GU4929RM LF

Overview

The GU4929RM LF is a LAN 1000 Base-T pulse transformer manufactured by Pulse Electronics. It supports 1G DIP 4 PORT POE with 90W power capability. The component features an inductance of 350µH and utilizes a 1:1CT transmitter and 1:1CT receiver configuration. Designed for through-hole mounting, it measures 33.50mm x 29.00mm with a maximum seated height of 16.80mm.

Feature Summary

• Supports 1000 Base-T LAN transmission standards
• Enables Power over Ethernet (POE) functionality up to 90W
• Integrated 1:1CT transmitter and receiver topology

Applications

• 1 Gigabit Ethernet network interfaces
• Power over Ethernet powered devices
• LAN port signal conditioning circuits

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the through-hole package dimensions align with your PCB footprint requirements. Ensure the 90W POE rating meets the power budget of your target application design.

Selection Notes

Select this component when a 1000 Base-T solution with integrated high-power POE support is required. The through-hole format suits applications where mechanical robustness is prioritized over surface area constraints. Verify compatibility with standard LAN transformer pinouts for seamless integration into existing network interface designs.

Part Context

This part belongs to Pulse Electronics' MDL series of LAN transformers. It is designed for high-speed data transmission while simultaneously delivering electrical power over the same cabling infrastructure. The unit integrates multiple windings to handle both data signals and power delivery within a single compact magnetic assembly.

Replacement Considerations

The GU4629RM LF is a documented alternative offering similar specifications but rated for 60W POE instead of 90W. Verify if the reduced power capacity meets your application requirements before substituting.
