The KLA1T109-43LF is a single-port 1000BASE-T RJ45 MagJack (Integrated Magnetics Connector, IMC) designed for Gigabit Ethernet networking equipment. This 1×1 right-angle RJ45 connector integrates Ethernet isolation transformers, common-mode filtering, impedance matching resistors, and a high-voltage capacitor into a compact package, significantly reducing PCB space while improving EMI performance.
Compliant with IEEE 802.3ab and FCC requirements, the KLA1T109-43LF supports 1000BASE-T transmission over Category 5 UTP cable and features dual integrated LEDs for link and activity indication. With 1500Vrms isolation, 350μH minimum OCL, and 750 mating cycles, it is an ideal solution for enterprise networking, industrial Ethernet, IP communication devices, and embedded networking systems.
