Application Field

The SFC24T35K291B-F is suitable for use in a range of applications such as DC/DC converters, automotive electronics, power supplies, and general electronic circuits. It is a cost-effective, high frequency capacitor which is designed to provide reliable operation and long service life in a variety of applications.

Working Principle

The SFC24T35K291B-F is a self-healing film capacitor which works by forming an electric field between two or more plates. When ac voltage is applied, the charge on each plate alternates between positive and negative. As the voltage increases, the electric field between the plates increases, causing a dielectric material which is between the plates to form a capacitor. The electric field also causes the dielectric material to become thinner, reducing the distance between the plates and thus increasing the capacitance.

The SFC24T35K291B-F is a reliable, long-lasting film capacitor which offers excellent frequency response and low ESR. As such, it is suitable for a wide range of applications in both consumer and industrial electronics.
