Film Capacitors

Film capacitors are a type of capacitor consisting of a thin film of dielectric material placed between two electrodes. They are versatile components that can be applied in a variety of electronic circuits, thanks to their ability to withstand high voltage, low loss and wide range of capacitance values. The WMF6S1K-F is such a type of film capacitor, boasting many advantages and applications.

WMF6S1K-F Application Field

The WMF6S1K-F film capacitor is a radial leaded aluminum electrolytic capacitor, rated for 1600Vdc. This particular type of capacitor is used in various high power applications such as power supplies, DC-DC converters, inverters and DC motor drives. It is also suitable for other high voltage applications such as lighting ballasts and solar energy systems due to its long life (3000 hours) and high operation temperature (105°C).

WMF6S1K-F Working Principle

The principle of the WMF6S1K-F film capacitor starts with the dielectric material - which can be polyester, polypropylene, polyethylene, polycarbonate, polyimide, polyphenylene sulfide or Teflon. It is then sandwiched between two electrodes formed of aluminum foil with a thin film of electrolyte before being coiled around a base substrate. This substrate is then sealed in an epoxy housing with terminals attached. The dielectric is polarised by applying an electric field across it, creating an electric double layer at the surface which is for storing charge and giving the capacitor a specific capacitance value. This double layer is used to conduct the current and distribute the voltage across the entire surface of the capacitance instead of creating a short between the electrodes.

Benefits and Advantages

The benefits and advantages of the WMF6S1K-F film capacitor are wide reaching and make it a sound choice for a variety of electronics applications. It has a very long life of over 3000 hours, low ESR, low dielectric absorption, low self-inductance and a superb temperature stability with wide operation range.
