Film capacitors, sometimes called plastic film caps or dielectric film caps, are electrical storage devices made up of an insulating film and two metal electrodes. The BFC247990242 model of film capacitor is used for high-frequency applications due to its low ESL and low ESR, making it an ideal choice for RF and audio circuits. It also features high peak current capability and low losses at high frequencies.

The construction of the BFC247990242 consists of two metallized layers of polypropylene film which are separated by a dielectric material. The film layers create two parallel plates which act as charge carriers, and the dielectric material between the plates acts as an insulator. The low ESR and ESL of the BFC247990242 are due to the high resistivity of the dielectric material, which reduces the amount of voltage across the plates. The total capacitance of the unit depends on the dielectric material, the thickness of the dielectric film, and the area of the plate.

The BFC247990242 is designed for use in high-frequency applications due to its low losses at higher frequencies. As the frequency increases, the power dissipation of the device increases as well. This is because the self-inductance of the device causes power to be dissipated across the device. At higher frequencies, this inductance can become significant and cause power loss due to the inductive effects. The low ESL and ESR of the BFC247990242 minimize these losses and thus, enable the device to achieve high frequencies.

In addition to its low losses at high frequencies, the BFC247990242 also features high peak currents. This is because the two plates, when charged, produce an electric field between them. This electric field increases as the voltage across the plates increases. At higher voltages, this electric field causes an increase in the current through the device. The high peak current capability of the BFC247990242 allows it to deliver high power for a brief period of time, making it well suited for power supply and filtering applications.

The BFC247990242 is an ideal device for high-frequency applications such as RF and audio circuits due to its low ESL and ESR, and high peak current capability. Its low inductance also makes it effective at higher frequencies and its high power handling capability enables it to be used in power supply and filtering applications. The BFC247990242 is made of two metallized polypropylene films, with a dielectric layer between. The total capacitance of the device depends on the dielectric material, the thickness of the dielectric, and the area of the plate.
