ALMD-CY3F-YZ002 Data Sheet High Brightness SMT Round White LED Lamps Broadcom ALMD-CY3F-DS100 Handling of Moisture-Sensitive Devices This product has a Moisture Sensitive Level 3 rating per JEDEC J-STD-020. Refer to Broadcom Application Note AN5305, Handling of Moisture Sensitive Surface Mount Devices for additional details and a review of proper handling procedures.  Before use: – An unopened moisture barrier bag (MBB) can be stored at < 40°C/90% RH for 12 months. If the actual shelf life has exceeded 12 months and the humidity indicator card (HIC) indicates that baking is not required, it is safe to reflow the LEDs per the original MSL rating. – Do not open the MBB pr ior to assembly (for example, for IQC). If unavoidable, the MBB must be properly resealed with fresh desiccant and HIC. The exposed duration must be taken in as floor life.  Control after opening the MBB: – Read the HIC immediat ely upon opening of MBB. – Keep the LEDs at < 30°C/60 % RH at all times, and complete all high temperature-related processes, i ncluding soldering, curing, or rework within 168 hours.  Control for unfinished reel: Store unused LEDs in a sealed MBB with desiccant or a desiccator at < 5% RH.  Control of assembled boards: If the PCB soldered with the LEDs is to be subjected to other high-temperature processes, store the PCB in a sealed MBB with desiccant or desiccator at < 5% RH to ensure that all LEDs have not exceeded their floor life of 168 hours.  Baking is required if: – The HIC indicator indicates a change in color for 10% and 5%, as stated on the HIC. – The LEDs are exposed to conditions of > 30°C/60% RH at any time. – The LED's floor life exceeded 168 hours. The recommended baking condition is: 60°C ± 5ºC for 20 hours. Baking can only be done once.  Storage: The soldering terminals of these Broadcom LEDs are silver plated. If the LEDs are exposed in ambient environments for too long, the silver plating might be oxidized, thus affecting its solderability performance. As such, keep unused LEDs in a sealed MBB with desiccant or in a desiccator at < 5% RH. Application Precautions  The drive current of the LED must not exceed the maximum allowable limit across temperature as stated in the data sheet. Constant current driving is recommended to ensure consistent performance.  Circuit design must cater to the whole range of forward voltage (VF) of the LEDs to ensure the intended drive current can always be achieved.  The LED exhibits slightly different characteristics at different drive currents, which may result in a larger variation of performance (meaning: intensity, wavelength, and forward voltage). Set the application current as close as possible to the test current to minimize these variations.  The LED is not intended for reverse bias. Use other appropriate components for such purposes. When driving the LED in matrix form, ensure that the reverse bias voltage does not exceed the allowable limit of the LED.  White LEDs must not be exposed to acidic environments and must not be used in the vicinity of any compound that may have acidic outgas, such as, but not limited to, acrylate adhesive. These environments have an adverse effect on LED performance.  As actual application might not be exactly similar to the test conditions, do verify that the LED will not be damaged by prolonged exposure in the intended environment.  Avoid rapid changes in ambient temperature, especially in high-humidity environments, because they cause condensation on the LED.  If the LED is intended to be used in harsh or outdoor environments, protect the LED against damages caused by rain water, water, dust, oil, corrosive gases, external mechanical stresses, and so on.
