NOTE: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE
eye-response curve.
2.
θ
1/2
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. Iv classification code is marked on each packing bag.
5. The Iv guarantee should be added ±15% tolerance.
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.
•
When forming a lead, make sure not to apply any stress inside the resin.
•
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 recommend to use a wrist band or anti-electrostatic
glove when handling the LED. All devices, equipment and machinery must be properly grounded.
