Dielectric Strength of Insulating Materials
The dielectric strength of a material is the ability of the material to act as an insulator. It represents the voltage that a material of a given thickness will resist. With higher voltage than the dielectric strength, a spark will pass through the material.
Dielectric Strength Reference
The dielectric strength is usually given in volts per mil where 1 mil equals 0.001 in, or volts per meter.
Conversion factors:
- 1 V/m = 2.54×10⁻⁵ V/mil
- 1 V/mil = 3.94×10⁴ V/m
