Introduction to Film Capacitors

A film capacitor, also known as an electrical film capacitor, plastic-film capacitor, polyester capacitor or just plain film cap, belongs to a family of capacitors in which one or more pairs of conductors are separated by an electrical insulator. Film capacitors are widely used in all kinds of electrical and electronic equipment, especially in signal and telecommunications. They come in a range of sizes, shapes, styles, and working principles.

BFC247012105 Application Field and Working Principle

The BFC247012105 film capacitor is manufactured by a company called ROHM Semiconductor. It is mostly used in the communication and networking, power and industrial, automotive and medical electronics industries. The capacitor is a self-healing, low-ripple, high capacitance film capacitor with a high dielectric strength. It has an operating temperature range from -40°C to 105°C and a rated voltage of 1,000 volts.

The BFC247012105 capacitor has a metalized film dielectric, which basically acts like a thin layer of aluminum insulation between two sheets of polyester dielectric material. This structure is designed to reduce heat buildup while maintaining a high dielectric strength. The capacitor\'s housing is made from non-flammable plastic. Its terminals are sealed off to prevent leakage and ensure long-term stability.

When the capacitor is connected to a power source, an electric field is created within the capacitor. This electric field creates an energy storage between the two electrodes, which is known as capacitance. The amount of energy that can be stored within the capacitor depends on the number of layers of dielectric material between the conductive electrodes. Generally, the more dielectric layers, the higher the capacitance of the capacitor.

The BFC247012105 film capacitor has a very low equivalent series resistance (ESR) so that it can respond quickly to changes in voltage or current. It has a high decoupling capability that can reduce electromagnetic interference and prolong the life of electronic devices. The high capacitance of the capacitor also enables it to reduce voltage spikes and prevent short circuits.

Advantages of BFC247012105

One of the main advantages of the BFC247012105 film capacitor is that it has a high electrical capacitance, which means it can store a large amount of energy in a small package. Its low ESR also means it can respond quickly to changes in voltage or current. Its high decoupling capability also reduces electromagnetic interference and prolongs the life of electronic devices.

The capacitor\'s housing is made of non-flammable plastic, adding to its durability and reliability. Its terminals are sealed off to prevent leakage and ensure long-term stability. Its wide operating temperature range also ensures reliable performance in extreme temperatures.

Conclusion

The BFC247012105 film capacitor is a high-performance capacitor that is suitable for a wide range of applications. It offers high electrical capacitance, low ESR, and high decoupling capabilities. Its nonflammable housing and sealed off terminals also make it highly reliable and durable. This makes the BFC247012105 an ideal choice for many applications in the communication and networking, power and industrial, automotive and medical electronics industries.
