Film Capacitors

Film capacitors are non-electrolytic capacitors made of different types of plastic film. They are known for being high-stability devices, and they are highly reliable in operations. Their construction allows them to operate at higher frequencies with very low distortion.

A BFC238312304 film capacitor is a polypropylene (PP) capacitor with a rated voltage of 400 volts AC and rated temperature of 70°C, 105°C, or 125°C. It has a capacitance range of 0.1μF to 2.2μF and dielectric constant of 250. Its operating range is from -55°C to +125°C.

Application Fields

BFC238312304 film capacitors are widely used in a variety of operations, such as found in AC frequency range of 50Hz to 10kHz. They are usually used in filtering applications, such as noise reduction, timbre adjustment, and waveform transformation. In addition, they also find application as snubbers, discharge capacitors, and in series-compensating applications.

This type of film capacitor is also suitable for use in telecommunications, automotive, and consumer electronic industries, where stability is of paramount importance. In these areas, special conditions impose rigorous requirements of working life, require operation in violent conditions, and need withstanding special processes. The BFC238312304 capacitor is able to satisfy the requirements of these applications.

Working Principle

The BFC238312304 film capacitor is composed of several layers of wound plastic film. The working principle of film capacitors is based on the fact that they accumulate charge when a voltage is applied or released when the applied voltage is removed. The capacitance of the device is determined by the relative dielectric constant of the plastic film and the distance between the individual layers, which is referred to as the “dielectric thickness”. The plastic film provides the dielectric field and the metal electrodes provide the conductive path.

Film capacitors have low ESL (equivalent series inductance, or residual inductance) and low ESR (equivalent series resistance, or residual resistance). The metal electrodes are connected to the plastic film by means of a conductive coating, which reduces the series inductance of the device, further increasing the efficiency of the capacitor. This allows the device to operate at higher frequencies with minimal distortion.

In addition to the various plastic films that can be used in a BFC238312304 film capacitor, it can also be constructed using a combination of different plastic films for higher ratings and temperatures. This is achieved by using several layers of plastic film insulation, in order to reduce the parasitic capacitance and increase the service life of the device.

Conclusion

The BFC238312304 film capacitor is a very reliable choice for a wide range of applications, including high-frequency operations, filtering, and telecommunications. Its high-stability and low ESR and ESL enable it to operate with minimal distortion in a variety of conditions. Furthermore, the BFC238312304 film capacitor is capable of withstanding special processes and working in violent conditions that impose rigorous requirements of working life.
