MTBF

Indicates the average time that repairable electrical and electronic equipment and components can operate continuously without failure. For a single piece of equipment or component, it is the average time from when a failure is repaired until the next failure occurs, and serves as an indicator of the reliability of the equipment or component. The longer this time, the lower the failure rate and the higher the reliability. The failure rate is the reciprocal of MTBF. For equipment or components that cannot be repaired, MTTF is used, which in this case represents the average lifespan.
