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.
