    What Are Modular Jacks with Transformers?

    Modular jacks with transformers are network interface connectors that combine an RJ45 port with integrated isolation transformers (magnetics). The transformer component provides electrical isolation, reduces signal noise, and protects equipment from voltage spikes, while the modular jack ensures a standardized interface for Ethernet cabling. These components are essential for maintaining signal integrity in network installations and are widely used in industrial, commercial, and telecom applications.
