8. Packing Specifications
8-1. Moisture-proof Packing
9/11
To prevent moisture absorption during transportation and storage, reels are packed in aluminum envelopes which contain a desiccant with a humidity indicator.
Aluminum envelop
Reel Polyester Zip fastener
Desiccant Label
8-2. Storage
To prevent moisture absorption, it is strongly recommended that reels (in bulk or taped) should be stored in the dry box (or the desiccator) with a desiccant as the appropriate storage place. If not, the following is recommended. Temperature: Humidity: 5~30C 60%RH max
The devices should be mounted as soon as possible after unpacking. If you store the unpacked reels, please store them in the dry box or seal them into the envelop again.

10. Designing precautions
11/11
(1) The current limiting resistor should be placed in the circuit so that is driven within its rating. Also avoid reverse voltage (over-current) applied instantaneously when ON or OFF. (2) When pulse driving current is applied, average current consumption should be within the rating. Also avoid reverse voltage applied when put off. (3) Recommended soldering pattern

Unit : mm
The above dimensions are not the one which guarantee the performance of mount ability. The use of the above pattern is recommended to use after deep study at your site. (4) When assembling the circuit board into the finished products, care must be taken to avoid the component parts from touching other parts. (5) When using multiple LEDs, it is required to connect a current limiting resistor on each path which the current flows to the LEDs. (ex-1) (ex-2) (ex-3)
