Handling Precautions

• Soldering must be performed under the stopper.

• When forming the leads, bend each lead at least 5 mm from the package body. Soldering must be performed

after the leads have been formed.

• The radiant intensity decreases over time due to current flowing in the infrared LED. When designing circuits,

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:
