Splet16. jun. 2024 · Loss tangent (tanδ) or dissipation factor (Df): The loss tangent or dissipation factor is the tangent of the phase angle between the resistive and reactive currents in the dielectric. The dielectric loss increases with increasing values of Df. Low values of Df result in a “fast” substrate while large values result in a “slow” substrate. Splet> Dissipation Factor (Df) (also called loss factor or dielectric loss) is defined as the power dissipated by a dielec-tric, generally less than or equal to 0.03 at 1 kHz and less than or equal to 0.05 at 1 MHz, according to ASTM D150. > Dielectric Strength (sometimes referred to as breakdown voltage) is the maximum electric field a material
