General Information Reliability Ericsson AB 2010 The failure rate () and mean time between failures The information and specifications in this technical (MTBF= 1/ ) is calculated at max output power and an specification is believed to be correct at the time of operating ambient temperature (T ) of +40C. Ericsson A publication. However, no liability is accepted for Power Modules uses Telcordia SR-332 Issue 2 Method 1 to inaccuracies, printing errors or for any consequences calculate the mean steady-state failure rate and standard thereof. Ericsson AB reserves the right to change the deviation ( ). contents of this technical specification at any time without prior notice. Telcordia SR-332 Issue 2 also provides techniques to estimate the upper confidence levels of failure rates based on the mean and standard deviation. Mean steady-state failure rate, Std. deviation, 146 nFailures/h 38.3 nFailures/h MTBF (mean value) for the BMR451 series = 6.9 Mh. MTBF at 90% confidence level = 5.1 Mh
