WebAug 30, 2024 · CVD diamond dielectric strengths are typically listed around 10,000 kV/cm, but some researchers and manufacturers report they have achieved dielectric strengths 30,000 kV/cm or more. The higher dielectric constant of diamond (5.6) compared to PC (3) or PFE (3.4) would translate to increased device capacitance for the same film thickness.
WebThe capacitance of electrolytic capacitors drifts from the nominal value as time passes, and they have large tolerances, typically 20%. This means that an aluminum electrolytic capacitor with a nominal capacitance of 47µF is expected to have a measured value of anywhere between 37.6µF and 56.4µF. thibaud duffeyWebElectrolytic aluminum capacitors can be manufactured with large capacitances.
