Film Capacitors, also known as polyester capacitors, polypropylene capacitors, and so on, are polarized capacitors with a foil element, normally aluminum, as the electrode and a film or an intumescent dielectric as the insulator. A typical film capacitor is marked with a code such as BFC237258393 which follows a specific pattern.This particular code indicates the type and size of the film capacitor; specifically, a bipolar film capacitor with a size of 3725. This particular designation is covered in IEC 60062 standard. Here, the first character “B” signifies bipolar capacitor, the second character “F” stands for film and the last 6 digit number “237258” indicates the case size of the capacitor. The last character “93” represents the tolerance in percentage of the capacitor’s capacitance.Film capacitors are mainly used in two general applications, filtering and energy storage. They are especially suited for use in high voltage, low frequency, high frequency and high stability applications. As film capacitors can be very easily integrated into a circuit with other components and as they have very low losses, they are ideal for any sort of circuit requiring these characteristics. As far as film capacitors are concerned, a larger capacitance usually indicates better performance.When film capacitors are used in filtering applications, they block and prevent the passage of high frequency noise while allowing low frequency signals to remain intact. They block any high frequency noise before it has a chance to interfere with the system. Film capacitors are also used in energy-storage applications to store electrical energy, which can then be discharged later.In addition, film capacitors are often used as timing devices to control the charging and discharging of other electronic components. The charge and discharge time of a film capacitor can be accurately controlled by selecting the right capacitor type and size.When used in a circuit, the BFC237258393 film capacitor is connected in a series with other components and then energized. This energizes the tantalum metal capacitive layers located between the electrodes, creating a capacitor with the desired capacitance. Once these layers are energized, the charge or energy stored in them remains intact until it is “bled off” through the circuitry.In conclusion, the BFC237258393 film capacitor is primarily used in the fields of filtering, energy storage, and as a timing device, and is connected in a series with other components once energized. Its low loss characteristics make it ideal for any circuit requiring these characteristics, and the size of the part is directly proportional to its capacitance value. Depending on its application, film capacitors can be selected to have precise capacitance values and discharge times.
