lite - on technology corporation p r o p e r t y o f l i t e - o n o n l y ca u tion s 1. application limitation the leds described here are intended to be used for ordinary electronic equipment (such as office equipment, communication equipment and household application.) c onsult liteons sales in advance for information on application in which exceptional quality and reliability are required, particularly when the failure or malfunction of the leds may directly jeopardize life or health (such as airplanes, automobile s, traffic control equipment, life support system and safety devices). 2. storage after being shipped from liteon the leds should be kept at 30c or less and 70%rh or less. the leds should be used within 3 months. they can be stored for a year in a sealed container with a nitrogen atmosphere and moisture absorbent material. please avoid rapid transitions in ambient temperature in high humidity environments where condensation may occur. 3. cleaning use alcohol - based cleaning solvents such as isopropyl alcohol to clean the led. 4. forming & mounting when forming a lead, the leads should be bent at a point at least 3mm from the base of epoxy bulb. do not use the base of the leadframe as a fulcrum during forming. lead forming must be done before soldering at normal temperature. when mounted through hole type led lamp, avoid the occurrence of residual mechanical stress due to clinching. 5. soldering when soldering, leave a minimum of 2mm clearance from the resin to the sol dering point. dipping the resin into the solder must be avoided. do not apply any stress to the lead frame during soldering while the led is at high temperature. recommended soldering condition soldering iron wave soldering temperature sold ering time 300c max. 3 sec. max. (one time only) pre - heat pre - heat time solder wave soldering time 100c max. 60 sec. max. 260c max. 10 sec. max. * the material of hook type housing is very sens i ti ve of soldering temperature. any increase of soldering temperature might serio us ly result in serious melting of the housing. 6. drive method led, a current operated device, requires specific current limit incorporated into the driving circuit. the current control can be achieved by using a resist or in series with the led. in order to prevent to exceed the allowed value of 40% over desired forward current, the resistor should be well chosen for possible voltage variation. two possible circuit designs are shown below. the circuit a is recommended, a nd the circuit b will probably result in uneven brightness between leds because of the vf - if characteristics of leds. circuit model a circuit model b pa rt no. : LTL307JGT page : 5 of 6 bns - od - c131/a4 led led
