H5084FNLT

Overview

The H5084FNLT is a surface-mount LAN transformer module from Pulse Electronics, designed for 10/100/1000 Base-T applications. It features a quad channel configuration with a 350 µH inductance and a 1CT:1CT turns ratio for both transmitter and receiver sides. The component operates within a temperature range of 0°C to 70°C and measures 15.24 mm x 9.78 mm x 4.14 mm. It supports SMD/SMT termination and is available in reel, cut tape, or Digi-Reel packaging formats.

Feature Summary

• Integrated magnetic module supporting 10/100/1000 Base-T Ethernet standards
• Surface mount construction for automated assembly processes
• Quad channel design with specified 350 µH inductance
• RoHS compliant manufacturing without lead content

Applications

• 1000 Base-T network interface circuits
• 100 Base-T Ethernet connectivity modules
• 10 Base-T legacy network interfaces
• LAN port isolation and signal conditioning

Procurement Notes

Verify the specific suffix 'FNLT' to confirm surface mount reel packaging and RoHS compliance status. Ensure the selected variant matches the required 15.24mm x 9.78mm footprint dimensions for PCB layout compatibility. Confirm operating temperature range requirements align with the 0°C to 70°C specification before finalizing procurement orders.

Selection Notes

Select this component when a single-port, non-PoE solution is required for Gigabit Ethernet designs. The 1CT:1CT ratio suits standard differential line driver configurations. Consider the physical height constraint of 4.14mm for low-profile board assemblies. Verify that the 350 µH inductance meets the common mode rejection requirements of the target network topology.

Part Context

This part belongs to the H5084 series of LAN transformers manufactured by Pulse Electronics. It serves as a critical isolation component between the Ethernet PHY and the RJ45 connector. The series provides integrated magnetics to reduce board space and simplify EMI filtering requirements in modern networking equipment designs.

Replacement Considerations

H5084FNL is a parameter-equivalent alternative available in tube packaging instead of tape and reel format.
