Frequently Asked Questions (FAQ) 

  • Q: What is the OCL specification for the TG24107S1 LAN Transformer Modules and why does it matter?
  • A: The TG24107S1 has a minimum open-circuit inductance (OCL) of 350 uH measured at 100 kHz with 100 mV and 8 mA DC bias. This inductance value is critical for 1000Base-T operation because it determines the transformer's ability to maintain signal integrity at low frequencies. Insufficient OCL can cause baseline wander and increased bit error rates in Gigabit Ethernet links.
  • Q: Can the TG24107S1 single port LAN Transformer Modules be used in PoE (Power over Ethernet) applications?
  • A: The TG24107S1 is designed for 1000Base-T data-only applications with 1500 VAC isolation rating. For PoE applications that require current-carrying capability through the transformer windings (up to 350-600 mA per pair), VITALCONN offers dedicated PoE-compatible transformer modules. Please consult the product datasheet or contact our technical team for PoE-specific magnetic module recommendations.
  • Q: What PCB land pattern and reflow profile should be used for the TG24107S1 24-pin SMT package?
  • A: The TG24107S1 uses a standard 24-pin SMT footprint compatible with industry-standard 1000Base-T magnetics layouts. The package supports lead-free reflow soldering with a peak temperature of 260 °C per JEDEC J-STD-020. For detailed land pattern dimensions and recommended reflow profiles, please refer to the TG24107S1 product datasheet or contact VITALCONN application engineering support.
