The Quick Answer

MTBF means "Mean Time Between Failures."

More Observations...

"Mean Time Between Failures" (MTBF) is a reliability metric used to estimate the average time between failures for a specific component, system, or piece of equipment. MTBF is typically expressed in hours and is calculated by dividing the total operating time by the number of failures observed during that time. In other words:
  • MTBF = Total operating time / Number of failures.
A higher MTBF value indicates that the component or system is more reliable and less likely to fail, while a lower MTBF value suggests that the component or system is less reliable and more prone to failures. The MTBF metric is widely used in various industries, including electronics, manufacturing, and engineering, to evaluate and compare the reliability of different components or systems and to make informed decisions about maintenance schedules, product design improvements, and overall system reliability.
