Note
: Even if one of the parameters exceeds its absolute maximum rating even momentarily, the
quality of the product may be degraded. The absolute maximum rating therefore specifies the
upper or lower limit of the value at which the product can be used without physical damages.
Be sure not to exceed or fall below this value when using the product.
