Notes: 
1.  RMA flux is recommended.  Duration can be extended to 10 seconds maximum when flow soldering.  A maximum of 20 grams force 

may be applied to the leads when soldering. 

2.  Derate linearly 1.33 mW/° C above 25° C. 
3. E

E(APT)

 is a measurement of the average apertured radiant energy incident upon a sensing area 0.180” (4.57 mm) in diameter 

perpendicular to and centered on the mechanical axis of the lens and 0.653” (6.60 mm) from the lens tip.  E

E(APT)

 is not necessarily 

uniform within the measured area.
