PTC1111-90

YCL Description The YCL LAN modular Jack has been specifically designed for implementation of fast Ethernet NIC Application . With high voltage isolation, optimized rise time, wideband width and stable inductance, the transformer integrated the module provide excellent performance as an analog interface. Common mode choke have been designed to significantly reduce common mode choke level which may contribute EMI emission. YCL LAN modular jack provide the system designer the opportunity of reducing pcb space.
