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.
