ALMD-LM38, ALMD-LB38 High Brightness SMT Oval Green and Blue LED Lamps Data Sheet Description Features The Broadcom ALMD-Lx38 Oval LED series has the same or Well defined spatial radiation pattern just slightly less luminous intensity than conventional high High brightness material brightness through holes LEDs. Available in Green and Blue LED The new Oval LED lamps can be assembled using common Green InGaN 525 nm SMT assembly processes and are compatible with industrial Blue InGaN 470 nm reflow soldering processes. JEDEC MSL 2A The LEDs are made with an advanced optical grade epoxy for Compatible with the reflow soldering process superior performance in outdoor sign applications. The surface Tinted and diffused lens mount Oval LEDs are specifically designed for full color/video Wide viewing angle: 40 100 signs and indoor or outdoor passenger information sign applications. Applications For easy pick and place assembly, the LEDs are shipped in tape and reel. Every reeled is shipped from a single intensity and Mono color signs color bin for better uniformity. CAUTION InGaN devices are Class 1C HBM ESD sensitive, AlInGaP devices are Class 1B ESD sensitive per JEDEC Standard. Please observe appropriate precautions during handling and processing. Refer to Application Note AN-1142 for additional details. Customers should always keep the LED in the moisture barrier bag (MBB) with <5% RH when not in use because prolonged exposure to the environment might cause the leads to tarnish or rust, which might cause difficulties in soldering.
