3. Precautions for product assembly

-When the LED package is attached to the heat sink by M3 screws, please be careful not to apply

Recommended installation screw pitch

13.513.5

A minimum current value of lighting of all dice is 10mA.

When a minimum current is applied, LED dice may look different in their brightness due to

the individual difference of the LED element, and it is not a failed product.

8. Please be aware that this product should not come into contact with any other parts

in assembled status.

9. Drive circuit

- A constant current circuit is recommended as a drive circuit.

And when two or more LED packages are connected, the series connection

between each package is recommended.

- Please design a circuit that prevents any reverse voltage (excess current) from being

applied to this product instantaneously when the circuit is ON or OFF.

10. Heat generation

- As this product is designed with consideration of the heat release property of module,

a heat release design is required to use this product efficiently.

Please ensure that heat generation is not in excess of the absolute maximum rating.

(Refer to 4-1 Performance)

- Factors responsible for an increase in temperature include heat generation attributed to

ambient temperature conditions or power dissipation. Thus, drive conditions should be

taken into consideration, depending on ambient temperature (Ta).

11. Recommended soldering condition (This product is not adaptable to reflow process)

- Manual soldering

- Soldering shall be implemented using a soldering bit of 40W or less with a temperature

350°C or less within 3.5 seconds for one land.

(Recommended condition in a case of lead-free solder condition)

- No external force shall be applied to resin part during soldering.

- Next process of soldering should be carried out after the product has returned to ambient temperature. - For soldering correction

- Regarding soldering correction, above conditions shall be used.

- Contacts number of soldering bit should be within twice for each terminal as a correction.

* Citizen Electronics cannot guarantee if usage exceeds this recommended conditions.

Please use it after sufficient verification is carried out on your own risk if necessary.

Symbol CITILED12. Eye Safety

- The International Electrical Commission (IEC) published in 2006 IEC 62471

”2006 Photobiological safety oflamps and lamp systems” which includes LEDs within its scope.

When sorting single LEDs according to IEC 62471, most white LEDs can be classified as belonging to

either Exempt Group or Risk Group 1.

- 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, may have properties equivalent to those of Risk Group 2.

- 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 may 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 the customer's final product.

13. The use of Class 2 power supply is assumed for this product.

14. If the product might to be used under the following conditions, the customer must evaluate

its approproateness them. This product is not designed for use under the following conditions.

in places where the product might:

- get wet due to rain

- suffer from damage caused by salt.

- be exposed to corrosive gas such as Cl, H2S, NH3, SO2, Nox and so on.

- be exposed to dust, fluid or oil.
