7 / 12 page [Data Sheet] 1.Storage If the product is heated during the reflow under the condition of hygroscopic state, it may vaporize and expand which will influence the performance of the product. Therefore, the package is waterproof. Please use the product following the conditions: ・Using Conditions ・Baking Bake the product in case of below: ①The expiration date is passed. ②The color of indicator (silica gel) turned from blue to colorless or from green to pink. ・Baking Conditions 2.Application Methods 2-1.Precaution for Drive System and Off Mode Design the circuit without the electric load exceeding the ABSOLUTE MAXIMUM RATING that please do not apply voltage neither forward nor reverse. Especially, for the products with the Ag-paste used in the die bonding, there’s high possibility to cause electro migration and result 2-2.Derating The Derating Characteristics are based on the lifetime of luminous intensity and assumption of degradation & color change of sealing resin or reflector. About its reliability, 2-3.Operation Life Span There’s possibility for intensity of light drop according to working conditions and environments (applied current, surrounding temperature and humidity, corrosive gases), please call our Sales ①Longtime intensity of light life ②On mode all the time 2-4.Applied Stress on Product The top of the LED is very soft, which the silicon resin is used as sealing resin. Therefore, please pay attention to the overstress on it which may influence its reliability. 2-5.Usage The Product is LED. We are not responsible for the usage as the diode such as Protection Chip, ・Reel and embossed tape are easy to be deformed when baking, Please storing in the airtight container ①Before using 5〜30℃ 30〜70%RH Within 1 year from Receiving Storage with waterproof package ②After opening package Remark so please try not to apply stress on it. ・Recommend bake once. 5〜30℃ Below 70%RH Within 72h with our desiccant (silica gel) (Even if the product is within the expiration date.) 60±3℃ 40〜48h Below 20%RH [SML-Z14x(C) series] ■Precaution (Surface Mount Device) Rectifier, Switching and so on. Temperature Time Humidity ・Bake products in reel. Classification Temperature Humidity Expiration Date Remark applies on the products. If drive by constant voltage, it may cause current deviation of the LED and result in deviation of luminous intensity, so we recommend to drive by constant current. (Deviation of VF Value will cause deviation of current in LED.) Furthermore, for off mode, in function failure. please evaluate its using conditions and environment and use it after confirmed there is no problem. staffs for inquiries about the concerned application below. ________________________________________________________ www.rohm.com ©2016 ROHM Co., Ltd.
