*1)
- 50mm above surface
- only main output is loaded (no load on fan out)
*2)
- Limited by fan specification to max 70°C .
*3)
- Tested with airflow direction G (see Application Note)
- Best airflow direction is from top or sides. Customer to ensure airflow rate and direction to keep
components temperature below the limits.
- If fan output is used PPTC fuse XTH100 (it is resettable polymeric positive temperature coefficient
fuse) has to be kept below 85°C to prevent false triggering. 85°C is max guaranteed temperature for
the fuse not to trip at ~0.6A. Max spec output current is only 0.5A.
*4)
- 50mm above surface, orientation A (see Application Note) no additional coldplate
- only main output is loaded (no load on fan out)
*5)
- U chasses or Baseplate fixed on a coldplate (system chassis), orientation A (see Application Note)
- Temperature of CUS150M chassis or Baseplate was less then ambient + 6°C
- only main output is loaded (no load on fan out)
