Introduction to Film Capacitors

A film capacitor is an electrical component that relies on a thin polymer film, usually in the form of plastic, to store energy and demonstrate dielectric properties. Film capacitors are among the highest performance capacitor technologies available and are widely used in power electronics, RF applications, and pulse power applications. For instance, they are popular in applications that require high capacitance, low losses, and a long service life.The BFC246805155 is a polypropylene film capacitor manufacturer by ReStart Components. It has a capacitance of 0.047 μF (47nF) and a tolerance of 10%. This capacitor is suitable for applications such as FR-4 (print-circuit board material) and lead free soldering, as it can withstand soldering temperatures up to 260°C. The rated voltage of this capacitor is 100V DC with a peak test voltage of 143V DC, and a capacitance stability of 0.1%. This capacitor is RoHS (Restriction of Hazardous Substances) compliant and UL Component Recognized.

Uses of Film Capacitors

Film capacitors are highly scratch and vibration resistant, and have been proven to have superior technical characteristics compared to other capacitor technologies such as ceramic. They also offer significant advantages over other technologies in terms of their physical size and electron tunnel, making them perfect for high-density, compact designs. Film capacitors have an exceptionally broad range of applications, such as radio frequency (RF) circuits, medical equipment, mobile communications, computer networks, green energy applications, wireless base station powersupplies, renewable energy and many others. In some specialized applications, such as radio frequency (RF) switching, high-voltage switching, measurement, and high-voltage power supplies, the use of film capacitors can help reduce total size and weight for the equipment being utilized. As such, the use of film capacitors is becoming increasingly prevalent.In addition to their use in a wide range of applications, the use of film capacitors has become commonplace in the automotive industry. Film capacitors are used in vehicles to provide basic functions such as starting, powering lights, and playing the radio. The use of film capacitors helps reduce unnecessary wire clutter and helps improve the overall efficiency of vehicles.

Working Principle of Film Capacitors

The working principle of a film capacitor is quite simple. Inside the capacitor, two layers of thin plastic film serve as electrodes. An insulating material, usually air, separates the two layers. When a voltage is applied between the two electrodes, electrons are attracted or repelled from one layer to the other. The net result is a separation of charge between the two plates. This separation of charge is the basis of the capacitor’s ability to store energy. The key performance characteristics of a film capacitor are its dielectric loss and leakage current ratings. The dielectric loss measures the amount of energy that is lost in the capacitor due to the resistivity of the dielectric material. In general, the lower the dielectric loss, the better the performance of the capacitor. The leakage current is a measure of the current that is flowing through the capacitor in the absence of a voltage applied across the terminals. A good quality film capacitor should have a low leakage current.
