Film Capacitors

Film capacitors, also known as plastic film capacitors, are a component that stores electrical energy as an electrostatic field. They are also used to stabilize power supplies, help reduce harmonic distortion and filter out high-frequency noise. In conventional capacitors, the dielectric medium between the capacitor\'s plates is a paper or oil-based material. Film capacitors use a dielectric medium in the form of a thin film, such as polycarbonate. This type of capacitor generally has superior characteristics and performance capabilities compared to paper, ceramic and electrolytic capacitors.

SFS28S55L375K-F application field and working principle

The SFS28S55L375K-F film capacitor is a polypropylene film dielectric, self-healing, Non-Inductive-type capacitor. The SFS28S55L365K-F has a wide variety of applications, but the most common applications are in the automotive and industrial industries. It can be used to filter and decouple signals, reduce high-frequency noise, and limit the inrush current. As for the working principle, when the capacitor is connected to a direct current, a voltage is applied to the dielectric which polarizes and generates an electrical field that creates an electrostatic attraction between the capacitor\'s plates. This electrostatic attraction gives the capacitor the ability to store electrical energy. As current flows through the capacitor, the electrical field charges it up, and when the current stops, the field remains and the capacitor slowly loses its charge.

The SFS28S55L375K-F has a low impedance value between its leads, with a typical capacitance of 18 uF and 25 VDC rating. This ensures the capacitor is well-suited for DC and pulses applications across a wide frequency range. It also has a low dissipation factor and low electrical noise, both of which are important factors in determining the performance of the capacitor.

Furthermore, the SFS28S55L375K-F offers a variety of other benefits in its applications. It has a low thermal EMF coefficient, ensuring that it maintains its capacitance over a wide temperature range.
