Film Capacitors

Capacitor technology has been widely used in the fields of electronics, equipment and industrial applications since the mid-20th century. Film capacitors, especially the BFC2373EE104MD series, have been widely adopted in a broad range of industrial and commercial applications due to their reliable performance, high tolerance for environmental temperature ranges, and low impedance. This article will discuss the application field and working principle of the BFC2373EE104MD series film capacitors.

Application Field

The BFC2373EE104MD series capacitors are designed specifically for industrial and commercial applications. They have superior nonlinear capacitance properties which make them ideal for use in power supplies, inverters, lighting, studio equipment, power electronics, motor drives, current limiting, and many other similar applications. Due to their robust, stable, and rugged construction, they are also capable of providing reliable long-term operation in harsh environments and temperature extremes. The high temperature rating of the devices, up to 125°C, makes them perfect for high-power applications requiring reliable long-term power supply.

Working Principle

Film capacitors operate on the principle of dielectric polarization. Under an applied voltage, the resulting electric field causes the molecules of the dielectric material to rearrange themselves and form an electrical polarization, resulting in a molecular dipole. This dipole produces an electric field opposing the external electric field, and it is this opposition that causes a reduction in the output voltage amplitude. This phenomenon is known as dielectric absorption and is a common characteristic of all dielectric materials.

The BFC2373EE104MD series capacitors are constructed from dye-stabilized polypropylene dielectric material in a dry-film integrity design. This design provides superior nonlinear capacitance properties and improved storage characteristics. The mechanical and electrical characteristics of the dielectric material provide a dielectric strength and stability over a wide temperature range. The nonlinear properties of the dielectric material ensure that the capacitance remains effectively constant over a wide range of voltages and frequencies. The capacitor’s low ESR and current leakage abilities moreover aid in maintaining the device’s well-controlled power delivery to the connected circuit.

Conclusion

Overall, the BFC2373EE104MD series capacitors provide the ideal combination of low impedance, high stability, and reliable performance for a wide array of industrial, medical, and commercial applications. Their design also ensures a long life of reliable performance and superior nonlinear capacitance properties. With their robust construction and temperature capability, the BFC2373EE104MD series capacitors lend themselves to a broad range of medium- to high-powered applications where reliability and dependability are paramount.
