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.
The "Simulated Overall Failure Rate" means how many time the system will fail under 1 million hours, "Simulated Overall MTBF" means the average time between failure. The "Simulated Overall Life Time" means the life time of component having minimum life time. E-Cap and opto-coupler are considered to have life time issue.
Rather than showing overall failure rate, individual failure rate also been shown at the row of each component.
