Procurement Notes
Verify the specific suffix (e.g., X001) against official Vishay documentation to confirm packaging type and tape/reel specifications. Ensure the requested variant matches the required DIP-4 through-hole configuration. Cross-reference the manufacturer part number with authorized distributors to confirm active status and availability. Check RoHS compliance details in the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and moderate speed are required for digital signal transmission. Consider the 40-125% CTR range for circuit design margins. Evaluate the 3 µs switching time against system frequency requirements. Compare power dissipation limits with thermal management capabilities in the target application environment.
