Note: For applications with an expected voltage over 480 Volts AC, Bergquist recommends a dielectric thickness greater than 0.003" (76μm). Note: Maximum test voltage is a function of material and circuit design.Typical proof test does not represent the maximum. Note: Circuit design is the most important consideration for determining safety agency compliance.
