NOTE:
1. Luminous intensity is measured with a light sensor and filter combination that approximates the
CIE eye-response curve.
2. The Iv guarantee should be added

tolerance.
3. Iv classification code is marked on each packing bag.
4.
θ
1/2
is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
5. The chromaticity coordinates (x, y) is derived from the 1931 CIE chromaticity diagram.
6. Precautions in handling:
•
When soldering, leave 2mm of minimum clearance from the resin to the soldering point.
•
Dipping the resin to solder must be avoided.
•
Correcting the soldered position after soldering must be avoided.
•
In soldering, do not apply any stress to the lead frame particularly when heated.
•
Lead forming must be done before soldering.
•
It is necessary to cut the lead frame at normal temperature.
7. Caution in ESD:
Static Electricity and surge damages the LED. It is recommended using a wrist band or
anti-electrostatic glove when handling the LED. All devices, equipment and machinery must be
properly grounded.
