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.

11. 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.
