(1) 1. Handling with care for this product
-Both the light emitting area and white dam over the light emitting area is composed of resin
materials.
Please avoid the resin area from being pressed, stressed, rubbed, come into contact with sharp
metal nail
(e.g. edge of reflector part) because the function, performance and reliability of this product
are negatively impacted.
(2) Countermeasure against static electricity
-Handling of this product needs countermeasures against static electricity
because this is a semiconductor product.
-Please take adequate measures to prevent any static electricity being produced
such as the wearing of a wristband or anti-static gloves when handling this product.
-Every manufacturing facility in regard to the product (plant, equipment, machine, carrier machine
and conveyance unit) should be connected to ground and please avoid the product to be electric-charged.
-ESD sensitivity of this product is over 1000V (HBM, based on JEITA ED-4701/304).
-After assembling the LEDs into your final product(s), it is recommended to check
whether the assembled LEDs are damaged by static electricity (electrical leak phenomenon) or not.
-It is easy to find static damaged LED dies by a light-on test with the minimum current value.
(3) Caution of product assembly
-Regarding this product assembling on the heat sink, it is recommended to use M3 screw.
It might be good for screw tightening on the heat sink to do temporary tightening and final tightening.
In addition, please don’t press with excess stress on the product.
-The condition of the product assembling on the heat sink and the control of screw tightening torque
needs to be optimized according to the specification of the heat sink.
-Roughness, unevenness and burr of surface negatively impact thermal bonding
between the product and heat sink and increase heat thermal resistance between them.
Confidence of thermally and mechanical coupling between the product and heat sink are confirmed
by checking the mounting surface and measuring the case temperature of the product.
-In order to reduce the thermal resistance at assembly, it might be good to use
TIM (Thermal Interface Material) on whole contact surface of the product.
In case of using thermal grease for the TIM, it might be good to be applied uniformly
on the contact surface of the product. In case of using thermal sheet for the TIM,
it might be good to make sure that the product is NOT strained by stress
when the screws are tightened for assembly.

(4) Thermal Design
-The thermal design to draw heat away from the LED junction is most critical parameter
for an LED illumination system. High operating temperatures at the LED junction adversely affect
the performance of LED’s light output and lifetime. Therefore the LED junction temperature should
not exceed the absolute maximum rating in LED illumination system.
(Note : Refer to 4-(1) Performance)
-The LED junction temperature while operation of LED illumination system depends upon
thermal resistance of internal LED package (Rj-c), outer thermal resistances of LED package,
power loss and ambient temperature. Please take both of the thermal design specifications
and ambient temperature conditions into consideration for the setting of driving conditions.
-For more information, please refer to application note "Thermal Management CLL040 Series".
(5) Driving Current
-A constant current is recommended as an applying driving current to this product.
In the case of constant voltage driving, please connect current-limiting resistor to each products in series
and control the driving current to keep under the absolute maximum rating forward current value.
-Electrical transient might apply excess voltage, excess current and reverse voltage to the product(s).
They also affect negative impact on the product(s) therefore please make sure that no excess voltage,
excess current and reverse voltage is applied to the product(s)
when the LED driver is turn-on and/or turn-off.
-For more information, please refer to application note "Driving".
(6) Lighting at a minimum current value
- The minimum current value of all LED dice lighting is 90 mA.
(The minimum current of each product is calculated and stated on the premise of 5mA dice)
-In a case where the lowest current is applied to the product,
some of LED dice in the product might look different in their brightness
due to the individual difference of the LED dice, and they are not failed.
(7) Electrical Safety
-This product is designed and produced according to IEC 62031:2008
(IEC 62031:2008 LED modules for general lighting. Safety specification)
-Dielectric voltage withstand test has been conducted on this product to see any failure
after applying voltage between active pads and aluminum section of the product,
and to pass at least 500V.
-Considering conformity assessment for IEC62031:2008, almost all items of the specification
depend upon your final product of LED illumination system.
Therefore, please confirm with your final product for electrical safety of your product.
As well, the products comply with the criteria of IEC62031:2008 as single LED package.

(9) Eye Safety
-The International Electrical Commission (IEC) published in 2006 IEC 62471
”2006 Photobiological safety of lamps and lamp systems ” which includes LEDs within its scope.
When sorting single LEDs according to IEC 62471, almost all white LEDs can be classified
as belonging to either Exempt Group (no hazard) or Risk Group 1 (low risk).
-However, Optical characteristics of LEDs such as radiant flux,
spectrum and light distribution are factors that affect the risk group determination of the LED,
and especially a high-power LED, that emits light containing blue wavelengths,
might have properties equivalent to those of Risk Group 2 (moderate risk).
-Great care should be taken when directly viewing an LED that is driven at high current,
has multiple uses as a module or when focusing the light with optical instruments,
as these actions might greatly increase the hazard to your eyes.
-It is recommended to regard the evaluation of stand-alone LED packages as a reference
and to evaluate your final product.
(10) This product is not designed for usage under the following conditions.
If the product might be used under the following conditions, you shall evaluate its effect
and appropriate them. In places where the product might:
-directly and indirectly get wet due to rain and/or at place with the fear.
-be damage by seawater and/or at place with the fear
-be exposed to corrosive gas (such as Cl2, H2S, NH3, SOx, NOx and so on) and/or at place with the fear.
-be exposed to dust, fluid or oil and/or at place with the fear.
(8) Recommended soldering Condition (This product is not adaptable to reflow process.)
-For manual soldering
Please use lead-free soldering.
Soldering shall be implemented using a soldering bit at a temperature lower than 350C°,
and shall be finished within 3.5 seconds for one land.
No external force shall be applied to resin part while soldering is implemented.
Next process of soldering should be carried out after the product has return to ambient temperature.
-For soldering correction
Regarding soldering correction, above conditions shall be applied.
Contacts number of soldering bit should be within twice for each terminal as a correction.
* Citizen Electronics cannot guarantee if usage exceeds these recommended conditions.
Please use it after sufficient verification is carried out on your own risk if absolutely necessary.
