Overview
The EX2024FNLT is a surface-mount LAN pulse transformer module manufactured by Pulse Electronics, designed for 10Base-T applications. It features an inductance of 35µH and 200µH with a turns ratio of 1CT:2.5CT for the transmitter and 1CT:1CT for the receiver. The component measures 12.65mm x 8.89mm with a maximum height of 5.08mm. It operates within a temperature range of -40°C to 85°C and is supplied in tape and reel packaging.
Feature Summary
- Integrated isolation and data interface module for Ethernet signaling
- Optimized for non-PoE 10Base-T transmission and reception paths
- Surface-mount construction for automated assembly processes
Applications
- 10Base-T Ethernet network interfaces
- LAN port signal conditioning circuits
- Network interface card (NIC) designs
Procurement Notes
Verify that the specific suffix FNLT corresponds to the required tape-and-reel packaging format rather than tube packaging. Confirm the operational temperature range meets the target environment requirements, as this variant supports extended industrial temperatures compared to standard commercial options. Ensure compatibility with non-PoE circuit topologies.
Selection Notes
Select this component when designing for 10Base-T standards requiring integrated magnetics. Compare against the EX2024NLT if higher inductance values or different thermal ratings are necessary. Consider physical footprint constraints given the 12.65mm length. Verify that the 1CT:2.5CT primary configuration aligns with the upstream driver circuit design specifications.
Part Context
This part belongs to the EX2024 series of LAN transformers from Pulse Electronics. It serves as a specialized solution for Ethernet connectivity, distinct from general-purpose audio or signal transformers. The series includes variants with different packaging and electrical characteristics to support diverse board layout and performance needs.
Replacement Considerations
The EX2024NL is listed as a parameter-equivalent alternative. Verify if the tube packaging of the NL variant fits the production workflow. Check if the 350µH inductance of the NL variant is acceptable for the specific 10Base-T application requirements.
