 MTBF 
                            
                              | MTBF is Mean Time Between Failure, and is the predicted elapsed time between inherent failures of a system during operation. As same word, AFR (annual failure ratio) is 0.4%. MTBF can be calculated as the arithmetic average time between failures of a system.
