esd(electrostatic discharge): static electricity or power surge will damage the led. use of a c onductive wrist band or anti-electrosatic glove is recommended when handing these led. all devices, equipment and machinery must be properly grounded. cleaning: use alcohol-based cleaning solvents such as isopropyl alc ohol to clean the led. (a) recommended circuit. (b) the difference of brightness between led could be f ound due to the vf-if characteristics of led. circuit model a led circuit model b led precautions for use: storage time: 1.the operation of temperatures and rh are : 5 j ~35 j ,rh60%. 2.once the package is opened, the products s hould be used within a week. otherwise, they should be kept in a damp proof box with descanting agent. considering the tape life, we suggest our customers to use our pr oducts within a year(from production date). 3.if opened more than one week in an atmos phere 5 j ~ 35 j ,rh60%, they should be treated at 60 j? 5 j fo r 15hrs. drive method: led is a current operated device, and therefore, require r some kind of current limiting incorporated into the driver circuit. this current limiting typically takes the form of a current limiting resistor placed in series with the led. consider worst case voltage variations than could occur across the current limiting resistor. the forwrd current should not be allowed to c hange by more than 40 % of its desired value. ligitek electronics co.,ltd. property of ligitek only page 12/13 part no.
