Notes:

Luminous intensity is measured with a light sensor and filtercombination that approximates the CIE eye-response curve.2θ1/2

is the o-axis angle where the luminous intensity is 1⁄2the peak intensity.c.   The dominant wavelength (λd) is derived from

the CIEchromaticity diagram and represents the single wavelength which defines thecolor of the device.

Through-hole Rectangular LEDs aresuitable for all applications requiring instruments, switches, iconbacklighting, and general status

indication. There are 3 types oftechnology based LEDs lamps. The chips with GaP technology are for low tomoderate light output requirements,

and the ones with AllnGaP and InGaNtechnologies are for high brightness light output.

Through-hole Rectangular LEDs areoffered in a variety of packages such as 1.0*5.0mm, 2*3mm, 1.9*3.9mm, 2*5mm,3*3mm, 3.7*6.3mm, 5*5mm,

with integrated built-in resistor or low currentoptions, and color choices include green, red, yellow, white, blue and orange.

These devices are molded from advancedoptical grade epoxy, which provide superior high temperature performance andexcellent moisture

resistance. Diffused, color transparent and optical designare balanced to yield superior light output. Several intensity choices areavailable

in each color for increasing design flexibility.
