CAUTIONS 
1. Application  
The LEDs described here are intended to be used for ordinary electronic equipment (such as office 
equipment, communication equipment and household applications).Consult Liteon’s Sales in advance 
for information on applications in which exceptional reliability is required, particularly when the failure 
or malfunction of the LEDs may directly jeopardize life or health (such as in aviation, transportation, 
traffic control equipment, medical and life support systems and safety devices). 
2. Storage 
The storage ambient for the LEDs should not exceed 30°C temperature or 70% relative humidity. 
It is recommended that LEDs out of their original packaging are IR-reflowed within one week. 
For extended storage out of their original packaging, it is recommended that the LEDs be stored in a 
sealed container with appropriate desiccant, or in a desiccators with nitrogen ambient.  
LEDs stored out of their original packaging for more than a week should be baked at about 60 deg C 
for at least 24 hours before solder assembly. 
3. Cleaning 
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary. 
4. Soldering
Recommended soldering conditions: 
Reflow soldering 
Wave Soldering 
Soldering iron 
Pre-heat

5. Drive Method 
An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs 
connected in parallel in an application, it is recommended that a current limiting resistor be incorporated 
in the drive circuit, in series with each LED as shown in Circuit A below.

(A) Recommended circuit. 
(B) The brightness of each LED might appear different due to the differences in the I-V characteristics 
of those LEDs. 
6. ESD (Electrostatic Discharge) 
Static Electricity or power surge will damage the LED.  
Suggestions to prevent ESD damage: 
Use of a conductive wrist band or anti-electrostatic glove when handling these LEDs. 
All devices, equipment, and machinery must be properly grounded. 
Work tables, storage racks, etc. should be properly grounded. 
Use ion blower to neutralize the static charge which might have built up on surface of the LED’s 
plastic lens as a result of friction between LEDs during storage and handling.
