Film capacitors, also known as film dielectric capacitors, are passive electrical components used widely in various low and medium power electronic applications. The BFC2370CB184 is a film capacitor with a high insulation resistance, self-healing properties, and excellent physical stability. It is typically used in power factor correction applications, for suppressing interference in power and audio circuits, and for general purpose decoupling in applications. It features an operating temperature range of -20 °C to +105 °C.

The BFC2370CB184 film capacitor has an electrolyte-free construction using polypropylene as a dielectric material. The superior insulation material used has excellent dielectric properties to ensure high insulation resistance and excellent stability from temperature and frequency, with little feedback. It is rated at 2.2 uF, with an rated voltage of 105 WV DC, making it an ideal choice for many industrial and power applications, as well as for audio circuits.

The construction of the film capacitor is designed to allow for a property known as ‘self-healing’ or ‘self-restoration’. In construction, a thin dielectric sheet of polypropylene is placed between two metal plates. This metal plate and the dielectric sheet are then connected to two electrodes connected to the capacitor terminals. When a voltage is applied to the capacitor, the dielectric sheet is ionised and an electric field is generated.The electric field causes the current to be forced to the outer surface of the dielectric. This creates a large number of charge carriers which would cause the voltage to drop to zero. However, the self-restoration property of the film capacitor ensures that the voltage does not drop to zero; instead, a low resistance path always occurs through the dielectric, allowing the capacitor to carry current without suffering major damage to the structure. This makes the BFC2370CB184 Film Capacitor an ideal choice for use in applications requiring a high level of stability, and protection against high voltage transients.

The BFC2370CB184 film capacitor is also a highly reliable capacitor, with an operating life of more than 100,000 hours. It is designed with internal temperature sensors which ensure that the capacitor does not become over-heated in high temperature or high voltage environments. It has low dissipation factor which ensures low power loss and excellent EMC (electromagnetic interference) performance, resulting in improved noise rejection in applications sensitive to radio frequency interference. The device meets the requirements of EN60384-1 and has excellent tolerance and low dielectric loss characteristics.

In conclusion, the BFC2370CB184 film capacitor is a high quality and reliable device designed for low and medium power applications. It has low dissipation factor, excellent stability, and excellent EMC performance. It also has self-healing properties which make it very suitable for use in power factor correction and audio circuits. With a long operating life and an operating temperature range of -20°C to +105°C, the BFC2370CB184 film capacitor is an ideal choice for many industrial and power applications.
