Working Principle

The BFC238042303 film capacitor utilizes the dielectric capacitance between two metal plates to create a capacitive current. The dielectric material consists of two layers of polypropylene film separated by an aluminum oxide layer in between. The polypropylene film provides insulation between the metal plates. As the voltage across the metal plates is increased, the electrostatic fields generated between them cause the dielectric material to charge up and store the electric energy in the form of capacitance. 

The capacitance created by the BFC238042303 is temperature dependent, with variations of up to 10% over a wide range of temperatures from -40°C to 85°C. This temperature compensation means that the capacitance of the BFC238042303 will remain consistent regardless of temperature fluctuations. Additionally, it has a wide frequency range, ensuring that it can be used in complicated circuits that require a wide range of frequencies.
