Film capacitors, also known as plastic film capacitors or film dielectric capacitors, are passive electronic components made up of a thin insulator known as a dielectric material and two metal plates. The dielectric material acts as the medium for storing charge, and the metal plates act as the two electrical contacts (or electrodes) that allow the capacitor to transfer electric charge in and out of the dielectric material. The dielectric material most commonly used in film capacitors is polyester, although many other types of films exist. The type of film used affects the overall performance, stability, and longevity of the capacitor.

The 168104K63A-F is a class X1 type film capacitor, designed to provide added safety for applications in line with IEC/EN60384-14 standards. It has a rated voltage of 250V and a tolerance of ±10%. It is a polarised capacitor with radial leads and insulation wrapping that covers the line of solder. It is generally used in mains-powered applications to reduce the surge current in situations with high voltage or high-frequency switching, to reduce the occurrence of electrical shocks caused by contact of the switch current with the device.

The operating principle of the film capacitor is based on electrostatics. When voltage is applied to the metal plates, the dielectric absorbs electrons, forming regions of negative and positive charge that create an electric field. This electric field stores energy, which can then be discharged when the voltage across the capacitors is rapidly reduced. The capacitance of a film capacitor is uniquely determined by its geometry, amount of material, and dielectric constant of the material used. This makes it particularly useful for applications in which the exact capacitance must be carefully calibrated, such as in filter and oscillator circuits.

In addition to its primary use in mains-powered applications, the 168104K63A-F is also suitable for applications such as welding machines, electronic ballasts, water heaters, automotive electronic devices, control circuits, HID lighting systems, medical equipment, and more. It is one of the most popular and widely used capacitors on the market due to its high reliability and consistent performance.
