Frequently Asked Questions (FAQ) 

  • Q: What is the difference between TG24052S1 and TG24042S1 LAN Transformer Modules?
  • A: The primary difference is the application speed: TG24052S1 is specifically designed for 2.5G Base-T (NBASE-T) with 180 uH OCL, while TG24042S1 targets 1000Base-T Gigabit Ethernet with 350 uH OCL. Both share the same 24-pin SMT open header package and 1500 Vrms HIPOT rating.
  • Q: Does the TG24042S1 support Power over Ethernet (PoE)?
  • A: While the TG24042S1 provides 1500 Vrms isolation suitable for PoE applications, we recommend confirming the specific PoE current rating with our engineering team, as different variants within the TG24 series may have varying PoE capabilities. Contact info@vitalconn.com for detailed PoE specifications.
  • Q: Where can I find the PCB footprint and mechanical dimensions for this Gigabit LAN Transformer?
  • A: Complete mechanical drawings including recommended PCB land patterns, pin assignments, and dimensional tolerances are included in the TG24042S1 product datasheet. The datasheet is available from the VITALCONN website or by request from our technical support team.
