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

SpletDissipation factor is defined as the reciprocal of the ratio between the insulating materials capacitive reactance to its resistance at a specified frequency. It measures the inefficiency of an insulating material. If a material were to be used for strictly insulating purposes, it would be better to have a lower dielectric constant. Splet05. apr. 2024 · A fraction of the heat dissipated by electronic components is transferred to the PCB through the leads and cases, and the share increases with the rise in power densities.
