Modular Jacks

TE Connectivity's (TE) ERNI Modular Jacks are high-performance connectors that facilitate fast and reliable high-bandwidth connections. These jacks comply with Ethernet standards and feature data rates in the Gigabit range. Modular jacks with integrated receivers save valuable PCB space. These RJ11 and RJ45 jacks are offered in three termination options: through-hole (THT), through-hole reflow (THR), and surface-mount (SMT). ERNI Modular Jacks are shielded for high signal quality and are ideal for use in a variety of industrial and communications applications.
