Film Capacitors

Film capacitors are widely used in various types of industrial applications due to their high reliability, small size and excellent electrical characteristics. The BFC237125223 series film capacitors, or polyester film capacitors, are a popular choice for applications requiring high dielectric strength and excellent insulation. This popular series of capacitors can be found in electronic and industrial equipment, such as medical systems, circuit boards, motors, power supplies, and more.

BFC237125223 Application Field

The BFC237125223 polyester capacitors are mostly used in DC-link, filter, and by-pass applications due to its high dielectric strength and low ESR. This type of capacitor is also suitable for use in power supplies, motors, interference filters, and harmonic suppression filters in industrial automation applications, such as industrial robots, machine tools, and process control systems.

BFC237125223 Working Principle

The BFC237125223 series capacitors are made using a polyester dielectric material and an aluminum foil. The dielectric material provides the necessary electrical insulation while the aluminum foil ensures lower ESR and provides high dielectric strength. The capacitance of this type of capacitor is a function of the air gap between the electrically separated aluminum foils of the capacitor, as well as the thickness of the dielectric layer between them. When a current flows through the capacitor, the aluminum foils and dielectric material generate a charge in the opposite direction, which creates a potential difference between the two terminals of the capacitor. This potential difference delivers the required voltage and power.

The BFC237125223 series of capacitors has a high capacitance, low impedance, and excellent temperature stability. The capacitance of this type of capacitor is usually between 0.1uF – 4.7uF, and its working temperature range is -55°C – +105°C. It has a high dielectric strength of 4kV/mm, high insulation resistance, excellent stability and low dissipation factor. It is also highly resistant to environmental influences and has a high ripple current of 6.4A/100kHz.

Conclusion

The series of BFC237125223 film capacitors is a popular choice for various types of industrial applications due to its high reliability, small size, excellent insulation, and high dielectric strength. This series of capacitors provides high capacitance, low impedance, excellent temperature stability, high insulation resistance, and high ripple current. It is also highly resistant to environmental influences, making it a great choice for many applications.
