Note 1:

All data listed in the above graphs, except for derating data, has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.

Note 2:

Thermal derating graphs are developed in free air convection cooling of 40-60 LFM. (See Thermal Application Note)
