Dielectric films tend to exhibit greater dielectric strength than thicker samples of the same material. For instance, the dielectric strength of silicon dioxide films of thickness around 1 μm is about 0.5 GV/m. However very thin layers (below, say, 100 nm) become partially conductive because of electron tunneling.
The dielectric constant K (kappa really) says how much a material responds to an electric field, by polarizing, partially canceling the field within itself. E(inside) = E(outside)/K. The dielectric strength says how strong an electric field you ne...

123 Dielectric Strength. Dielectric Strength reflects the electric strength of insulating materials at various power frequencies. Or it can be defined as the measure of dielectric breakdown resistance of a material under an applied voltage and is expressed as Volts per unit thickness. It is an indicator of how good an insulator a material is.
Dielectric strength is a measurement of a conformal coating's insulation effectiveness. The higher the numerical designation of strength, the more likely a coating is to resist dielectric breakdown — a level of 7,000 is dielectrically stronger than 2,200.
