6.3 Working Temperature
It is recommended that you use SLM156 at -30℃~+75℃ and take temperature control measures when
applications are in the harsh environment conditions. At the same time, a limited operating temperature
range of the module should be provided. Under this temperature conditions, some of RF indicators may
exceed. It is suggested that you store the applications under certain temperature conditions. Modules
beyond this range may not work or are damaged.
