Film capacitors are used in a variety of applications in the field of electronics. The SFT37S90K391B-F is a type of specialized film capacitor specifically designed to be used in audio applications. This capacitor is ideal for achieving high-frequency, ac coupling, high-resolution servo loop, and other audio applications that require high performance and precision.In terms of design and construction, the SFT37S90K391B-F is a metallized polypropylene film capacitor, also known as an "over-resonated" capacitor. This type of capacitor has a substrate layer made up of a special type of polyester film. This film is sandwiched between metal electrodes of two different materials. The metal that is used for the two electrodes usually consists of aluminum foil with an tin-plated copper coating with an additional epoxy coating to provide better electrical characteristics.The two metal electrodes on the SFT37S90K391B-F are joined together to act as one large metal plate, instead of two individual electrodes. The combined metal plate forms a complex dielectric field, which increases the capacitor\'s efficiency and decreases its losses. As a result, this capacitor has a high resonance frequency, meaning it can be used for very high-frequency applications.In addition, the SFT37S90K391B-F has an ultra-low ESR (equivalent series resistance) rating and a dielectric strength of > 5 kV, which makes it an ideal choice for providing reliable and high-performance coupling voltage. The SFT37S90K391B-F also features a high surge current rating of > 10A, providing an even greater margin of safety for other components that may be connected to the capacitor.In terms of working principle, the SFT37S90K391B-F functions like any other capacitor. When an electrical signal is applied to the capacitor, a dielectric field is created across the two electrodes. This dielectric field stores electrical energy until the signal is removed. After the signal is removed, the stored electrical energy is released and the capacitor gradually returns to its original state.The SFT37S90K391B-F is an excellent choice for audio applications due to its high performance, precision, and reliability. It is able to provide exceptional ac coupling, high-resolution servo loop, and high-frequency applications. In addition, it has a very low ESR rating and a high surge current rating. This makes the SFT37S90K391B-F an ideal choice for many audio applications.
