DC-DC Converters PCB Mount TypeMG15, MG30, MG40, MG80Instruction Manual11.3 MGF40 Lifetime expectancy depends on stress bytemperature difference!Product lifetime expectancy depends on case temperature difference(Tc) and number of cycling in a day is shown in Fig.11.5 (Itis calculated based on our accelerated process test result.)If case temperature changes frequently by changing output loadfactor etc., the above the lifetime expectancy design should beapplied as well. And point A which is shown in Fig.11.6 must keepbelow the values determined by the derating curve.11.4 MGF80 Lifetime expectancy depends on stress bytemperature difference!Product lifetime expectancy depends on case temperature difference( Tc) and number of cycling in a day is shown in Fig.11.7 (Itis calculated based on our accelerated process test result.)If case temperature changes frequently by changing output loadfactor etc., the above the lifetime expectancy design should beapplied as well. And point A which is shown in Fig.11.8 must keepbelow the values determined by the derating curve.Lifetime expectancy [years]151051time ON/OFF/1day2times ON/OFF/1day3times ON/OFF/1day4times ON/OFF/1day5times ON/OFF/1dayLifetime expectancy [years]151051time ON/OFF/1day2times ON/OFF/1day3times ON/OFF/1day4times ON/OFF/1day5times ON/OFF/1day030 35 40 45 50 55 60 65 70 75 80 85030 35 40 45 50 55 60 65 70 75 80 85Rise/fall temperature difference at point ATc [C]Rise/fall temperature difference at point ATc [C]Fig.11.5 Lifetime expectancy against rise/fall temperature differencePoint A (Center of the Case)Fig.11.7 Lifetime expectancy against rise/fall temperature differencePoint A (Center of the Case)Fig.11.6 Temperature measuring point (Top View)Fig.11.8 Temperature measuring point (Top View)!The warranty period is basically 10 years, however it depends onthe lifetime expectancy which is shown in Fig.11.5 if it is less than10 years.!The warranty period is basically 10 years, however it depends onthe lifetime expectancy which is shown in Fig.11.7 if it is less than10 years.MG-88
