0854-2X6R-66-F is a 2X6 gigabit MagJack integrated connector module designed for VoIP and Ethernet networking applications. It features four transformer pairs with 1CT:1CT ±2% turns ratio, a differential common mode inductance of 350µH minimum at 100kHz/100mVRMS with 8mA DC bias, and insertion loss specifications ranging from -0.5 dB to -1.2 dB across frequencies from 0.1MHz to 125MHz. The module provides 2250 VDC isolation voltage and complies with IEEE 802.3 isolation requirements, with common mode to common mode rejection of -30 dB minimum and common mode to differential mode rejection of -35 dB minimum. Constructed with a thermoplastic PBT housing rated UL 94V-0 and featuring 50 micro-inch hard gold plated contacts, this RoHS compliant component supports balanced DC line current up to 350 mA at 57 VDC continuous. It is ideal for high-speed networking equipment requiring integrated magnetics and robust signal integrity.
