deep uv led

340nm uv led


Precaution for use:
1.storage
To avoid moisture penetration,we recommend storing UV LEDs in a dry box with a desiccant.
The recommended storage temperature range is 5deg to 30deg and a maximum humidity of 50%.
Use Precaution after opening the packaging.

Affect the light output efficiency.
Pay attention to the following:
a.Soldering should be done as soon as possible after opening the package.
b.Required conditions after opening the package.
-Sealing
-Temperature:5-30s Humidity:less than 30%.

Affect the proper function of the LEDs.
1)Don‘t apply mechanical force or excess vibration during the cooling process to normal temperature after soldering.
2)Don‘t rapidly cool device after soldering.
3)Components shouldn‘t be mounted on warped(non coplanar) portion of PCB.
4)Radioactive exposure isn‘t considered for the products listed here in.
5)This device shouldn‘t be used in any type of fluid such as water,oil,organic solvent and etc.
6)when washing is required,IPA(Isopropyl Alcohol) should be used.
7)when the LEDs are in operation the maximum current should be decided after measuring the package temperature.
8)LEDs must be stored properly to maintain the device,if the LEDs are stored for 3 months or more after being shipped from SSC,a sealed container with a nitrogen atmosphere should be used for storage.
8)The appearance and specifications of the product maybe modified for improvement without notice.
9)the slug is isolated from anode electrically,so we recommand that you don‘t isolate the heat sink.
10)Attaching LEDs,don‘t use adhesives that outgas organic vapor.
