EL3H7-G
An optical link inside the EL3H7-G allows a signal to cross between electrically isolated circuit sections. As a transistor-output optocoupler, it is useful in isolated sensing, control interfaces, and feedback paths. The supplied implementation is surface mount, using a four-pin symbol paired with the four-pad OPTO-SMD-4_L4.4-W2.7-P1.27-LS7.0-TL footprint. Its free KiCad file set also includes a 3D model so the package can be viewed in the board assembly. Conversion and editor checks were performed on files originating from a real ProtoFlow import. Open this part directly in ProtoFlow when building the corresponding schematic and PCB.
