Ref.CE-P598 03/10 SPECIFICATIONS 8/9 Precautions 1. Avoid the application of any stress to the lens portion. 2. Avoid any contact by a sharp metal nail or other materials with the lens portion. Resin portion (Shaded area) M3screw (Insulation) Recommended torque : 0.6~0.8N-m Spring washer (≦ ƒΣ6mm) Plane washer ( ≦ƒΣ6mm) 12.64 mm 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. Thermal conductive silicon grease (Insulation paste) 13.08 Outer heat sink Recommended installation screw pitch 4. Thermal conductive silicone grease should be applied to the whole rear surface so that this product can dissipate heat as a whole. However, the use of insulating paste is strongly recommended in order to avoid short circuit. This product could be bent during the clamping operation if heat grease in sheet form is used. For this reason, it is recommended that grease in paste form is used. In addition, sufficient insulation should be established between heat sink area of LED package and surface of fixture. (*surface of fixture: exterior of instrument used for dielectric strength test in Electrical Appliance and Material Safety Law.) 5. 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=Max.1mA No-lighting in entire block making up parallel circuit is unacceptable L251 consists of three blocks.

Ref.CE-P598 03/10 SPECIFICATIONS 9/9 Precautions (continued) 6. Please be aware that this product should not come into contact with any other parts in assembled status. 7.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. 8. 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). 9. Recommended soldering - Soldering operation should be performed within 3.5 seconds per land using a soldering iron of 40W or lower. The temperature of a soldering iron should be adjusted 350C or lower. - No external force is applied to sealing resin during soldering operation. - Please do not handle a product until it returns to a normal temperature. Note: This product is not adaptable to reflow process. 10. Other - This product complies with RoHS directives. - This product is intended for the application in general electronic devices (such as office automation equipment, communication devices, audio-video equipment, home electrical appliances, measurement hardware and others). In cases where this product is used for the applications that requires high reliability or could directly affect human life or health due to failure or malfunction (aerospace hardware, medical equipment, atomic control equipment and others), please consult with our sales representatives beforehand. - Our warranty does not cover situations where this product undergoes secondary fabrication such as changes in shape. - An agreement of formal product specifications is required prior to mass production. - The specifications and appearance of this product are subject to change without advanced notice.
