Failure rates are identified by means of life testing experiments and experience from the field. Typical values lie between 300‘000 and 1‘200‘000 hours. The MTBF value (= Mean Time Between Failure) is defined as the time between two errors of an assembly or device. Phase 3, the deterioration phase, is hardly relevant for electronic components.Īssuming that the failure rate λ is approximately constant, the equation can be simplified as follows: In this second phase, the standard failure rates for electronics components are defined and calculated. In the second phase, the admissible failures are defined, usually with a constant rate over time. In the first phase, one finds the early failure due to weakness in the materials, quality variations in production, handling mistakes and spurious, unconfirmed failures. Where to find the MTBF value of maxon controllers?Įach component has a failure rate curve in the shape of a bath tube, called Weibull distribution.How is reliability calculated for maxon controllers?.
