NJL5902R
COBP PHOTO REFLECTOR
„ GENERAL DESCRIPTION
The NJL5902R is the compact surface mount type photo reflector in which Lead (Pb)-free reflow soldering permitted (260°C,
2times). The NJL5902R reduced to the operating dark current of 1/6 compared with our conventional products/NJL5901AR, and
has realized the high S/N ratio in the combination of the high output LED and a high sensitivity Si photo-transistor.

2) Reflow Method (In case of infrared heating)
The temperature profile is same as the above
Avoid direct irradiation to the plastic package because it may absorb the Infrared Radiation and its surface
temperature will be higher than the lead.
3) The other method
Avoid rapid heating up like dipping the devices directly into the melting solder or vapor phase method (VPS).
Solder the device in short time as soon as possible.
If the device is heated and kept in high temperature for longer time, its reliability would be affected.
2. Cleaning
Avoid washing the device after soldering by reflow method.
3. Attention in handling
1)
2)
3)
4)
Treat not to touch the lens surface.
Avoid dust and any other foreign materials on the lens surface such as paint, bonding material, etc.
Never to apply reverse voltage (VEC) of more than 6V on the photo transistor when measuring the characteristics or
adjusting the system. If applied, it causes to lower the sensitivity.
When mounting, special care has to be taken on the mounting position and tilting of the device because it is very
important to place the device to the optimum position to the object.
4. Storage
Mount the device as soon as possible after opening the envelope. In order to prevent from degradation by the moisture at
the reflow process, the device is contained in damp proof packaging.
