TG46-S020NXLF

Pulse Transformers Overview

The TG46-S020NXLF is a LAN isolation transformer module designed for 10BASE-T applications. It features a surface mount (SMD) package with 40 pins and operates within a temperature range of 0°C to +70°C. The component provides electrical isolation with a voltage rating of 1.5 kV. Key electrical parameters include an inductance of 140 µH, a primary coil resistance of 400 mOhms, and a maximum DC resistance of 400 mOhms. The turns ratio is specified as 1CT:1.41CT for the transmitter and 1:1 for the receiver. The module is shielded and belongs to the Quatra series.

Pulse Transformers Feature Summary

• Provides galvanic isolation for 10BASE-T Ethernet signal transmission
• Integrates transmitter and receiver functions in a single quad-port module
• Features shielded construction to minimize electromagnetic interference

Pulse Transformers Applications

• 10BASE-T network interface cards
• Ethernet hub and switch ports
• Industrial communication modules requiring 10 Mbps connectivity

Pulse Transformers Procurement Notes

Verify the specific ordering suffix to confirm packaging type; the LF suffix indicates lead-free compliance. Confirm that the required quantity aligns with the factory tube packaging quantity of 18 units per tube. Ensure the design accommodates the SMD-40 footprint dimensions of 27.94 mm length, 12.19 mm width, and 5.84 mm height. Check for any recent production cycle updates or lead time changes directly from HALO Electronics before finalizing procurement plans.

Pulse Transformers Selection Notes

Select this component when designing systems strictly adhering to the 10BASE-T standard. The 140 µH inductance value is critical for matching the impedance requirements of the physical layer transceiver. Consider the 1.5 kV isolation voltage if environmental noise levels are high. The operating temperature range of 0°C to +70°C suits standard commercial environments but may require alternative solutions for extended industrial ranges.

Pulse Transformers Part Context

This part belongs to the Quatra series of LAN isolation transformers manufactured by HALO Electronics. It is specifically engineered for 10BASE-T applications, distinguishing it from Gigabit Ethernet variants like the TG1G series. The module integrates multiple windings into a compact SMD form factor, replacing discrete transformer components to save board space and simplify assembly processes in legacy networking hardware.

Pulse Transformers Replacement Considerations

The TG46-S020NXRL serves as a reel-based variant of the same functional component. Verify pin compatibility and mechanical dimensions when substituting between tube and reel packaging formats. No other cross-model replacements are confirmed in public documentation.
