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-diused 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 reow soldering
and binned by both color and intensity.
Features
• Small foot print
• Available in four colors
• Low power consumption
• Non-diused dome for high brightness
• Supreme product quality and reliability
• Operating temperature range of -40 °C to +85°C
• Package in 8mm tape on 7” diameter reels
• Compatible with automated placement equipment
• Compatible with infrared and vapor phase reow
soldering process
Applications
• Panel indicator
• LCD backlighting
• Symbol backlighting
• Push-button backlighting
• Indoor mono/full color sign

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, λd, is derived from the CIE Chromaticity Diagram and represents the perceived color of the device.
3. θ1/2 is the o-axis angle where the luminous intensity is ½ the peak intensity.
