The answer is NO. The calculation of MTBF contain many variations, the version of MTBF, stress of component and the number of components can make difference. Not like other OEM/ODM companies, MEAN WELL sells standard power supply with our own brand, so the MTBF parameter is not able to customized one by one according to the application. Therefore, MEAN WELL still seek for improvement and MEAN WELL re-examined the MTBF parameters of TELCORDIA SR/TR-332(Bellcore) and implemented an optimization. MEAN WELL reviewing the supplier quality policy and accompanying with IQC/OQC/FQC…etc., all the ways to after-sales service, ensure preventing recurrence, which not only brings the quality of MEAN WELL products to another level, but it also changes the status of the quality factor πQ of the MTBF equation as shown in Table 1 according to TELCORDIA SR/TR-332(Bellcore) regulation. Leading the MTBF reading can be optimized from Level 0~I to Level I~II. For more detail, Although MTBF can be one of the parameter that represent quality, but it’s not the only parameter what we should consider when choosing a power supply. From Brand, price, lead time, service to warranty, all of them shall be well considered together.
