The purpose of this page is to give the viewer some idea of the relative resistive properties of a variety of materials that can be used in pulsed power, high voltage, and power conditioning applications. The data here has been taken from a number of sources including manufacturers data sheets, etc. Because actual conditions of measurement may vary, the reader is advised to contact the manufacturer for detailed information once a specific application has been defined. Ness Engineering is NOT a representative or dealer of any of these materials.
