Notes:
1. All dimensions are in millimeter.
2. Tolerance of measurement is ±0.25mm(.01”) unless others otherwise noted.
3. Protruded resin under flanges is 1.0mm(0.4”) max.
4. Lead spacing is measured where the leads emerge from the package.
5. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-response curve.
Tolerance of measurement of luminous intensity is ±15%
6. θ
is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
1/2
It use many parameters that correspond to the CIE 1931 2°
Tolerance of measurement of angle is ±5 degree
7. Caution in ESD: Static Electricity and surge damages the LED. lt is recommended to use a wrist band or anti-electrostatic
glove when handling the LED.All devices, equipment and machinery must be properly grounded.
8. X,Y, and Z are CIE1931 2°values of Red, Green and Blue content of the measurement.
Color Coordinates Measurement allowance is ±0.01
9. Specifications are subject to change without notice.
