Infrared Light Emitting Diodes
LN189S
GaAlAs Infrared Light Emitting Diode
Light source for distance measuring systems
Features
High-power output, high-efficiency : PO = 5.5 mW (typ.)
Fast response and high-speed modulation capability : tr, tf =20 ns (typ.)
Infrared light emission close to monochromatic light : λP = 880 nm(typ.)
Narrow direcivity using spherical lenses; works well with optical
systems in auto focus systems

Precautions for Use
[Airtightness] This product is not structured to provide a complete air seal. Therefore it cannot be immersed in solutions for
purposes such as boiling tests or ultrasonic cleaning.
[Ability to withstand soldering heat]
The package of this product contains thermoplastic resin which has a limited ability to withstand heat. Therefore
this product cannot be put through automated soldering operations in which the ambient temperature exceeds
the specified temperature. The recommended soldering conditions are as follows.
]· Temperature of soldering iron tip : 260˚C or less
· Soldering time
: 5 seconds or less
or
: 300˚C or less
: 1 second or less
· Soldering position
: At least 2 mm away from lead base
[Ability to withstand chemicals]
If the transparent case requires cleaning, wipe it lightly using ethyl alcohol, methyl alcohol, or isopropyl alcohol.
If you plan to use other solvents, carefully check to make sure there are no problems such as a misshapen case or
a change in the condition of the case material.
