The working principle of the SFP28S17.5L238K-F is based on the principle of capacitance. Whenever the terminals of an electric circuit have different potentials (voltage), a total electric field is set up, which in turn accumulates charges on the capacitor plates. The capacitance of the capacitor is determined by the charge accumulation on the plates, inversely proportional to the distance between the plates. The SFP28S17.5L238K-F consists of two metallic electrodes insulated from one another with an insulating film (dielectric), which ultimately determine its capacitance. Application of a voltage to the plates of the capacitor causes a change in the electric field between them, resulting in a process of charge accumulation on the plates.

The SFP28S17.5L238K-F is a reliable and resilient film capacitor and offers excellent performance in various power control, motor drive, temperature control, and power conversion systems. It’s resistance to extreme temperatures, humidity, and EMI make it a suitable solution for demanding environments. Additionally, its lead-free design ensures compliance with international environmental standards.
