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 Everlight Electronics Co., Ltd.

The following conditions should be observed, if dry boxes are not available: ℃ to 30℃ Storage temperature 10 Storage humidity ≦60%RH max After more than 72 hours under these conditions moisture content will be too high for reflow soldering. In case of moisture absorption, the devices will recover to former condition by drying under the following condition: ℃ ℃/-0℃ and 5%RH (dry air / nitrogen), or 96 hours at 60℃+5℃ and < 5%RH for all device containers, or 24 hours at 125℃+5℃ not suitable for reel or tubes 192 hours at 40 +5 ESD Precaution: Proper storage and handing procedures should be followed to prevent ESD damage to the devices especially when they are removed from the Anti-static bag. Electro-Static Sensitive Devices warning labels are on the packing. 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. (3) After soldering, do not warp the circuit board. Everlight Electronics Co., Ltd.

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. Everlight Electronics Co., Ltd.
