MTBF
(1) The Lifetime expectancy that is shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime expectancy of the
built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the capacitors manufacturer specification. The
prediction model allows a calculation of up to 15 years (131,400 h) from date of shipment.
(2) MTBF represents Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a device. It is the statistical
representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.
All values except a battery.
