Definition
MTBF stands for Mean Time Between Failures, which is
calculated according to the probability of accidental device
failures, and indicates reliability of devices. Therefore, it does
not necessarily represent a life of the product.
The life expectancy indicates average operating hours under
the ambient temperature of 40 C and a load rate of 50%.
Normally this is determined by the life expectancy of the N ll thi i d t i d b th lif
built-in aluminum electrolytic capacitor.
