Table 6

USEFUL LIFE AND ENDURANCE

Table 7

Endurance can be calculated by formula below:

Lr: estimated lifetime (h)

L0: base lifetime specified at maximum operating temperature with applied the DC voltage (h)

T0: rated maximum operating temperature (°C)

Tr: actual ambient temperature (°C)

Table 8



Statements about product lifetime are based on calculations and internal testing. They should only be interpreted as estimations. Also due to external factors, the

lifetime in the field application may deviate from the calculated lifetime. In general, nothing stated herein shall be construed as a guarantee of durability.
