Film capacitors, also known as plastic film capacitors, provide high capacitance in a small form factor and are well suited for use at high frequencies in circuits dealing with high voltage. They are most popularly used as storage capacitors for ripple current suppression, voltage linearity correction, AC power factor correction, and filtering applications in various electronic device designs. The BFC237862224 is a film capacitor designed to satisfy these corrosive and high temperature applications.

The BFC237862224 uses a combination of performance characteristics to facilitate its wide range of applications:  

• Operating range: The BFC237862224 is rated to operate within a wide temperature range from -25°C to 85°C. 
• Voltage rating: The film capacitor is rated to withstand an maximum operating voltage of 500V and maximum operating power of 35W at 200Hz.
• High capacitance values: The BFC237862224 can provide capacitance values from 0.1pF to 33,000pF with very low ripple current (<500μA) and low self-inductance (<1mH).
• High accuracy and stability: The BFC237862224 is designed to achieve tight tolerances in capacitance with typical capacitance tolerances of ±20%. The self-resonance Frequency (SRF) of the BFC237862224 is also relatively high to assure stable performance under high temperatures.
• No electrodes: The BFC237862224 employes a combination of ceramic and plastic materials, thus eliminating the need for micrometal electrodes. This will reduce the self-inductance and improves the electrical performance in ripple current suppression and voltage linearity correction applications.

The working principle behind the BFC237862224 is relatively simple. Inside the capacitor there are two layers; an anode and a polyethylene-terephthalate (PET) film. These two layers are separated by an insulator and are connected with two or more conducting strips. When a voltage is applied across the capacitor, the PET film act as an insulator and electrons flow from the anode to the film. This creates a difference in electrical charge between the two layers and generates a capacitance. 

The high dielectric constant of the PET film (free of water molecules) is what makes it desirable for high temperature, high voltage applications. The dielectric constant of polyethylene terephthalate is much higher than most other plastic materials, which makes for a higher-capacity film capacitor. Furthermore, the temperature coefficient of the PET film is low compared to most other plastic materials, which makes for a stable capacitance value over a wide temperature range.
