WebRTI (Reference Temperature Index) of a maximum of 130°C. Because of higher temperature requirements on PCB application and its components (like GaN and SiC), a new class of FR Material has been introduced. The FR 15 class. Materials inside this class are showing a max. RTI of 150°C. WebCTI value: maximum value of the voltage that caused in five testing samples – each with 50 drops – no failure. PTI value: the amount of the applied voltage, which has resulted in …
CTI: glossary - Multi Circuit Boards
WebAug 9, 2001 · Comparative Tracking Index [CTI]. In printed circuit board fabrication, CTI is a measure of the ability of the laminate surface to withstand tracking [carbonneous tracks on the surface, under wet contaminated conditions] across two electrodes placed on the surface, when an electrolyte is dropped between them. It is a test of the bare laminate. WebComparative tracking index (IEC 60112) CTI ≥400 to 600: Rated insulation voltage (III/3) 160 V: Rated surge voltage (III/3) 2.5 kV: minimum clearance value - non-homogenous field (III/3) 1.5 mm: minimum creepage distance (III/3) 2.2 mm: Rated insulation voltage (III/2) 160 V: Rated surge voltage (III/2) 2.5 kV: minimum clearance value - non ... ph wert basalt

WebThe “comparative tracking index” or “tracking resistance” is an indication of how well an insulating material withstands certain loads on its surface. In even more general terms, tracking resistance is an indication of how resistant a material is to environmental influences. Other loads occur in practice alongside partial discharges ... how do you adjust screen resolution
