Frequently Asked Questions

What is an Ethernet network transformer?

Also known as an internet isolation transformer or network filter, it provides signal coupling, noise suppression, and galvanic isolation between Ethernet devices to ensure safe and reliable data transmission.

What does common mode rejection mean?

It refers to the transformer’s ability to suppress common-mode noise (interference on both signal lines) while allowing differential signals to pass, improving signal integrity in noisy environments.

What is electrical isolation in Ethernet transformers?

Electrical isolation prevents direct current flow between connected devices, protecting against ground loops, voltage spikes, and surges — critical for equipment safety and reliability.

Are Yutai’s products PoE compatible?

Yes, many of our RJ45 integrated modules support PoE (Power over Ethernet) and PoE+ (802.3af/at) standards, enabling data and power delivery over a single cable.

Can you customize transformers for specific designs?

Absolutely. We offer custom design, development, and manufacturing of magnetic components based on client specifications, including footprint, inductance, and isolation requirements.
