Frequently Asked Questions (FAQ) 

Q: What PoE standards does the TG24010S1H2 Gigabit LAN Transformer support?

A: The TG24010S1H2 supports IEEE 802.3at (PoE+) with a continuous current rating of 720mA, enabling power delivery up to 25.5W per port. It is backward compatible with IEEE 802.3af (PoE) applications at lower current levels and is compatible with Type 2 PD designs. For IEEE 802.3bt (PoE++) high-power applications requiring 60W or more, please consult VITALCONN for alternative transformer recommendations.

Q: Can this 10/100/1000M Gigabit LAN Transformer SMT module be wave soldered?

A: The TG24010S1H2 is designed specifically for reflow soldering with a peak temperature of ≤250°C for 10 seconds and a maximum of 3 reflow cycles. Wave soldering is not recommended as the open-header SMT package may not reliably withstand the solder wave process. Please follow the recommended reflow profile provided in the product datasheet.

Q: What is the recommended PCB land pattern and clearance for the 1500V isolation rating?

A: The PCB land pattern and recommended creepage/clearance distances to maintain the 1500 VAC isolation rating are detailed in the TG24010S1H2 product drawing. As a general guideline, a minimum creepage distance of 4.0mm between primary and secondary side traces is recommended for reinforced isolation at this voltage level. Always design PCB layout to comply with applicable safety standards (IEC 60950-1, IEC 62368-1) for your target market.
