The Broadcom ASMT-QWBx series 0.5W Cool White Power PLCC4 SMT LED lamps use InGaN chip technology and superior package design to enable them to produce higher light output with better flux performance. They can be driven at high current and are able to dissipate the heat more efficiently resulting in better performance with higher reliability.

These lamps are able to operate under a wide range of environmental conditions making them ideal for various applications including fluorescent replacement, under cabinet lighting, retail display lighting and panel lights.

To facilitate easy pick and place assembly, the LEDs are packed in EIA-compliant tape and reel. Every reel is shipped in single intensity and color bin, to provide close uniformity.
