ASMT-Bx20
PCB Based Subminiature Lamps (PCB PolyLED)
Data Sheet
Description
The ASMT-Bx20 is an environmental friendly green
product of unique PCB based subminiature lamps,
namely PCB PolyLED. These PolyLEDs come in un-tinted,
non-diffused package to cater for various product themes
and ease handling applications.
The small size, narrow footprint, and high brightness
make these LEDs excellent for backlighting, status indica-
tion, and panel illumination applications.
The available colors are AllnGaP Red, AllnGaP Green,
InGaN Blue, and AllnGaP Amber.
In order to facilitate pick and place operation, these PCB
PolyLEDs are shipped in tape and reel, with 1500 units
per reel. The package is compatible with reflow soldering
and binned by both color and intensity.

Notes:
1. The luminous intensity IV is measured at the peak of the spatial radiation pattern which may not be aligned with the mechanical axis of the LED
package.
2. The dominant wavelength,
λ
d
, is derived from the CIE Chromaticity Diagram and represents the perceived color of the device.
3.
θ
1/2
is the off-axis angle where the luminous intensity is ½ the peak intensity.
