Review of Recent Activities on Dielectric Films for Capacitor ...
AbstractPolypropylene (PP) film has been used in capacitors since 1970s. The high breakdown strength, low dielectric losses, and high availability make PP well suitable for use as capacitor dielectric. At the moment, the typical energy density achieved with PP film at room temperature is about 1.2 J/cm3. Recent research on PP films focus …
B8: Capacitors, Dielectrics, and Energy in Capacitors
Each dielectric is characterized by a unitless dielectric constant specific to the material of which the dielectric is made. The capacitance of a parallel-plate capacitor which has a dielectric in between the plates, rather than vacuum, is just the dielectric constant (kappa) times the capacitance of the same capacitor with vacuum in between ...
