Procurement Notes

Verify the specific datasheet version and isolation voltage rating (4 kV vs 1.5 kV) against official manufacturer documentation, as conflicting data exists across distributor listings. Confirm the exact package type and lead frame material requirements for your assembly process. Ensure compatibility with the specified peak reflow temperature of +245°C during soldering operations. Cross-reference the part number suffix 'NLT' to confirm tape and reel packaging specifications.

Selection Notes

Select this component when a 350 µH inductance and 4 kV isolation are required for surface-mount LAN or signal applications. Consider the 1 kHz to 100 MHz frequency range for suitability in high-speed data transmission environments. Evaluate the -40°C to +85°C operating temperature range against environmental constraints. Verify that the unshielded design meets electromagnetic interference requirements for the target board layout.
