• Supports 2.5 Gigabit data transmission rates
• Provides 1.5 kV electrical isolation between channels
• Rated for extended industrial temperature environments up to 125°C

Applications

• 2.5G Ethernet controller interfaces
• Industrial networking equipment
• Automotive infotainment systems
• High-speed data communication modules

Procurement Notes

Verify the specific datasheet revision and pinout configuration before integration, as manufacturer specifications may update. Confirm that the gull-wing footprint matches the target PCB design constraints. Ensure thermal management strategies account for the maximum operating temperature of 125°C in enclosed assemblies. Cross-reference with official Pulse Electronics documentation for accurate mechanical dimensions and soldering profiles.

Selection Notes

Select this component when designing circuits requiring 2.5G Ethernet connectivity with high isolation requirements. The wide temperature range makes it suitable for harsh environments where standard commercial grade parts would fail. Consider the surface-mount form factor for automated assembly processes. Verify compatibility with the specific PHY controller's impedance matching needs.

Part Context

This part belongs to Pulse Electronics' portfolio of Ethernet magnetics solutions. It serves as a critical interface component between the physical layer transceiver and the network medium. The dual-channel design simplifies board layout by integrating multiple functions into a single package, reducing component count and potential failure points in high-density designs.

Replacement Considerations

Consult official distributor databases for verified cross-references. Ensure any substitute maintains the 2.5G speed rating and 1.5 kV isolation specification. Mechanical footprint compatibility must be confirmed prior to substitution.
