  • MTBF: Misquoted and Misunderstood
    datasheet - including those for power products. Mean operating time between failures (MTBF) is the most familiar way of specifying reliability. But even this simple measure can be misquoted and misunderstood. Datasheet producers use the term very loosely (sometimes deliberately, sometimes inadvertently
  • MTBF, MTTR, MTTF, FIT - Explanation of Terms
    The intent of this White Paper is to provide an understanding of MTBF and other product reliability methods. Understanding the methods for the lifecycle prediction for a product enables the customer to consider the tangible value of the product beyond set-features before purchasing it. MTBF, MTTR
  • MTBF of 700-Series Platform and Surface Mount Tiltmeters
    We reviewed our repair records for all 700-Series Platform and Surface Mount Tiltmeters sold during an 11-year period between February 9,1995 and February 8, 2006 to obtain an estimate of the mean time between failures (MTBF) for these instruments. These tiltmeters include all units with root model
  • Understanding Mean Time Between Failure (MTBF) for Process Instrumentation
    MTBF is largely based on assumptions and the definition of failure and attention to these details is important for proper interpretation.
    The concept of fatigue resistance in flexible shaft coupling design has been highly valued by R+W since its inception in 1990. For much of its first two decades in business the company focus was almost exclusively on couplings for high performance servo drive technology. When it comes to machinery
  • Product Power, Weight, MTBF, and Cooling Tables
  • Brushless motors with integral controls: The third wave of distributed motion aids reliability, MTBF
    Just as fractional horsepower gearmotors freed factories in the 1920s from their cumbersome, inefficient, and unreliable overhead "networks" of shafts and pulleys connected by leather belts, today's brushless servo motors with integral intelligent control allow machine builders to shorten product
  • Reliability of Capacitors
    MTBF (Mean time between failures) is the most commonly used reliability rating used today. Aluminum. electrolytic capacitors do not failure in a manner where MTBF can be used accurately. Instead of using. MTBF we use load life rating.
  • Reliability & Life Testing Handbook, Volume 2
    Reliability & Life Testing Handbook, Volume 2. Volume 2 covers the binomial tests of comparison (Accept-Reject Tests, the Sequential Probability Ratio Test, Bayesian MTBF and Reliability Demonstration Tests), as well as other important accelerated tests (Arrhenius, Eyriing, Bazovsky, and more).
  • Network Availability (.pdf)
    that every device will have a probability of failure. There are two main factors that are involved in the calculation of availability: Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR). MTBF is obtained from the data sheets of the equipment. MTTR is the average time to fix and restore
