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-diused 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 reow soldering

and binned by both color and intensity.

Features

• Small foot print

• Available in four colors

• Low power consumption

• Non-diused 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 reow

soldering process

Applications

• Panel indicator

• LCD backlighting

• Symbol backlighting

• Push-button backlighting

• Indoor mono/full color sign

Package Dimensions

Notes:

1. All dimensions in millimeters.

2. Tolerance is ±0.1mm unless otherwise specied.
