The Lifetime expectancy shown in the table indicates the operating hours (service life) and is determined by the

lifetime expectancy of the built-in electrolytic capacitors.

Lifetime expectancy is specified in operational hours. Lifetime expectancy is calculated according to the capacitor’s

manufacturer specification. The prediction model allows a calculation of up to 15 years from date of shipment.

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.
