Film Capacitors

Film capacitors are made from thin film plastic material and typically have relatively small capacitance values and low voltages ratings. The BF054D0155JDA series comes in a through hole axial-leaded package, making it easy to integrate with new or existing applications.

The BF054D0155JDA film capacitor is a polypropylene core device with a operating temperature range from -55°C to 125°C. Due to the low ESL, they are very popular in high frequency electronic devices, as well as providing stable frequency response characteristics.

BF054D0155JDA Application Fields

The BF054D0155JDA series finds use in many different application fields including high-performance audio, broadcast, aerospace systems, military electronics, and industrial electronics. It is especially suited for commercial and industrial power circuitry where capacitors with high ripple current capabilities and high power dissipation factors are necessary.

In addition, the BF054D0155JDA series film capacitors are also used in AC filtering applications, such as the attenuation of EM interference, the suppression of lingering afterglow from LCD screens, and the filtering of power lines requiring high instant high currents.

BF054D0155JDA Working Principle

The structure of a BF054D0155JDA capacitor consists of a conductive dielectric layer, such as a thin film plastic material, which is sandwiched between two metal electrodes. This creates a non-polarized capacitor whose capacitance value is determined by the area of overlap between the two electrodes, the dielectric material used, and the thickness of the dielectric film.

When an alternating current flows through the capacitor, the current causes an alternating voltage across the capacitor, which causes the capacitor’s capacitance to repeatedly expand and reduce in size. This phenomenon is known as capacitive reactance.

The capacitance of the BF054D0155JDA series is typically very low, ranging from1pF to 1uF. Therefore, it is best suited for low-power applications. However, due to its high working voltage and withstand voltage ratings – typically 1kV to 10kV – it is also used in high-voltage applications.

Conclusion

The BF054D0155JDA series film capacitor is suitable for use in a wide variety of applications, from low-energy applications to high-voltage applications. Due to its low ESL, it is especially suited for high-frequency electronic devices and provides stable frequency response characteristics.
