Electrical, Reliability and Radio Characteristics
6.1
Absolute Maximum Ratings
The absolute maximum ratings stated in
Table 11
are stress ratings under any conditions. Stresses beyond any
of these limits will cause permanent damage to XT65/XT75.
The power supply connected to the XT65/XT75 module shall be compliant with the SELV requirements defined
in EN60950. Above all, the peak current of the power supply shall be limited according to
Table 11
.
