1)
The calculated lifetime expectancy shown in the table indicates the minimum number of operating hours
(service life) and is determined by the lifetime expectancy of the built-in electrolytic capacitors. The lifetime
expectancy is stated in operating hours and is calculated according to the specifications of the capacitor
manufacturer. The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to
15 years (131,400 h). Any number exceeding this value represents a calculated theoretical service life which
can be used to compare devices.

MTBF stands for M ean T ime B etween F ailure, which is calculated on the basis of statistical equipment
failures and indicates the reliability of a device. It is the statistical representation of the probability of failure of
a device and does not necessarily represent the service life of a product.
The MTBF number is a statistical representation of the failure probability of a device. For example, an MTBF
number of 1,000,000 h means that statistically, if 10,000 devices are installed in the field, one device will fail
every 100 hours. However, it is not possible to determine whether the failed device has run for 50,000 hours
or only 100 hours.
