life of electronic components

[abhay kulkarni]

I want to know about the life of components used in SMPS
I know that input and out put capacitor's life varies to max. 5 years, but what is the life of other components such as FET, Transistors, output diodes, components in feed back ckt, pwm ic etc.
can any one explain?
and what about traditional power supply i.e. power supply with step down transformer, rectifier and capacitor
what is maximum life of both type of power supply with full load.

Look here.........

PowerEsim is a free web-based software providing power supply (SMPS) design, transformer design, magnetic design,
loss analysis, thermal analysis, waveform analysis, MTBF analysis, BOM building, DVT analysis and optimization of power supply (SMPS).

MTBF analysis is a tool to let user to add components and its corresponding stress one by one, then pressing a button,
the life time and MTBF of the system will be known immediately. User can treat it as a standalone tool to estimate the MTBF
and life time of any product. If a power supply has initialized, all the components and its corresponding stress in the power supply
will be seamlessly transfer to the tool for simulation.
