Procurement Notes
Verify the specific suffix 'SMT&R' confirms surface mount tape and reel packaging requirements. Ensure the 'X' designation aligns with the manufacturer's specific binning or testing criteria. Confirm that the dual-channel variant matches the intended PCB footprint and isolation clearance needs. Cross-reference the 5.3kVrms rating against system safety standards. Validate operating temperature range suitability for the target environment.
Selection Notes
Select this component when dual-channel isolation with AC input capability is required. The surface mount package offers space efficiency compared to through-hole alternatives. Consider the 5.3kVrms isolation voltage for applications involving significant potential differences. The inverse parallel LED structure eliminates the need for external rectification circuits. Evaluate the 4µs rise time against signal frequency requirements.
