The output voltage (Vout) is the product of photocurrent (IPH) and loading resistor (RL) 2. A right loading resistor shall be chosen to meet the requirement of maximum ambient light, and output saturation voltage: Vout(max.) = Iout(max.) × RL ≦ Vout(saturation)＝Vcc－0.8V 3. To avoid 60Hz ripple from fluorescent lamps, we suggest that the time constant must be greater than 0.5 second: RL × CL ≧ 0.5 7 (empirical data) Copyright © 2010, Everlight Americas Inc.

Do not open moisture proof bag before devices are ready to use. 2. Shelf life in sealed bag from the bag seal date: 18 months at 10°C~30°C and < 90% RH. 3. After opening the package, the devices must be stored at 10°C~30°C and life).  60%RH, and used within 1 year (floor 4. If the moisture absorbent material (desiccant material) has faded or unopened bag has exceeded the shelf life or devices (out of bag) have exceeded the floor life, baking treatment is required. 5. If baking is required, refer to IPC/JEDEC J-STD-033 for bake procedure or recommend the following conditions: 192 hours at 40°C +5/–0°C and < 5 % RH (reeled/tubed/loose units) or 96 hours at 60°C ± 5°C and < 5 % RH (reeled/tubed/loose units) or 24 hours at 125°C ± 5°C, not suitable for reel or tubes. Recommended Solder Profile Notice: (1) Reflow soldering should not be done more than two times. (2) When soldering, do not put stress on the devices during heating.

Leave two seconds and more intervals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder. Repairing Repair should not be done after the device have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the characteristics of the device will or will not be damaged by repairing. 9 Copyright © 2010, Everlight Americas Inc. All Rights Reserved.
