Product Description
Top led
Absolute Maximum Ratings at TA=25℃
Electrical Optical Characteristics at TA=25℃
Note: 1.Luminous intensity is measured with a light sensor and filter combination that approximates CIE (Commission International Dd L Eclairage)eyeresponse curve.
2. θ1/2 is the off-axis angle at which the luminous intensity is half the axial
luminous intensity.
3. The dominant wavelength,λd is derived from the CIE chromaticity diagram and representsthe single wavelength which defines the color of the device.
4.The Iv guarantee should be added ± 15%.

NOTES
1.All dimensions are in millimeters .
2.Tolerance is ±0.1mm unless otherwise noted.
3.Protruded resin under flange is 1.0mm max.
4.Lead spacing is measured where the leads emerge from the package.
5.Specifications are subject to change without notice.
CAUTIONS
1.Application
The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment,communication equipment and household applications).Consult MLS's Sales in advance for informa- tion. on applications in which exceptional reliability is required,particularly when the failure or malfunction. of the LEDs may directly jeopardize life or health(such as in aviation ,transportation, traffic control eq- uipment,medical and life support systems and safety devices)
2.Storage
The storage ambient for the LEDs should not exceed 30℃ temperature or 60% relative humidity.It is recommended that LEDs out of their original packaging are used within three months. For extended storage out oftheir original packag ing,it is recommended that the LEDs be stored in asealed container with appropriatedesiccant or in desiccators with ni-
trogen ambient.
3. Cleaning
Use alcohol-based cleaning solvent such as isopropyl alcohol to clean the LEDs if necessary.
4.Lead Forming & Assembly
Do not use the base of the lead frame as a fulcrum during forming. Lead forming must be done before soldering,at normal temperature.
During assembly on PCB, use minimum clinch force possible to avoid excessive mechanical stress.
5.Soldering
Do not apply any external stress to the lead frame during soldering while the LED is at high temperature.Recommend-ed soldering conditions:
Soldering iron | Wave soldering | ||
Temperature Soldering time | 300℃ Max 3 sec.Max (one time only) | Pre-heat Pre-heat time Solder wave Soldering time | 180℃ Max 120sec.Max 260℃ Max 10sec.Max |
Note:Excessive soldering temperature and/or time might result in deformation of the LED lens or catastrophic failure of the LED.
6.Drive Method
An LED is a current-operated device,In order to ensure intenity uniformity on multiple LEDs connected in parallel in
an application,it is recommended that a current limiting resistor beincorporated in thedrive circuit,in serieswith each-
LED as shown in Circuit A below.
7.Protect Of ESD
Since the device is static sensitive,it is requested that anti-static measures should be taken on human body,all devices
(including soldering iron) and equipment,machinery,desk and ground.
