HB/HXB Industrial SMD Discrete LAN Transformers

Pulse Electronics HB/HXB Industrial SMD Discrete LAN Transformers feature dual-port high-density modules with 16-, 24-, 40-, and 48-pin packages with or without Power-over-Ethernet (PoE/PoE+) capability. The transformers meet IEEE802.3 for all Ethernet data rates and 10/100Base-Tx, 1000Base-T, 2.5G/5G, and 10GBase-T requirements. The HB/HXB series provides a 1500V_rms minimum isolation rating between analog and digital for signal integrity and performance. The transformers offer industry-standard SMD case sizes with moisture sensitivity level (MSL) 1 and RoHS compliance. The Pulse Electronics HB/HXB Industrial SMD Discrete LAN Transformers are designed for various industrial networks, electronics, and rugged environment applications.
