Film Capacitors

Film capacitors are components based on thin polyester or polypropylene films. Film is thin, flexible, and tough. In comparison with other capacitor dielectrics, the film has higher permissible strain and higher maximum operating temperature, as well as good stability of capacitance and insulated resistance. They can be used in applications where long life is required.

BFC237265123 Application Field and Working Principle

BFC237265123 film capacitors are widely used in signal filter circuits, power circuits, and industrial equipment. They blend high capacitance, low loss, long life, low noise, and high reliability. The working principle of film capacitors is based on the principle of electric double layer formation, which states that when a non-conductive material is placed between two conductive electrodes and voltage is applied, the material acquires electric charge and forms an electric double layer. This creates a barrier to the flow of current.

When a direct current is applied to a film capacitor, the capacitor acts as an insulator, because electric charges accumulate on both sides of the electric double layer. The capacitance of the capacitor is determined by the width of the electric double layer and the distance between the two electrodes. When an alternating current is applied, the electric charges on the two surfaces of the electric double layer oscillate with the same frequency as the current, and this causes a rise in the capacitance of the capacitor.

BFC237265123 film capacitors offer a variety of benefits. Due to the excellent dielectric properties of the film, these capacitors are highly stable and have a high level of insulation resistance. They are also resistant to vibration, moisture, and heat. Moreover, these capacitors can operate at high temperatures (up to 125°C) and have a long service life. In addition, they are low-cost, low-noise, and highly reliable.

Due to their excellent performance and reliability, BFC237265123 film capacitors are widely used in various applications such as telecommunication, industrial automation, power supplies, lighting, automotive electronics, aerospace, and medical equipment.
