Procurement Notes

Verify the specific operating temperature rating against your design requirements, as some sources indicate a lower maximum temperature of 85°C or 70°C for similar variants. Confirm the package pin count and footprint compatibility with your PCB layout before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring integrated LAN signal conditioning and noise suppression. Ensure the selected variant matches the required thermal performance envelope, particularly if the system environment exceeds standard industrial limits. Verify mechanical fitment against the specified 24-pin surface mount dimensions.
