Precaution for Use

(1) Storage

To avoid the moisture penetration, we recommend storing Z5 Series LED in a dry box with a

desiccant . The recommended storage temperature range is 5℃ to 30℃ and a maximum humidity of

RH50%.

(2) Use Precaution after Opening the Packaging

Use SMT techniques properly when you solder the LED as separation of the lens may affect the light

output efficiency.

Pay attention to the following:

a. Recommend conditions after opening the package

- Sealing / Temperature : 5 ~ 40℃ Humidity : less than RH30%

b. If the package has been opened more than 4 weeks (MSL 2a) or the color of

the desiccant changes, components should be dried for 10-12hr at 60±5℃

(3) Do not apply mechanical force or excess vibration during the cooling process to normal

temperature after soldering.

(4) Do not rapidly cool device after soldering.

(5) Components should not be mounted on warped (non coplanar) portion of PCB.

(6) Radioactive exposure is not considered for the products listed here in.

(7) Gallium arsenide is used in some of the products listed in this publication. These products are

dangerous if they are burned or shredded in the process of disposal. It is also dangerous to drink the

liquid or inhale the gas generated by such products when chemically disposed of.

(8) This device should not be used in any type of fluid such as water, oil, organic solvent and etc.

When washing is required, IPA (Isopropyl Alcohol) should be used.

(9) When the LED are in operation the maximum current should be decided after measuring the

package temperature.

(10) The appearance and specifications of the product may be modified for improvement without

notice.

(11) Long time exposure of sunlight or occasional UV exposure will cause lens discoloration.
