Film capacitors, sometimes referred to as plastic film capacitors, use thin film dielectric materials as their medium. This makes them especially suitable for use in high-voltage applications. Among these, F861BZ105M310A is a typical example. It is designed for use in high- frequency, low-impedance, high-voltage applications.

Application Field of F861BZ105M310A

F861BZ105M310A is a standard capacitors with a nominal capacitance of 105µF and a rated voltage of 310V. It can be used for high-frequency coupling cables, transmitting power lines, intermediate frequency amplifiers, and anti-interference fields of certain high-frequency applications. It offers excellent frequency characteristics and superior capacitance stability.

Working Principle of F861BZ105M310A

F861BZ105M310A is made from two layers of thin film: a ferroelectric polymer layer and an aluminum oxide layer. These layers are separated by a substrate of polypropylene. The ferroelectric polymer layer provides most of the capacitance and the aluminum oxide acts as a dielectric. The two layers are sandwiched between two aluminum-plated terminals, providing a high-dielectric field for the device.

When connected to a power source, an electric field is established between the two layers of thin film. The electric field causes the negative and positive charges to be separated and stored in the ferroelectric polymer, creating a capacitance. As the dielectric field increases, the capacitance also increases. The greater the field strength, the higher the capacitance of the capacitor. This allows F861BZ105M310A to provide superior frequency characteristics and greater capacitance stability.

In addition to providing high frequency characteristics, F861BZ105M310A also offers superior stability and low ESR. This makes it ideal for use in high-impedance circuits, such as intermediate frequency amplifiers. The low ESR also helps to reduce power loss due to power ripple.

Conclusion

In short, F861BZ105M310A is a reliable and robust film capacitor. Its excellent frequency characteristics and low ESR makes it ideal for use in high-frequency, low-impedance, and high-voltage applications. The high-dielectric field also provides superior capacitance stability, allowing it to handle larger capacitive loads than other capacitors.
