ALMD-CM3F, ALMD-CB3F High-Brightness SMT Round Green and Blue LED Lamps Data Sheet Description Features The new Broadcom ALMD-xx3F LED series has the same or Compact form factor just slightly less luminous intensity than conventional high High brightness material brightness, through-hole LEDs. Available in green and blue colors The new LED lamps can be assembled using common SMT Green InGaN 525 nm assembly processes and are compatible with industrial reflow Blue InGaN 470 nm 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 Tinted lens Typical viewing angle: 30 For easy pick and place assembly, the LEDs are shipped in tape and reel. Every reel is shipped from a single intensity and color bin for better uniformity. Applications Mono color signs 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. CAUTION: 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 silver-plated leads to tarnish or rust, which might cause difficulties in soldering.

The luminous intensity is measured on the mechanical axis of the lamp package and it is tested with pulsing condition. c. The optical axis is closely aligned with the package mechanical axis. d. Tolerance for each bin limit is 15%. e. is the off-axis angle where the luminous intensity is half of the peak intensity. Broadcom - 2 -
