TG42-4406NCRL

Pulse Transformers Overview

The TG42-4406NCRL is a LAN isolation transformer module designed for 10BASE-T applications. It features a single-channel configuration with SMD/SMT termination in an SMD-12 package measuring 17.15 mm x 11.56 mm x 8.64 mm. The component provides 4.5 kV insulation voltage and operates within a temperature range of 0°C to +70°C. Key electrical specifications include a typical inductance of 140 µH and turn ratios of 1:1 for the transmitter and 1:1.41 for the receiver.

Pulse Transformers Feature Summary

• Provides reinforced electrical isolation for network interface circuits
• Supports standard 10BASE-T Ethernet signaling protocols
• Utilizes surface-mount technology for automated assembly integration

Pulse Transformers Applications

• 10BASE-T network interface modules
• Ethernet physical layer (PHY) isolation stages
• Industrial communication equipment requiring reinforced isolation

Pulse Transformers Procurement Notes

Verify that the specific NCRL suffix corresponds to the required lead-free and halogen-free compliance status, as manufacturing revisions may alter material composition. Confirm that the SMD-12 footprint matches the target PCB layout dimensions precisely. Ensure the 4.5 kV insulation rating meets the safety standards applicable to the final end-product environment. Cross-reference the manufacturer datasheet for any recent product change notices affecting pinout or mechanical tolerances.

Pulse Transformers Selection Notes

Select this component when a single-port solution with high isolation voltage is required for legacy 10BASE-T designs. The 140 µH inductance value supports standard impedance matching requirements for this protocol. Consider the SMD-12 package size constraints against available board space. Evaluate the operating temperature range limits against the intended deployment environment thermal profile.

Pulse Transformers Part Context

This part belongs to the TG-10BT series of LAN isolation transformers manufactured by HALO Electronics. The series focuses on providing reliable signal coupling and galvanic isolation for Ethernet interfaces. The TG42 variant specifically addresses single-port requirements, distinguishing it from multi-port solutions like the TG44 series which support quad configurations.
