MTBF Calculation and Component Derating Software
When designing a product, the Mean Time Between Failure (MTBF), Failure Rate, and Service Life are important parameters which are often required by end customers for compliance with standards and regulations. MTBF calculation is important for safety and reliability analyses of critical systems, but in recent years MTBF has also become a standard parameter for comparing the quality of consumer electronics.
Component Derating Analysis helps designers select the appropriate components Rating according to stress load and temperature. Optimal selection of components also improves the MTBF.
