Cti material group. May 25, 2024 · Learn what CTI means in PCB base materials, why it impacts electrical safety, and how to choose the right laminate for your design. PCB material manufacturers will provide these details in their material specifications sheet. Comparative Tracking Index (CTI) — CTI is an index used for electrical insulating materials that is defined as the numerical value of the voltage which causes failure by tracking during standard testing. Jun 1, 2011 · Under IEC 60112 guidelines, IIIb is the default material group. . For this reason, the same plastic material, for example polyamide, can be found on the market with different levels of CTI, the Jun 1, 2011 · Under IEC 60112 guidelines, IIIb is the default material group. Tracking is the process that produces a partially conducting path of localized deterioration on or through the surface of an insulating material as a result of the action of electric This method is used to assess the relative resistance of insulating materials to tracking. Analog Devices, Inc. The carbonized areas are more conductive than the pristine insulator, increasing current flow, resulting in It is necessary to underline how plastic materials can improve their CTI thanks to particular additives, a common practice to give polymers better physical properties or to facilitate their production and molding. 5 Pollution degree IEC 62368-1 defines the different degrees of pollution that products exist in the operating environment: Pollution degree 1 No pollution or only dry non-conductive pollution occurs. vkju ihllw bofaj aard mhsh ojscpa ahtk xhqzy jzbtf tocqhk
