Film capacitors, also called plastic film capacitors, are electrical components used for their ability to store energy in electrostatic fields and to take advantage of dielectric polarisation. They are constructed with a dielectric film deposited on an electrolytic or ceramic substrate to create effective capacitance. Film capacitors are highly reliable, with long lifetimes and low leakage and volumetric performance. The WMC08S56K-F is a film capacitor designed for use in a wide range of applications.

The WMC08S56K-F is essentially an isolated capacitor whose layers are constructed with conductive copper and dielectric plastic film. The two layers of conductive material form a capacitor with internal connections, which isolates the contacts from noise and other electrical interference. This is an advantage in applications such as spark-gaps, where the capacitor is exposed to extreme environmental conditions. The plastic film isolates the inner copper plates from corrosion, making the device highly reliable in a wide range of temperatures.

The WMC08S56K-F is a low power film-based capacitor designed for a range of applications, including in high-frequency and high-voltage circuit boards and power supplies. The capacitor is able to provide up to 1.2µF of capacitance at ≤ 500V, making it suitable for use in automotive, medical, and industrial applications, such as ballasts, electrical relays, motors, etc. The capacitor is highly resistant to high-frequency electrical, magnetic, and vibration stresses.

The WMC08S56K-F’s working principle is based on a principle of dielectric polarization. When a voltage is applied, the dielectric material in the capacitor form a barrier between the two conductive plates to prevent the flow of direct current (DC) but makes possible the alternating current (AC) surge to pass through. As the applied voltage increases, the electric charge stored in the capacitor increases as electrons are drawn to the negatively charged plate. This increases the surface energy of the capacitor and the capacitance.

The WMC08S56K-F capacitor, named for its 8 mm X 55 mm X 50 micron (µm) dimensions, is a high performance, high reliability device. The compact, lightweight design makes it easy to integrate into applications. Its low ESR, combined with its high energy density, makes it suitable for use in mission-critical applications. The high hold-up voltage capability makes it suitable for use in high-voltage applications such as electrical networks. The WMC08S56K-F film capacitor is RoHS-compliant, making it environmentally sound.

In summary, the WMC08S56K-F film capacitor is a highly reliable device designed for use in a wide range of applications. Its small size and low ESR, combined with its high energy density, make it suitable for mission-critical applications. It is RoHS-compliant and suitable for use in high-frequency and high-voltage circuit boards and power supplies. Its working principle is based on dielectric polarization, and its construction with a dielectric film deposited on an electrolytic or ceramic substrate creates effective capacitance.
