Dielectric Strength Disclaimer

Listed dielectric strength is based on laboratory testing a typical application with a 2X safety factor. Variations in desired safety factor, final product construction and geometry will impact these properties. Figures are provided as-is for initial consultation purposes. Machining and device components may alter these properties. Testing of final assemblies is the customer's responsibility for their application. Polygon especially recommends testing for all electrosugical devices.


Any ratings are typical for design purposes. Your design parameters may affect final ratings. Consult with a Polygon sales engineer for guidance. Final testing and approval is the customer's responsibility for their application. This information is derived from our testing and published data. There is no assurance of these properties, or warranty provided that these products are suitable for any particular purpose or operational situation.

Polygon certifies that their product will be free from material defect. Polygon will not accept any liability for loss, damages, or costs from use or misuse of our products.
