Which combination of relative permittivity and dielectric thickness produces the minimum capacitance?
Relative permittivity εr=3.2\varepsilon_r = 3.2εr=3.2, Thickness d=0.80 mmd = 0.80\text{ mm}d=0.80 mm
Relative permittivity εr=4.5\varepsilon_r = 4.5εr=4.5, Thickness d=1.50 mmd = 1.50\text{ mm}d=1.50 mm
Relative permittivity εr=6.4\varepsilon_r = 6.4εr=6.4, Thickness d=1.60 mmd = 1.60\text{ mm}d=1.60 mm
Relative permittivity εr=2.1\varepsilon_r = 2.1εr=2.1, Thickness d=1.40 mmd = 1.40\text{ mm}d=1.40 mm
