The values arise from their electronic polarization abilities, and materials with low values include perfect vacuum, gases such as helium, nitrogen, and dry air. The table below shows the dielectric constant of selected polymer conformal coatings. ...
Dielectric constant of common materials Dry air has a low dielectric constant. It can undergodielectric breakdown, a condition in which the dielectric suddenly begins to conduct electrical current. However, the breakdown is not permanent because when the excessive electric field is removed, air will ...

LiF is the most usually used in OLED among these materials for its performance in OLED. The dielectric constant of LiF, NaCl, NaF is 9.036, 5.895 and 5.072, respectively, at 300K [J. Fontanella, C. Andeen, D. Schuele, Phys. Rev. B 6 (1972) 582]. The thin film of these insulting...
Among all other printed circuit board laminate materials, they have the least thermal coefficient of dielectric constant. Moreover, the Rogers 4350 dielectric constant is steady with respect to a wide range of frequency. Insertion loss is greatly reduced due to the use of the LoPro copper foil ...
