(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 capacitor’s manufacturer specification. The manufacturer of
the electrolytic capacitors only guarantees a maximum life of up to 15 years (131,400 h). Any number exceeding this value is a calculated theoretical lifetime, which can
be used to compare devices.
(2) MTBF stands for 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.
The MTBF figure is a statistical representation of the likelihood of a device to fail.
A MTBF
figure of for example, 1,000,000 h means that statistically one unit fails every
100 hours if 10,000 units are installed in the field. However, it cannot be determined if the failed unit has been running for 50,000 h or only for 100 h.
For these types of units the MTTF (Mean Time To Failure) value is the same value as the MTBF value.
