LPJD4011DNL4 IR Reflow Vertical RJ45 Jack With 10/100Base-T Magnetics
LPJD4011DNL4 THR Vertical RJ45 Connector Overview
LPJD4011DNL4 is a vertical RJ45 connector developed by LINK-PP INT'L TECHNOLOGY CO., LIMITED, which is essentially positioned as a Through-Hole Reflow (THR) connector with 10/100 magnetic components. It is adapted to Ethernet scenarios, supporting 10/100 Base-T transmission rate, and adopts a 1x1 port design. The contact configuration is 8P8C (complying with the RJ45 Ethernet interface standard), and it is a non-PoE (Power over Ethernet) type. The port has 4 built-in magnetic cores, and the PCB mounting angle is a top-entry type, which can meet the interface requirements of conventional local area network (LAN) devices.
