Overview
The H1270FNLT is a LAN 10G Base-T pulse transformer module manufactured by Pulse Electronics. It features surface mount technology with dimensions of 13.08mm length, 14.58mm width, and 3.68mm height. The component provides an inductance of 350µH and supports a frequency range from 100 kHz to 100 MHz. It offers 1.5 kV isolation voltage and operates within a temperature range of 0°C to +70°C. The unit includes single center tap configurations for both transmitter and receiver sides.
Feature Summary
- Designed specifically for LAN 10G Base-T applications
- Surface mount construction for automated assembly
- Provides electrical isolation between circuit ports
Applications
- 10 Gigabit Ethernet network interfaces
- LAN signal transmission modules
- High-speed data communication equipment
Procurement Notes
Verify the specific suffix 'FNL' against legacy 'NL' variants to ensure correct pin configuration and housing design. Confirm RoHS3 compliance status as required by project specifications. Check current availability as manufacturing statuses may change. Ensure the selected packaging type matches the production line requirements.
Selection Notes
Select this component when designing for 10G Base-T standards requiring integrated pulse transformers. Consider the physical footprint constraints given the 13.08mm x 14.58mm package size. Evaluate thermal performance within the specified 0°C to +70°C operating range. Verify compatibility with existing board layouts if replacing older NL series parts.
Part Context
This part belongs to Pulse Electronics' LAN transformer portfolio. It serves as a modern replacement for discontinued models like the H1270NLT. The FNL designation indicates a specific thermoplastic case design with inserted pins, differing from earlier molded pin constructions. This evolution ensures compliance with updated regulatory injunctions while maintaining functional equivalence.
Replacement Considerations
The H1270FNLT is the direct successor to the obsolete H1270NLT. Verify that the new housing dimensions are compatible with existing footprints before substitution.
