Nichia STSE-CC6130A
<Cat.No.061218>
7.CAUTIONS
(1) Cautions
· The devices are UV light LEDs.
The LED during operation radiates intense UV light,
which precautions must be taken to prevent looking directly at the UV light with unaided eyes.
Do not look directly into the UV light or look through the optical system.
When there is a possibility
to receive the reflection of light, protect by using the UV light protective glasses so that light should not
catch one’s eye directly.
· The caution label is attached to the moisture proof foil bag and cardboard box.

(2) Storage
· Storage Conditions
Before opening the package :
The LEDs should be kept at 30°C or less and 90%RH or less. The LEDs should be used within a
year.
When storing the LEDs, moisture proof packaging with absorbent material (silica gel)
is recommended.
After opening the package :
If unused LEDs remain, they should be stored in moisture proof packages, such as sealed containers
with packages of moisture absorbent material (silica gel).
It is also recommended to return the
LEDs to the original moisture proof bag and to reseal the moisture proof bag again.
· Nichia LED electrodes are gold plated. The silver surface may be affected by environments which
contain corrosive substances. Please avoid conditions which may cause the LED to corrode,
tarnish or discolor. This corrosion or discoloration may cause difficulty during soldering operations.
It is recommended that the User use the LEDs as soon as possible.
· Please avoid rapid transitions in ambient temperature, especially in high humidity environments where
condensation can occur.
(3) Heat Generation
· Thermal design of the end product is of paramount importance.
Please consider the heat generation
of the LED when making the system design. The coefficient of temperature increase per input
electric power is affected by the thermal resistance of the circuit board and density of LED placement
on the board, as well as other components. It is necessary to avoid intense heat generation and operate
within the maximum ratings given in this specification.
· Please decide on operating current volume according to LEDs’ ambient temperature and conduct heat
release treatment.
· The equation
1
indicates correlation between Tj and Ta, and the equation
2
indicates correlation
between Tj and Ts.
Tj=Ta + Rja W
1
Tj=Ts + Rjs W
2
Tj = Dice Temperature : °C, Ta = Ambient Temperature : °C, Ts = Solder Temperature : °C
Rja = Heat resistance from Dice to Ambient temperature : °C /W,
Rjs = Heat resistance from Dice to Ts measuring point : °C /W,
W = Inputting Power (I

· Maximum Tj shall be under 130°C. Keeping Tj less or equal to 100°C is recommended.
