BFC236821155

Film capacitors are a large category of capacitance components, and they are also widely used in switching power supplies, communication equipment and other fields. The BFC236821155 is a film capacitor that is often used in switching power supplies and electronic circuits. This article will explain the working principle of the BFC236821155 and what fields it should be used in.

The BFC236821155 is a film capacitor with a dielectric of polypropylene and self-healing technology. The outer one of the two electrodes is a metal-polymer foil with a fine etching structure. The combination of the polymer layer and the metal-layer provides better properties, the most notable being the prevention of expanding or cracking during an overload current surge. Due to the lower inherent losses, the BFC236821155 has a higher energy density than other capacitors, making it suitable for high frequency and high power circuits.

The BFC236821155 works by holding an electrical charge between the two electrodes. The dielectric of the polypropylene has a high dielectric constant, which allows the capacitance to retain a large charge. The capacitance of the BFC236821155 is relatively stable due to its self-healing designs. When the capacitance is overloaded the electrodes of the capacitor will break down and the metal-polymer foil will reform and re-establish the original capacitance.

The BFC236821155 is mainly used in high frequency and high power applications. As mentioned before, it can withstand high currents which makes it suitable for switching power supplies. Additionally, it is suitable for applications such as power filters, voltage stabilizers, communication equipment and AC motors. It is also suitable for high voltage DC circuits due to its low inherent losses and high energy density.

To sum up, the BFC236821155 is a film capacitor with very good properties. It has a high dielectric constant, meaning it can hold a higher charge than other capacitors. Additionally, it has a self-healing feature, which prevents cracking and expanding under overloads. Lastly, it is suitable for high frequency and high power applications, such as communication equipment, AC motors and voltage stabilizers.
