Factory Direct SMD LAN Transformer Ethernet Magnetics Module Support OEM ODM Transformer for Telecom Hardwares. Fully optimized for 100BASE-TX Fast Ethernet protocols, delivering stable 100Mbps data transmission for networking devices. Ultra-small 12.80x6.90x6.50 mm miniature SMT package design, saving maximum PCB space for high-density hardware layouts. Features a highly precise 1CT:1CT transmit and receive turns ratio, ensuring perfect impedance matching with standard PHY chips. Low insertion loss of only 1.1 dB max across the 100KHz to 100MHz range ensures minimal signal attenuation. High return loss of -20dB min at 30MHz effectively eliminates high-frequency reflections and maintains signal clarity. Outstanding crosstalk suppression reaching -45dB at 30MHz prevents inter-channel interference and prevents packet loss. Excellent CMRR performance (-42dB at 30MHz) effectively blocks common-mode noise in harsh electromagnetic environments. Provides 1500Vrms isolation voltage to protect sensitive downstream Ethernet transceiver ICs from line surges. Perfectly suited for IP cameras, smart meters, set-top boxes, PLC modules, gateways, and industrial automation control. Produced under strict factory quality assurance with reliable, long-term manufacturing capacity backed by CoreLogic.
