Avago Introduces Tricolor Blackbody Surface Mount LEDs

Avago Technologies has introduced a family of high-brightness Blackbody tricolor surface mount (SMT) LEDs for use in indoor full color signs and displays. Available in an industry standard PLCC-4 package, the ASMT-QTC0 LED offers a wide 115-degree viewing angle, and extreme contrast and sharpness to enhance short distance viewing in a variety of indoor full color displays. Moreover, this new Blackbody LED family incorporates additional heat sinking capabilities to enable the LED to be driven at high drive currents. As a result, this Blackbody LED can operate in a wide range of environmental conditions to provide customers with high reliability. The ASMT-QTC0 package is designed to meet indoor LED screen specifications, which are often viewed at close distances and requires high brightness, high contrast and low heat dissipation to avoid the need for cooling fans in the display. For most indoor LED screens, the minimum brightness requirement is close to 600 candelas per square meter (nits). With dimensions of 3.4 mm by 3.2 mm by 2.0 mm, the ASMT-QTC0 family incorporates silicone material to extend light output performance over time. Moreover, with a moisture sensitivity level of 2a (MSL 2a) this Blackbody LED is ideal for use in SMT production environments.
