removed, the stored charge is then released into the circuit.

Due to the qualities of the PEN (polyethylene naphthalate) film, the 170105K250NF film capacitor provides very reliable and accurate performance, as well as a long operational life. The model is available in a wide range of capacitance values, making it suitable for a variety of applications. It is also designed to resist moisture, corrosion, and vibration, which makes it an ideal choice for harsh industrial and automotive environments.
