Part No. : LTSA-T680UBWT

BNS-OD-FC002/A4

SMD LED

LTSA-T680UBWT

Notes:

1.

Luminous intensity is measured with a light sensor and filter combination that approximates the CIE

eye-response curve

2.

θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.

3.

The domi

nant wavelength, λd is derived from the CIE chromaticity diagram and represents the single

wavelength which defines the color of the device.

4.

Forward Voltage Tolerance is +/- 0.1 volt.

5.

Reverse voltage (VR) condition is applied to IR test only. The device is not designed for reverse operation.
