Film Capacitors: BFC247946304

Film capacitors, also known as plastic or polymer film capacitors, have emerged in the last two decades as an important alternative to traditional electrolytic capacitors. They are widely used in electronics components, especially in high-frequency and high-voltage applications. The BFC247946304 is one of the smallest and most versatile film capacitors available.

Construction

The BFC247946304 is constructed of a polypropylene film with 0.087-µm thick electrodes. The electrodes are made up of aluminum foil coated with a semiconducting material and then laminated onto the film. The capacitance range of the BFC247946304 series is 1-7 pF. The capacitance value is determined by the surface area of the electrodes. The high purity of the constructed BFC247946304 film capacitor ensures excellent reliability and stability of performances.

Applications

The BFC247946304 is used in various applications, such as telecommunications, digital systems, medical devices, and computer components. The polypropylene film of the BFC247946304 is suitable for applications requiring high frequency or high current. It is also well-suited for pulse applications due to its excellent pulse capability and low inductive characteristics. The small size and low profile of the BFC247946304 makes it ideal for use in space-constrained products. Its small size makes it suitable for applications where traditional capacitors would not fit.

Working Principle

The basic working principle of a film capacitor is simple. When the two electrodes of the capacitor are connected to a power source, an electric field is created across the dielectric material. This electric field stores energy in the form of an electric charge on each capacitor plate. If this electric field is strong enough, it will create a capacitance, which can store electrical energy. The amount of energy stored depends upon the capacitance of the capacitor which is determined by the dielectric material, its thickness, and the surface area of the capacitor plates.

Advantages

Compared to other capacitor types, film capacitors offer a number of advantages such as the following:

• High stability: The dielectric material used in film capacitors is highly stable even at high temperatures or when exposed to environmental conditions such as humidity.
• Low Equivalent Series Resistance (ESR): The ESR of most film capacitors is much lower than that of other types of capacitors, making them better suited for applications that require low impedance.
• Low Inductance: Film capacitors are also known for their low inductance which makes them better suited for high-frequency applications.
• High Surge Voltage: The high voltage rating of film capacitors makes them suitable for applications such as motor drives or UPS systems.
• Low Leakage Current: By using a dielectric with high leakage resistance, film capacitors have very low leakage current losses compared to other types of capacitors.
• Low Cost: Film capacitors are usually less expensive than other types of capacitors. This makes them the most cost-effective option in many applications.

Disadvantages

Despite their advantages, film capacitors also have some drawbacks. The main downside is the limited capacitance range. The range is limited by the size of the capacitance since increasing the capacitance will reduce the voltage rating. In addition, film capacitors are not suitable for applications that require high capacitance values or those that require a large number of capacitors.

Conclusion

The BFC247946304 is one of the most versatile and smallest film capacitors available. It is suitable for a wide range of applications due to its excellent stability, low inductance, high surge voltage, and low leakage current. The versatility of the BFC247946304 makes it an ideal choice for high-frequency and high-voltage applications as well as for space-constrained products. Its low cost also makes it a cost-effective option in many applications.
