(deviation of vf value will cause deviation of current in led.) furthermore, for off mode, please do not apply voltage neither forward nor reverse. especially, for the products with the ag-paste used in the die bonding, theres high possibility to cause electro migration and result in function failure. 2-2. operation life span theres possibility for intensity of light drop according to working conditions and environments (applied current, surrounding temperature and humidity, corrosive gases), please call our sales staffs for inquiries about the concerned application below. 1 longtime intensity of light life 2 on mode all the time 2-3.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. 2-4.usage the product is led. we are not responsible for the usage as the diode such as protection chip, rectifier, switching and so on. downloaded from: http:///
