DCM300P280x500A40  
Electrical Specifications  
Specifications apply over all line, trim and load conditions, internal temperature TINT = 25ºC, unless otherwise noted. Boldface specifications apply over the  
temperature range of -40°C < TINT < 125°C for T grade and -55°C < TINT < 125°C for M grade.
