Notes :
(1) Tolerance : VF :±0.1V, IV :±7%, x,y :±0.005
(2) The luminous intensity IV was measured at the peak of the spatial pattern which may not be
aligned with the mechanical axis of the LED package.
(3) Correlated Color is derived from the CIE 1931 Chromaticity diagram.
(4) Θ_1/2 is the off-axis where the luminous intensity is 1/2 of the peak intensity
(5) Thermal resistance = Rth JA : Junction/ambient , Rth JS : Junction/solder point
Pad design for improved heat dissipation : Cu-area > Cu 16mm2 per pad, FR4, t=1.6mm
(6) Not designed for reverse operation
