Handling Precautions
* * * Soldering must be performed under the stopper. When forming the leads, bend each lead under the 5 mm of package body. Soldering must be performed after the leads have been formed. The radiant intensity decrease over time due to current flowing in the infrared LED. When designing circuits, the device must take into account the change in radiant intensity over time. The change in radiant intensity is equal to the reciprocal of the change in LED infrared optical output. IE (t) P o (t) = IE (0) P o (0)
