FCA1206C684M

Film capacitors are components that store electrical energy. They are also called plastic film capacitors, because the dielectric layer uses plastic film, not paper as in paper capacitors. The FCA1206C684M is a 0.01 μF 18 Vdc film capacitor with a tolerance of ± 10%. It has an operating temperature range of -55°C to +125°C.

Application Field

FCA1206C684M can be used in many applications, especially in high frequency and high voltage ones. These capacitors can be used for noise suppression and snubber circuits, high voltage AC/DC converters, DC/DC converters, power supplies, DC/AC inverters, variable speed drives and other similar applications.

These capacitors are also suitable for applications in an intense industrial environment such as LED devices as they have excellent insulation and offer high temperature stability even in extreme conditions. Due to its low capacitance and high voltage ratings, FCA1206C684M is also ideal for entertainment applications such as sound systems, portable equipment, and others.

Working Principle

Film capacitors are constructed by stacking one or more dielectric layers between two metallic electrodes. The electrodes are made from aluminum or other high conductivity metal, and the dielectric layer is made from a thin plastic film. The electrical energy in the capacitor is stored between the electrodes and the dielectric layer.

The FCA1206C684M film capacitor has two metalized layers. The two layers are separated by an insulation layer, which acts as the dielectric material. The metal layers act as electrodes, and current flows through them. When a voltage is applied to the electrodes, a charge begins to build-up and stored energy is generated. The capacitance of the device is determined by the thickness of the dielectric layer, and the closer the two electrodes are, the higher the capacitance. When the voltage level is lowered, the capacitor will discharge, sending the stored energy back into the circuit.

FCA1206C684M capacitors are low-noise, high-voltage, and high-temperature stable. They offer excellent insulation, superior temperature stability, low self-inductance, and low ESR. The capacitors are robust and reliable, making them ideal for a wide range of applications.
