Notes:
1) The COB is tested in pulsed condition at rated test current (10 ms pulse width) and rated temperature (Tj = Tc = Ta = 25 °C)
2) Samsung maintains measurement tolerance of: forward voltage = ±5 %, CRI = ±1
3) Max Tc=105

Precautions in Handling & Use
1)
This device should not be used in any type of fluid such as water, oil, organic solvent, etc. When cleaning is required, IPA
is recommended as the cleaning agent. Some solvent-based cleaning agent may damage the silicone resins used in the
device.
2)
LEDs must be stored in a clean environment. If the LEDs are to be stored for three months or more after being shipped
from Samsung, they should be packed with a nitrogen-filled container (shelf life of sealed bags is 12 months at
temperature 0~40 ºC, 0~90 % RH).
3)
After storage bag is opened, device subjected to soldering, solder reflow, or other high temperature processes must be:
a. Mounted within 672 hours (28 days) at an assembly line with a condition of no more than 30 ºC / 60 % RH, or
b. Stored at 60 % at 23 ± 5 ºC.
6)
Devices must be baked for 1 hour at 60 ± 5 ºC, if baking is required.
7)
The LEDs are sensitive to the static electricity and surge current. It is recommended to use a wrist band or antielectrostatic glove when handling the LEDs. If voltage exceeding the absolute maximum rating is applied to LEDs, it may
cause damage or even destruction to LED devices. Damaged LEDs may show some unusual characteristics such as
increase in leakage current, lowered turn-on voltage, or abnormal lighting of LEDs at low current.
8)
VOCs (Volatile Organic Compounds) can be generated from adhesives, flux, hardener or organic additives used in
luminaires (fixtures). Transparent LED silicone encapsulant is permeable to those chemicals and they may lead to a
discoloration of encapsulant when they exposed to heat or light. This phenomenon can cause a significant loss of light
emitted (output) from the luminaires. In order to prevent these problems, we recommend users to know the physical
properties of materials used in luminaires and they must be carefully selected.
9)
The resin area is very sensitive, please do not handle, press, touch, rub, clean, or pick by with tweezers on it. Instead,
please pick at the handling area as indicated below.
