Precautions

• When removing flux with chemicals after soldering, clean only the leads on the soldering side; do not dip the

whole package for cleaning.

Chemicals remaining on an LED or photo transistor light emitter or receiver, if any, would have a bad influence

to the optical characteristics and it may severely lower the conversion efficiency.

• Care must be taken in relation to the environment in which the device is to be installed. Oil or chemicals may

cause the package to melt or crack.

• The device should be mounted on an unwarped surface.

• Conversion efficiency falls over time due to the current which flows in the infrared LED. When designing a

circuit, take into account this change in conversion efficiency over time. The ratio of fluctuation in conversion

efficiency to fluctuation in infrared LED optical output is 1:1.
