Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of capacitor used in a wide range of applications including energy storage, signal coupling, filtering, and many other uses. Film capacitors offer many advantages, such as high finesse, excellent ESD protection, low dielectric loss, small size, and robustness.

The BFC237673473 series is a range of film capacitors manufactured by DSP Control. These capacitors use a polyethylene-naphthalate (PEN) dielectric, and are designed for use in industrial applications where stability and long-term reliability are paramount.

Application Field

The BFC237673473 film capacitors can be used for a wide range of applications, such as filtering, buffering, decoupling, power factor correction, voltage regulation, and high-voltage filtering. Additionally, these capacitors are well-suited for providing energy storage for inductive loads such as relay coils and solenoids.

In particular, the BFC237673473 is a popular choice for energy storage in industrial control and automation systems, such as programmable logic controllers (PLCs) and robotic systems. These capacitors are also used in the power supplies of LED lighting systems and motors.

Working Principle

The working principle of the BFC237673473 film capacitors is based on the fact that when two electric fields are applied to a dielectric material, an electric dipole is created within the material. This electric dipole has a certain polarisation which is determined by the magnitude of the applied fields, and the direction of the electric dipole is determined by the relative orientation of the two fields. The electric dipole is then attracted towards one of the electrodes, causing charge to accumulate.

The dipole is formed when a voltage is applied across the film capacitors\' electrodes. This voltage induces an electric field which polarises the dielectric material. The electric dipole then accumulates at one of the electrodes, creating a separation of charge. The charge difference between the two electrodes creates a "capacitance" which is used to store energy.

The charge stored in the capacitor is then released when the applied voltage changes, producing a current. This current can be used to power various types of circuits, providing a stable and reliable source of energy.

The polyethylene-naphthalate used in the film capacitors of the BFC237673473 series is also highly non-linear, meaning that the capacitors are not limited by the conventional dielectric non-linearity of other capacitor types. This makes the capacitors suitable for a much wider range of applications, providing higher stability over temperature and voltage.

Conclusion

The BFC237673473 series of film capacitors is designed for use in industrial applications, providing stability and reliability over wide temperature and voltage ranges. The polyethylene-naphthalate dielectric used in the capacitors allows for high stability and a wide range of applications. These capacitors are suitable for use in energy storage, signal coupling, filtering, and voltage regulation in motors, LED lighting systems, relay coils, and robotic systems.
