General Information

Reliability

The failure rate (λ) and mean time between failures

(MTBF= 1/λ) is calculated at max output power and an

operating ambient temperature (TA) of +40°C. Ericsson

Power Modules uses Telcordia SR-332 Issue 2 Method 1 to

calculate the mean steady-state failure rate and standard

deviation (σ).

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, λ

Std. deviation, σ

421 n Failures/h

60.9 nFailures/h

MTBF (mean value) for the BMR457 series = 2.91 Mh.

MTBF at 90% confidence level = 2.37 Mh

Compatibility with RoHS requirements

The products are compatible with the relevant clauses and

requirements of the RoHS directive 2011/65/EU and have a

maximum concentration value of 0.1% by weight in

homogeneous materials for lead, mercury, hexavalent

chromium, PBB and PBDE and of 0.01% by weight in

BMR457 series Fully regulated Advanced Bus Converters

Input 36-75 V, Output up to 25 A / 300 W
