LED diodes surface mount type smd 3528 multi color
Notes:
1. All dimension units are millimeters。
2. All dimension tolerance is ±0.2mm unless otherwise noted。
LED diodes surface mount type smd 3528 multi color
Notes:
1.Absolute maximum ratings Ta=25℃.
2.Tolerance of measurement of forward voltage±0.1V.
3.Tolerance of measurement of luminous intensity±15%.
4.Tolerance of measurement of the color coordinates is ±0.01
5. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.It use many parameters
that correspond to the CIE 1931 2°
Tolerance of measurement of angle is ±10 degree.
6.Caution in ESD: Static Electricity and surge damages the LED. lt is recommended to use a wrist band or
anti-electrostatic glove when handling the LED.All devices, equipment and machinery must be properly grounded.
7. The dominant wavelength λd is derived from the CIE chromaticity diagram and represents the single wavelength
which defines the color of the device.

(1) Storage
a.Recommended storage condition: at 5℃-30℃ or less and 60%RH and the storage life limits are 3 months.
b.If the LEDs are stored more then 3 months, they can be stored for a year in a sealed container with a nitrogen atmosphere
and moisture absorbent material.
c.Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where condensation can
occur.
(2) use
After this bag is opened ,devices that will be applied to infrared reflow,vapor-phase reflow,or equivalent soldering process
must be:
a.Completed within 24 hours;
b.Stored at less than 30% RH.
c.Devices require baking before mounting , if:
Don't conform to the above two points.
d.If baking is required, devices must be baked under below conditions:
12 hours at 60℃±3℃
(3) Static Electricity
a.Static electricity or surge voltage damages the LEDs.
b.It is recommended that a wristband or an anti-electrostatic glove be used when handling the LEDs.
c.All devices, equipment and machinery must be properly grounded.
d.It is recommended that measures be taken against surge voltage to the equipment that mounts the LEDs.
e.Damaged LEDs will show some unusual characteristics such as the leak current remarkably increases, the forward voltage
becomes lower, or the LEDs do not light at the low current.
Criteria: (VF>2.0V at IF=0.5mA)
(4) Heat Generation
a.Thermal design of the end product was most importance. Please consider the heat generation of the LED when making the
system design.
b.The thermal resistance of the circuit board and density of LED placement on the board, as well as other components was the
important factor affecting the coefficient of temperature increase per input electric power. It must be avoid intense heat
generation and operate within the maximum ratings given in the specification.
The operating current should be decided after considering the ambient maximum temperature of LEDs.
(5) Cleaning
a.It is recommended that isopropyl alcohol be used as a solvent for cleaning the LEDs. When using other solvents, it should
be confirmed beforehand whether the solvents will dissolve the resin or not. Freon solvents should not be used to clean the
LEDs because of worldwide regulations.
b.Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence of ultrasonic cleaning on the LEDs
depends on factors such as ultrasonic power and the assembled condition. Before cleaning, a pre-test should be done to
confirm whether any damage to the LEDs would occur.
(6) Soldering Condition for LED Lamps
a. Manual Soldering with a Soldering Iron
• Use of a soldering iron of less than 25 watts is recommended. The iron temperature must be kept below 315ºC and soldering
time no more than 2 seconds.
• The epoxy resin of an SMD LED should not contact the tip of the soldering iron.
• No mechanical stress should be exerted on the resin portion of an SMD LED during soldering.
• Handling of an SMD LED should be done only when the package has been cooled down to below 40ºC or less. This is to
prevent SMDLED failures due to thermal-mechanical stress during handling.
b. Reflow Soldering
