13. LIFETIME EXPECTANCY
The Lifetime expectancy 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 400h). Any number exceeding this value is a calculated
theoretical lifetime which can be used to compare devices.

14. MTBF
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 e.g. 1 000 000h
means that statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not
be determined if the failed unit has been running for 50 000h or only for 100h.
For these types of units the MTTF (Mean Time To Failure) value is the same value as the MTBF value.
