(refer to 4-1 performance) and when two or more led packages are connected, the series connection between each package is recommended. 350c or less within 3.5 seconds for one land. * 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. 10. heat generation data sheet 7. lighting at a low current (recommended condition in a case of lead-free solder condition) when a minimum current is applied, led dice may look different in their brightness due to - manual soldering applied to this product instantaneously when the circuit is on or off. - a constant current circuit is recommended as a drive circuit. - please design a circuit that prevents any reverse voltage (excess current) from being - factors responsible for an increase in temperature include heat generation attributed to - soldering shall be implemented using a soldering bit of 40w or less with a temperature please ensure that heat generation is not in excess of the absolute maximum rating. citizen electronics co.,ltd. japan citiled name CL-L251A-MC4L1-C ref.ce-p1001 03/11 r1(0711) 10/11 12. 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 leds can be classified as belonging to either exempt group or risk group 1. - 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. - in addition, led sources that were included within the scope of iec 60825-1 / edition 1.2 laser safety standard, published 2001 were removed from the scope of the iec 60825-1 / edition 2.0 revised 2007. - however, keep in mind that some countries and regions have adopted standards based on the iec laser safety standard iec 60825-1:2001 which includes leds within its scope. symbol data sheet - this product complies with rohs directives. 13. other citiled name CL-L251A-MC4L1-C citizen electronics co.,ltd. japan ref.ce-p1001 03/11 r1(0711) 11/11 such information, however, is subject to change without any prior notice. included in this document, business interruption and loss of data, and disclaims any and all express or implied warranties and for providing adequate designs and safeguards to minimize risk and avoid situations symbol data sheet 9. precautions with regard to product use 1. this document is provided for reference purposes only so that citizen electronics' products are used as intended. citizen electronics neither makes warranties or representations with respect to the accuracy or completeness of the information contained in this document nor grants any license to any intellectual property rights or any other rights of citizen electronics or any third party with respect to the information in this document. 2. all information included in this document such as product data, diagrams, charts, is current as of the date this document is issued. before purchasing or using any citizen electronics' products listed in this document, please confirm the latest product information with a citizen electronics' sales office, and formal specifications must be exchanged and signed by both parties prior to mass production. 3. citizen electronics has used reasonable care in compiling the information but citizen electronics assumes no liability whatsoever for any damages incurred as a result of errors or omissions in the information included in this document. 4. absent written signed agreement, except as provided in the relevant terms and conditions of sale for product, and to the maximum extent allowable by law, citizen electronics assumes no liability whatsoever, including without limitation, indirect, consequential, special, or incidental damages or loss, including without limitation, loss of profits, loss of opportunities, and conditions related to sale, use of product, or information, including warranties or conditions of merchantability, fitness for a particular purpose, accuracy of information, or no infringement. 5. though citizen electronics works continually to improve products' quality and reliability, products can malfunction or fail. customers are responsible for complying with safety standards in which a malfunction or failure of a product could cause loss of human life, bodily injury or damage to property, including data loss or corruption. in addition, customers are also responsible for determining the appropriateness of use of any information contained in this document such as application cases not only with evaluating by their own but also by the entire system. citizen electronics assumes no liability for customers' product design or applications. 6. please contact citizen electronics' sales office if you have any questions regarding the information contained in this document, or if you have any other inquiries. citiled name CL-L251A-MC4L1-C citizen electronics co.,ltd. japan ref.ce-p1001 03/11 r1(0711) |
