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 Everlight Electronics Co., Ltd.

(2) When soldering, do not put stress on the devices during heating. (3) After soldering, do not warp the circuit board. Soldering Iron ℃ Each terminal is to go to the tip of soldering iron temperature less than 350 for 3 seconds within once in less than the soldering iron capacity 25W. 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.
