SFT44S35-15K491E-F

Film capacitors are traditionally used to store and transfer electrical energy in high-frequency circuits. They are made of a plastic or metalized paper substrate with a dielectric layer coating that allows the dielectric material to hold an electric charge. The SFT44S35-15K491E-F film capacitor is one of the most popular models used for capacitive applications, mainly due to its high capacitance values, low ESR (dielectric dissipation factor), low inductance, and superior pulse loading characteristics.

The SFT44S35-15K491E-F film capacitors are designed for applications that require high capacitance, such as electronic filters and high-frequency signal bypassing. They can be used as DC power supply filters, as well as for RF and EMI filtering functions. Due to their high capacitance values, they can also be used to increase AC current or reduce harmonic components in circuits. The SFT44S35-15K491E-F film capacitors work well in audio crossover networks, where they are used to filter out any unwanted frequencies.

In addition, film capacitors such as SFT44S35-15K491E-F offer good dielectric stability for long-term operation. They are also known for their non-linearity characteristics, which help reduce RF interference and distortion. The self-healing feature of the dielectric layer enables it to block any short-term or intermittent electrical discharges. This will eventually prevent any permanent damage from occurring.

The SFT44S35-15K491E-F film capacitors come in a variety of sizes, ranging from 0.001 to 0.015 μF, and various voltage ratings for different applications. The working principle of the film capacitor is straightforward: when an electrical charge is applied to the capacitor, the dielectric material in the capacitor absorbs it and then releases it when the charge is removed. As such, the SFT44S35-15K491E-F film capacitor can be used for energy storage, buffering, and signal bypassing.

Overall, the SFT44S35-15K491E-F film capacitor is designed for applications such as DC power supply filters, RF/EMI filtering, and audio crossover networks. Its advantages include high capacitance values, low ESR, low inductance, and superior pulse loading characteristics. Its dielectric layer features non-linearity characteristics and self-healing capabilities for improved electrical performance.
