Procurement Notes
Verify the specific suffix codes against the manufacturer datasheet to confirm pinout orientation and lead configuration. Ensure compliance with RoHS directives if required by the target application. Confirm availability status as distribution channels may vary. Cross-reference part numbers carefully to avoid confusion with through-hole or alternative variant versions.
Selection Notes
Select this component when surface-mount technology is required for space-constrained designs. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the CTR specifications relative to the driving circuit requirements. Verify thermal management needs given the operating temperature range and power dissipation limits.
