BMR4540002/003 3.3 V / 40 A, 132 W For application specific configurations contact your local Flex sales BMR4540002/004 5 V / 38 A, 190 W representative. BMR4540000/002 9 V / 20 A, 180 W BMR4540000/001 12 V / 20 A, 240 W (Vin 40-75V) General Information Reliability BMR4540004/005 12 V / 20 A, 240 W (Vin 36-75V) The failure rate ( ) and mean time between failures Product Number and Packaging (MTBF= 1/ ) is calculated at max output power and an operating ambient temperature (T ) of +40C. Flex uses A BMR454 n1n2n3n4 /n5n6n7 Telcordia SR-332 Issue 2 Method 1 to calculate the mean Options n1 n2 n3 n4 / n5 n6 n7 steady-state failure rate and standard deviation ( ). Mechanical pin option x / Telcordia SR-332 Issue 2 also provides techniques to Mechanical estimate the upper confidence levels of failure rates based option x / on the mean and standard deviation.
