Note: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE
(Commission International De L'Eclairage) eye-response 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 represents the single
wavelength which defines the color of the device.
4. The Iv guarantee should be added ±15%.

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
The storage ambient for the LEDs should not exceed 30°C temperature or 70% relative humidity.
It is recommended that LEDs out of their original packaging are used within three months.
For extended storage out of their original packaging, it is recommended that the LEDs be stored in
a sealed container with appropriate desiccant or in desiccators with nitrogen ambient.
3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LEDs if necessary.
4. Lead Forming & Assembly
During lead forming, the leads should be bent at a point at least 3mm from the base of LED lens.
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
When soldering, leave a minimum of 2mm clearance from the base of the lens to the soldering point.
Dipping the lens into the solder must be avoided.
Do not apply any external stress to the lead frame during soldering while the LED is at high temperature.

6. 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

(B) The brightness of each LED might appear different due to the differences in the I-V characteristics
of those LEDs
