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. 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. The dominant wavelength d is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device. 9. Specifications are subject to change without notice. WW03A3SRP4-N2 Version 2.1 Page 2 of 4
