The NDMB154100 is an integrated magnetics module designed for Power over Ethernet (PoE) and CAT6A high-speed Ethernet applications. It features four differential pairs with magnetics integration, supporting data transmission up to 500 MHz with insertion loss of -2.0 dB maximum at 1–400 MHz and -3.0 dB maximum at 400–500 MHz. The module provides a turn ratio of 1:1±3%, return loss of -22 dB minimum at 1–100 MHz, and common mode rejection ratio of -30 dB minimum at 1–40 MHz. With a current rating of 960 mA for each of the four differential pairs and 1,500 VAC isolation (HIPOT), this RoHS-compliant component is ideal for high-speed network interface applications requiring integrated signal and power delivery.
