Precautions

Storage

• Before opening original package, it is recommended to store them in the following environment: Temperature:

5°C~30°C,Humidity: 85%RH max. When the inventory over 3 months,Should be done before treatment using

dehumidification, Temperature: 60°C/8 hours.

• 5~ 30˚C ; 60% after opening original package, the storage ambient for the LEDs should be in 5~30˚C temperature and

60% or less relative humidity.

• In order to avoid moisture absorption, it is recommended that the LEDs that out of the original package should be

stored in a sealed container with appropriate desiccant, or in desiccators with nitrogen ambient.

• The LEDs should be used within 168hrs (7days) after opening the package. Once been mounted, soldering should be

quick.

• If the moisture absorbent material (silica gel) has faded away or the LEDs stored out of original package for more than

168hrs (7 days), baking treatment should be performed using the conditions: 60˚C at least 24 hours.

Application

Rank Tolerance

REF / VF: ±0.02V

CAT / IV: ±10%

X / Y: ±0.005

Circuit model A

Circuit model B

• A LED is a current-operated device. The slight shift of voltage will cause big change of current, which will damage

LEDs. Customer should use resistors in series for the Over-Current-Proof.

• In order to ensure intensity uniformity on multiple LEDs connected in parallel in

an application, it is recommended to use individual resistor separately, as shown in Circuit A below. The brightness of

each LED shown in Circuit B might appear difference due to the differences in the I-V characteristics of those LEDs

• High temperature may reduce LEDs’ intensity and other performances, so keeping it away from heat source to get

good performance is necessary.

Soldering

• Reflow soldering should not be done more than 2 times.

• Manual soldering is only suggested on repair and rework. The maximum soldering temperature should not exceed

300˚C within 3 sec. And the maximum capacity of soldering iron is 30W in power.

• During the soldering process, do not touch the lens at high temperature.

• After soldering, any mechanical force on the lens or any excessive vibration shall not be accepted to apply, also the

circuit board shall not be bent as well.
