BFC2373FM225MI

Film capacitors have long been integral components of many electronic devices because they provide increased reliability and dependability in many applications. As one of the more popular types of capacitors, BFC2373FM225MI film capacitors demonstrate superb performance in many applications, both in consumer and industrial electronics. So, what are the application field of them and how do they work?

Application Field

There are a variety of high-performance and cost-effective uses for BFC2373FM225MI film capacitors. The main application field is the low-frequency area, such as various kinds of AC-DC power supplies, switched-mode power supplies, and electric motors. It can also be used for other applications, such as telecommunication equipment, home appliances like refrigerators and washing machines, electronic toys, camera, and computer equipment. Besides, BFC2373FM225MI film capacitors can also be found in many consumer electronic products as decoupling capacitors connection between two stages of amplifiers, and high-frequency AC sampling bridges.

Working Principle

The BFC2373FM225MI capacitors feature polyethylene-naphthalate (PEN) film as the dielectric material. This film is capable of minimizing losses at high frequencies and inhibiting charge leakage, making it an ideal choice for a wide range of power and high-frequency applications. To ensure capacitance stability over the rated temperature range, metallized construction is used with PEN film as the dielectric. The metallized film also promotes accelerated ageing process, removing the need to re-measure the ageing characteristic at specified time intervals.

The exact working principle of BFC2373FM225MI film capacitor is based upon the same concept as most other capacitors. A capacitor is essentially comprised of two conductors that are separated by an insulating medium, or dielectric. When a voltage is applied across the capacitor’s conductors, the positively charged ions in one will be attracted to the negative ions in the other conductor, and vice versa. This creates a static electric field that stores electrical energy. As the capacitance increases, so does the capacitors ability to store energy.

Conclusion

In conclusion, the BFC2373FM225MI film capacitors are widely used in a variety of low-frequency applications, such as AC-DC power supplies, switched-mode power supplies, electric motors, and telecommunication equipment. Thanks to the polyethylene-naphthalate (PEN) film, the capacitor offers superior performance in terms of preventing charge leakage. It also has a stable capacitance over a wide temperature range. The capacitor works on the principle of two metal plates being separated by a dielectric material, allowing the capacitor to store energy in form of an electric field.
