The component supports an ET rating of 250 V/us and provides an isolation voltage of 4000 Vrms. Operating temperatures range from -40°C to +125°C. Physical dimensions are 16.70 mm in length, 12.70 mm in width, and 14.20 mm in height.

Feature Summary

• High isolation capability with reinforced insulation design
• Surface mount technology for automated assembly
• Wide operating temperature range for harsh environments

Applications

• Power over Ethernet (PoE) interfaces
• Industrial communication networks
• Medical equipment signal isolation

Procurement Notes

Verify the specific isolation voltage requirement against datasheet specifications, as sources indicate variations between 4000 Vrms and 5000 Vrms. Confirm package dimensions match PCB footprint requirements. Check RoHS compliance status for regulatory adherence. Ensure thermal management aligns with the maximum operating temperature limit during integration.

Selection Notes

Select this component when high voltage isolation is critical for safety or noise immunity. The 1:2:2 turns ratio suits specific impedance matching needs in differential signaling. Consider the physical size constraints due to the 14.20 mm height. Evaluate thermal performance within the specified temperature range for reliable operation in enclosed spaces.

Part Context

This part belongs to the PH9400 series of high isolation SMT transformers. It complements other variants like PH9400.111ANLT which may offer different isolation ratings. The series targets applications requiring robust electrical separation between circuit sections while maintaining signal integrity in compact form factors.

Replacement Considerations

PH9400NLKIT is listed as a related kit but serves as a test solution rather than a direct substitute. Verify pinout compatibility and electrical parameters before substituting with other high-isolation transformers from the same manufacturer.
