Notes:
1. Luminous flux is measured with a light sensor and filter combination that approximates the CIE eye-response curve.
2. Lm classification code is marked on each packing bag.
3. The chromaticity coordinates (x, y) is derived from the 1931 CIE chromaticity diagram.
4. Caution in ESD:
Static Electricity and surge damages the LED. It is recommend to use a wrist band or anti-Electrostatic glove when
handling the LED. All devices, equipment and machinery must be properly grounded.
5. CAS140B is the test standard for the chromaticity coordinates (x, y) & lm.
6. The chromaticity coordinates (x, y) guarantee should be added +/- 0.01 tolerance.
7. The Forward Voltage (Vf) guarantee should be added ± 0.10 volt tolerance.

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 Liteon’s Sales in advance for information 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 equipment, medical and life support systems and safety devices).
2. Storage
This product is qualified as Moisture sensitive Level 3 per JEDEC J-STD-020 Precaution when handing this moisture sensitive
product is important to ensure the reliability of the product.
The package is sealed:
The LEDs should be stored at 30°C or less and 90%RH or less. And the LEDs are limited to use within one year, while the
LEDs is packed in moisture-proof package with the desiccants inside.
The package is opened:
The LEDs should be stored at 30°C or less and 60%RH or less. Moreover, the LEDs are limited to solder process within
168hrs. If the Humidity Indicator shows the pink color in 10% even higher or exceed the storage limiting time since opened,
that we recommended to baking LEDs at 60°C at least 48hrs. To seal the remainder LEDs return to package, it’s
recommended to be with workable desiccants in original package.
3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary.

5. Drive Method
An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs connected in parallel in an
application, it is recommended that a current limiting resistor be incorporated in the drive circuit, in series with each LED as
shown in Circuit A below.
Circuit model A
Circuit model B
LED
LED
(A) Recommended circuit.
(B) The brightness of each LED might appear different due to the differences in the I-V characteristics
of those LEDs.
6. ESD (Electrostatic Discharge)
Static Electricity or power surge will damage the LED.
Suggestions to prevent ESD damage:
Use of a conductive wrist band or anti-Electrostatic glove when handling these LEDs.
All devices, equipment, and machinery must be properly grounded.
Work tables, storage racks, etc. should be properly grounded.
Use ion blower to neutralize the static charge which might have built up on surface of the LED’s plastic lens as a result of
friction between LEDs during storage and handling.
ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low forward voltage, or “ no
lightup ” at low currents.
To verify for ESD damage, check for “ lightup ” and Vf of the suspect LEDs at low currents.
The Vf of “ good ” LEDs should be >2.0V@0.1mA for InGaN product
