TG44-S020NXLF

Pulse Transformers Overview

The TG44-S020NXLF is a surface-mount LAN isolation transformer module from the Quatra series, designed for 10BASE-T applications. It features four isolated channels with a 40-pin SMD-40 package measuring 27.94 mm in length, 12.19 mm in width, and 5.84 mm in height. The component provides a primary-to-secondary turns ratio of 1CT:1.41 for transmitters and 1:1 for receivers. Key electrical specifications include an inductance of 140 µH, a maximum DC resistance of 400 mOhms, and an insulation voltage rating of 1.5 kV. It operates within a temperature range of 0°C to +70°C.

Pulse Transformers Feature Summary

• Provides galvanic isolation for four independent Ethernet channels
• Integrates shielded construction to minimize electromagnetic interference
• Supports standard 10BASE-T network signaling requirements

Pulse Transformers Applications

• 10BASE-T Ethernet physical layer interface circuits
• Network interface card (NIC) designs requiring signal isolation
• Industrial communication modules operating at 10 Mbps

Pulse Transformers Procurement Notes

Verify that the specific suffix 'NXLF' corresponds to the lead-free RoHS-compliant variant as documented by HALO Electronics. Confirm that the 40-pin SMD footprint matches the target PCB layout dimensions of 27.94 mm x 12.19 mm. Ensure the design accommodates the required 1.5 kV insulation clearance between primary and secondary windings for safety compliance.

Pulse Transformers Selection Notes

Select this component when a quad-channel isolation solution is required for legacy 10BASE-T networks rather than higher-speed standards. The fixed 140 µH inductance and specific 1CT:1.41/1:1 winding ratios must align with the magnetics requirements of the chosen PHY transceiver. Consider the SMD-40 package size constraints during mechanical integration.

Pulse Transformers Part Context

This part belongs to the Quatra family of LAN isolation transformers manufactured by HALO Electronics. It serves as a specialized magnetic component for Ethernet connectivity, distinct from general-purpose audio or signal transformers. The module integrates multiple transformer cores into a single shielded package to reduce board space compared to discrete solutions.

Pulse Transformers Replacement Considerations

The TG44-S020NXRL is a comparable variant within the same product line. Verify pin compatibility and identical electrical parameters before substitution.
