IPC/JEDEC Moisture Sensitivity Level Table 4 - IPC/JEDEC J-STD-20D.1 MSL Classification:
Soak Requirements Floor Life Standard Accelerated Level
Time Conditions Time (hrs) Conditions Time (hrs) Conditions ≤ 30°C/ 168 85°C/ 1 Unlimited n/a n/a 85% RH +5/-0 85% RH Notes for Table 4: 1. The standard soak time includes a default value of 24 hours for semiconductor manufacturer’s exposure time (MET) between bake and bag and includes the maximum time allowed out of the bag at the distributor’s facility. Average Lumen Maintenance Projections Lumen maintenance generally describes the ability of a lamp to retain its output over time. The useful lifetime for solid state lighting devices (Power LEDs) is also defined as Lumen Maintenance, with the percentage of the original light output remaining at a defined time period. Based on long-term WHTOL testing, LedEngin projects that the LZ Series will deliver, on average, 90% Lumen Maintenance at 100,000 hours of operation at a forward current of 1000 mA. This projection is based on constant current operation with junction temperature maintained at or below 125°C.
