Film capacitors, also called plastic film capacitors or film dielectric capacitors, are a type of capacitor that uses a thin plastic film as the dielectric, sometimes combined with paper as the electrode (e.g. metallized paper capacitors). They are often used in audio-frequency and radio-frequency applications, and for power-supply decoupling applications. OTBJ504KNPIR-F is a film capacitor and it has an extensive application field and a working principle of its own.

Application Field of OTBJ504KNPIR-F

OTBJ504KNPIR-F is a Polyethylene Naphthalate (PEN) film capacitor. PEN capacitors are widely used in high-voltage DC, high frequency AC, high reliability AC/DC applications. OTBJ504KNPIR-F has a temperature coefficient of 0.1%, it is RoHS compliant, and it has a high ripple current capability, making it well suited for high-end applications. It is most commonly used in power supplies and power converters, LEDs, high-voltage DC applications, AC-DC converters, switch mode power supplies, military and aerospace applications, and telecommunications.

Working Principle of OTBJ504KNPIR-F

In a film capacitor, two metal plates (the electrodes) are separated by a thin layer of plastic film (the dielectric). The metal plates are typically connected to two metal leads and can be either wrapped around the plastic film or placed on either side of it. When a voltage is applied across the metal plates, an electric field is created across the plastic film. This electric field then causes a charge to accumulate on the plates, creating an electric potential energy between them. The higher the voltage applied, the more charge is stored, which increases the capacitance. The result is an electrical device that stores energy in the form of an electric field and can be used to filter or block high-frequency noise, reduce ripple in power supplies, and smooth the output of DC power.

OTBJ504KNPIR-F retains its capacitance and excellent electrical properties even at high temperatures, up to 105°C. Its superior dielectric properties make it ideal for use in high-speed switching circuits, high-frequency circuits, and high power applications. It also has a low dissipation factor across the frequency spectrum for superior signal integrity in DC, AC, and pulse applications.
