Avoid the application of any stress to the resin portion. 2. Avoid any contact by a sharp metal nail or other materials with the resin portion. Resin portion (Shaded area) 3. This product should be secured firmly by fastening an M3 screw on both sides of the product. Please be careful not to apply any stress to the product during the clamping operation. As the connection status could vary depending on materials of outer heat sink, please check thoroughly. M3screw (Insulation) 11.0mm Spring Washer ( ≦φ6mm) Plane washer ( ≦φ6mm) Thermal conduction materials (Insulation) Outer heart sink 19.5mm Recommended installation screw pitch 4. Insulation between the terminal section and the heat sink section of the LED is not covered by warranty. With regard to insulation after this product has been assembled in an apparatus, preventive action should be carried out by the customer. 5. For fixing this product to the outer heat sink, heat grease should be applied to the whole rear surface so that the product can dissipate heat as a whole. Please pay attention to avoid product deformation when conducting the clamping operation with heat grease in sheet form. 6. Handling of static electricity - These products are sensitive to static electricity charge. Please take measures to prevent any static electricity being produced such as the wearing of a wristband or anti-static gloves when handling this product. - All devices, equipment and machinery must be properly grounded. It is recommended that precautions be taken against surge voltage to the equipment that mounts the LEDs. - ESD sensitivity of this product is 1000V (HBM, based on JEITA ED-4701/304). - When inspecting the final products in which LEDs were assembled, it is recommended to check whether the assembled LEDs are damaged by static electricity or not. - It is easy to find static-damaged LEDs by a light-on test. <Light-on test criterion> Judgmental criterion Condition IF=6mA/PKG No-lighting in entire block making up parallel circuit is unacceptable L234 consists of twelve blocks. Symbol CITILED Name CL-L234A-C18N1-C CITIZEN ELECTRONICS CO.,LTD. JAPAN Ref.CE-P1730 12/11 DATA SHEET 9/10 8. Precautions (continued) 7. Lighting at a low current A minimum current value of lighting of all dice is 30mA. When a minimal 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 - 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. 12. Other - This product complies with RoHS directives.
