Procurement Notes
Verify the specific suffix '2SMT&R' against the manufacturer's current datasheet to confirm reel quantity and tape specifications. Ensure the component matches the required lead-free status and RoHS compliance if mandated by your project standards. Cross-reference the date code and lot number upon receipt to maintain supply chain traceability and quality assurance protocols.
Selection Notes
Select this component when surface-mount assembly is required for optocoupler functions. Consider the forward voltage drop of the LED and the collector-emitter saturation voltage of the phototransistor for circuit design compatibility. Verify that the isolation voltage rating meets the safety requirements of the application environment and regulatory standards.
Part Context
This part belongs to Isocom Components' family of surface-mount optocouplers. These devices are engineered to replace through-hole equivalents in space-constrained designs. The series offers standardized pinouts and electrical characteristics suitable for various industrial and consumer electronics applications requiring reliable optical isolation.
