Film capacitors are a type of capacitor which uses a thin plastic film as a dielectric material, and its electrodes are usually metal coated with an oxide layer. The BFC2370GC103 is a film capacitor designed for high voltage and frequency applications, including power supplies, IGBT (Insulated Gate Bipolar Transistors) circuits and lighting ballasts.

The BFC2370GC103 is a non-polarized capacitor, meaning that the voltage can be polarity-independent, and can be DC or AC. It has low losses at higher frequencies, which makes it suitable to be used in high-frequency and pulse current circuits. This capacitor is also characterized by stable capacitance and low dissipation factor over a wide temperature range, meaning it will remain within the designed specs with temperature variations.

Since the dielectric material used in this capacitor is multi layer polypropylene film, it has very low leakage current and is resistant to moisture, as well as to vibration, making it an excellent choice for higher voltage and temperature applications. Apart from the low leakage phase and excellent electrical characteristics, the BFC2370GC103 has a high ripple current tolerance. This makes it suitable for applications with high ripple currents, and the capacitor can withstand such conditions very well.

The working principle of the BFC2370GC103 is easy to understand. When a voltage is applied to the film capacitor, an electric field is created between the capacitor’s plates. This electric field stores the energy stored in the capacitor and also creates an ESR (Equivalent Series Resistance) along the length of the capacitor’s plates. This ESR affects the current that the capacitor can provide. The higher the voltage, the higher the ESR and thus the lower the current the capacitor can provide.

In conclusion, the BFC2370GC103 film capacitor is designed for high voltage, frequency, and temperature applications. It has low losses, good electrical characteristics, a high ripple current tolerance, and a low ESR. It is perfect for use in power supplies, IGBT circuits and lighting ballasts.
