Notes :

1. All dimensions in millimeters

 

Notice

 

1. In order to avoid absorption of moisture, it is recommended that the products are stored in the dry box (or desiccators ) with a desiccants. Alternatively the following environment is recommended:

 

Storage temperature : 5°C~30°C Humidity:60% HR max.

 

2. If the storage conditions are of high humidity the product should be dried before use.

 

Recommended drying conditions: 12 hours at 60°C±5°C.

 

3. Any mechanical force or any excess vibration should be avoid during the cooling process after soldering.

 

4. Reflow rapidly cooling should be avoided.

 

5. Components should not be mounted on distorted Printed Circuit Boards.

 

6. Devices should not contact with any types of fluid, such as water , oil , organic solvents…. etc.

 

7. The maximum ambient temperature should be taken into consideration when determining the operating current.

 

8. Devices should be soldered within 7 days after opening the moisture-proof packing.

 

9. Repack unused product in anti-moisture packing, fold to close any opening and store in a dry place.

 

10. The appearance and specifications of devices may be modified for improvement without notice.

 

11. ESD Precautions Static Electricity and surge damages LEDs. It is recommended that wrist bands or anti-electrostatic gloves be used when handing the LEDs . All devices, equipment and machinery should be properly grounded.

 

12. This product must be driven by constant power supplier
