21FB4415A-F

Film Capacitors are widely used in electric circuits for a variety of applications. Examples include AC motors, digital data converters, electric actuators, power electronic components, and power supply units. The 21FB4415A-F is a type of film capacitor that is especially suited for high-voltage applications.

Construction and Features

The 21FB4415A-F is constructed with a polyimide film, wettable aluminum foil and a polyimide coating. This combination provides superior features such as high insulation resistance, excellent capacitance-to-voltage ratio, and excellent dry film performance. It also features good arc resistance and excellent dielectric strength. The 21FB4415A-F is also resistant to corrosion and mechanical shock and is suitable for use in extreme environments.

Applications

The 21FB4415A-F is an ideal capacitor for high voltage applications such as AC motors, power supplies, digital data converters, and electric actuators. It is highly suitable for stepper motor systems, brushless DC motor systems, DC/DC converters and voltage controllers. It is an effective capacitor for power electronics components and can be used in high-temperature, high frequency applications due to its superior arc and dielectric resistance.

Working Principle

The basic working principle of the 21FB4415A-F is to store electric energy within a medium such as a dielectric. When a voltage is applied, the electric field created by the voltage acts on the stored electric energy, charging up the capacitor. The capacitor then acts as an energy storage device, storing a certain amount of energy as a charge. The electric energy is released when the voltage is removed, allowing the energy to flow and be used in an electric circuit.

Advantages and Disadvantages

The 21FB4415A-F offers several advantages, including its low leakage current, its highly stable capacitance-to-voltage ratio, and excellent arc resistance. It is also resistant to corrosion and mechanical shock, making it suitable for use in extreme environments. In addition, it offers good dielectric strength and reliable performance over a wide temperature range. The primary disadvantage of the 21FB4415A-F is its limited energy storage capacity. The capacitance-to-voltage ratio also decreases as the capacitance increases, which can affect performance in some applications. Furthermore, its relatively high cost makes it more expensive than other types of film capacitors.

Conclusion

The 21FB4415A-F is a type of film capacitor that is widely used in high voltage applications, such as AC motors, digital data converters, and electric actuators. It offers a number of advantages, including its low leakage current, its highly stable capacitance-to-voltage ratio, and excellent arc resistance. Its primary disadvantage is its limited energy storage capacity. Although it is more expensive than other film capacitors, it provides reliable performance over a wide temperature range and in extreme environments.
