Maximum ratings are those values beyond which device damage can occur.  
Maximum ratings applied to the device are individual stress limit values (not  
normal operating conditions) and are not valid simultaneously. If these limits  
are exceeded, device functional operation is not implied, damage may occur  
and reliability may be affected.  
1. FR−5 = 3.5 X 1.5 inches, using the minimum recommended footprint.  
2. Thermal Resistance measurement obtained via infrared Scan Method.  
**The “T1” suffix refers to an 8 mm, 7 inch reel.  
The “T3” suffix refers to an 8 mm, 13 inch reel.  
†For information on tape and reel specifications,  
including part orientation and tape sizes, please  
refer to our Tape and Reel Packaging Specifications
