Fairchild Semiconductor QCK4
The QCK3/QCK4 is a slotted opticalswitch designed for surface mount applications where extreme temperatures are experienced during solder reflow. The switch consists of a GaAs LED and a silicon photodarlington facing each other across a.157" (4.0 mm) gap. The leads are formed to sit flush on a PCB during solder reflow.| Part No. | QCK4 |
