Precautions For Use:
Storage time:
1. Calculated shelf life before opening is 12 months at < 30°C and < 90% relative humidity (RH)
2. After bag is opened, devices which will be subjected to reflow soldering or other high
temperature processes must be
a) Assemblied within 168 hours in an environment of ≦ 30°C / 60% RH, or
b) Stored at ambient of 10% RH or less
3. Devices are required baking before assembly if:
a) Humidity Indicator Card reads >10% (for level 2a -5a)
or >60% (for level 2) at ambient temperature 23 ±5°C
b) 2.a) or 2.b) doesn't meet
4. If baking is required, devices should be baked for >24 hours at 60±5°C.Performing baking only once,
and using the baked devices within 72 hours.
Drive Method:
LED is a current operated device, and therefore, requirer some kind of current limiting incorporated into
the driver circuit. This current limiting typically takes the form of a current limiting resistor placed in series
with the LED.
Consider worst case voltage variations than could occur across the current limiting resistor. The forwrd
current should not be allowed to change by more than 40% of its desired value.
Circuit model A
Circuit model B

LED
(A) Recommended circuit.
(B) The difference of brightness between LED could be found due to the VF-IF characteristics of LED.
Cleaning:
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED.
ESD(Electrostatic Discharge):
Static Electricity or power surge will damage the LED. Use of a conductive wrist band or anti-electrosatic
glove is recommended when handing these LED. All devices, equipment and machinery must be properly
grounded.
