Figure 3.4 Fixing tabs and groove position
shows the recommended spacing to assure proper airflow by natural convection,
in
the worst case
– closed box done from a plastic (non-metallic) material with no ventilation
openings.
Whenever possible, ventilation openings shall be foreseen. Recommendations for their size and
position are presented in par.3.1.2.
Remark: In case of using a metallic box, with ventilation openings, all spacing values may be
reduced substantially. With proper ventilation, keep the air surrounding the iPOS4808 inside the
limits indicated. The spacing values may be reduced down to the mechanical tolerance limits of
Figure 3.1.
