DC-DC Converters PCB Mount Type MG1R5, MG3, MG6, MG10 Instruction Manual8.2 MG6/MG10 Lifetime expectancy dependson stress by temperature difference!Product lifetime expectancy depends on case temperature difference(Tc) and number of cycling in a day is shown in Fig.8.4,Fig.8.5 (It is calculated based on our accelerated process test result.)If case temperature changes frequently by changing outputload factor etc., the above the lifetime expectancy design shouldbe applied as well. And point A which is shown in Fig.8.6 mustkeep below 105C.Lifetime expectancy [years]151051time ON/OFF/1day2times ON/OFF/1day3times ON/OFF/1day4times ON/OFF/1day5times ON/OFF/1day025 30 35 40 45 50 55 60 65 70 75 80Rise/fall temperature difference at point ATc [C]Fig.8.4 Lifetime expectancy against rise/fall temperature difference (MG6)Lifetime expectancy [years]151051time ON/OFF/1day2times ON/OFF/1day3times ON/OFF/1day4times ON/OFF/1day5times ON/OFF/1day025 30 35 40 45 50 55 60 65 70 75 80Rise/fall temperature difference at point ATc [C]Fig.8.5 Lifetime expectancy against rise/fall temperature difference (MG10)Point A (Center of the Case)Fig.8.6 Temperature Measuring Point on the case (Top View)!The warranty period is basically 10 years, however it depends onthe lifetime expectancy which is shown in Fig.8.4, Fig.8.5 if it isless than 10 years.MG-52
