Film capacitors, also known as polymer film capacitors or plastic film capacitors, make use of thin plastic film materials, such as polyester, polypropylene (PP) and polycarbonate, as their dielectric layers and forming the capacitor element. The dielectric materials provide excellent insulation characteristics such as high insulation resistance, low losses and thermal stability. These properties make film capacitors a very versatile component for a wide range of applications. The BFC237354334 film capacitor is a general purpose, non-polarized capacitor.

They are also used in audio transducers and speakers, and are becoming more common in mobile and laptop computers.

BFC237354334 Working Principle

BFC237354334 film capacitors are constructed with two electrodes, oneTerminal and one Case, which are separated by a thin dielectric layer. A film capacitor works by storing electrostatic energy in an electrical field generated between the two electrodes. The dielectric material, also known as the insulating material, isolates the two electrodes and prevents current from flowing through them.

When a voltage is applied to the electrodes, the electrical field established between them causes electrons to be drawn into one electrode and pushed away from the other. This creates a pool of stored electrons at one electrode and an equivalent number of vacant electron spots, or “holes,” at the other electrode, divided by a thin insulating layer. This electric charge continues to exist until the applied voltage is removed.

When the voltage is removed, the electrons will spontaneously return to their respective electrode. In doing so they release the stored energy, allowing for the capacitor to act as a filter to smooth or condition power. This is why film capacitors are one of the most commonly used components in power filtering and conditioning applications.

Conclusion

BFC237354334 film capacitors are a reliable, versatile, and cost-effective option for a variety of applications including power supply units, voltage regulation, audio transducers, and surge arresters. The dielectric materials used in these capacitors provide excellent insulation characteristics and have low losses.
