Procurement Notes

Verify the specific datasheet version and revision history before procurement, as component specifications may evolve. Confirm that the surface mount footprint matches the target board layout exactly. Ensure the operating temperature range aligns with the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when designing for 100 Base-TX standards requiring a compact dual-channel solution. The 350 µH inductance value is critical for matching impedance requirements in the intended network application. Consider the SMD package size constraints during the PCB layout phase. Verify compatibility with the soldering profile specified in the official documentation to ensure reliable joint formation.
