page 6/7 part no. le9553/tr1 precautions for use: storage time: 1.the operation of temperatures and rh are : 5 ~35 ,rh<60%. 2.once the package is opened, the products should 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 products within a year(from production date). 3.if opened more than one week in an atmosphere 5 ~ 35 ,rh<60%, they should be treated at 60 5 fo r 15hrs. ligitek electronics co.,ltd. property of ligitek only circuit model b led circuit model a led (a) recommended circuit. (b) the difference of brightness between led could be found due to the vf-if characteristics of led. cleaning: use alcohol-based cleaning solvents such as isopropyl alcohol to clean the led. esd(electrostatic discharge): static electricity or power surge will damage the led. use of a conductive wrist band or anti-electrosatic glove is recommended when handing these led. all devices, equipment and machinery must be properly grounded. drive method: led is a current operated device, and therefore, requirer 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 change by more than 40% of its desired value.
