Wurth Elektronik RJ45 Connector, Female, Surface Mount, Cat3, Nickel Plated Brass Shield, 1 Port, 8 Way 634008138121

The Wurth Elektronik 634008138121 RJ45 Connector is engineered to deliver robust Ethernet connectivity in networking and telecommunications systems. This female modular jack features a Cat3 rated interface, enabling reliable data transmission in environments where category 3 cabling is common, such as legacy LAN infrastructure, industrial networking panels, and telecom installations. With one port and an 8-way configuration, it is suitable for single-channel Ethernet connections, providing flexibility for both new designs and replacement needs.

The connector's surface mount (SMT) design streamlines assembly and improves reliability by ensuring secure and precise positioning on printed circuit boards. Its vertical orientation offers top-entry access, which is ideal for rack-mount switches, desktop network modules, and compact communication devices where board real estate is at a premium.

Durability is enhanced by the use of a nickel plated brass shield, delivering effective electromagnetic interference (EMI) protection essential for high-speed data applications. Gold plated contacts made from copper alloy deliver low contact resistance and maintain optimal signal integrity through repeated insertions and withdrawals, rated for up to 500 mating cycles.

The connector supports a working voltage up to 120 V AC and withstanding voltage up to 1000 V AC. It is also RoHS compliant, meeting current environmental standards for lead-free and hazardous material restricted products. Designed to operate in temperatures ranging from -40°C to 85°C, this component is suitable for both commercial and industrial settings - including data centers, factory automation systems, and structured cabling environments.

Installation is straightforward thanks to the solder termination style, delivering stable and long-lasting electrical connections. The compact housing (15.24 mm length, 15.15 mm width, 12.7 mm depth) conserves PCB space and integrates easily into high-density layouts. A nickel plated brass shield fully encompasses the connector for enhanced mechanical and electrical performance.

The Wurth Elektronik 634008138121 is part of the 634008 series and is widely used in Ethernet patch panels, PoE (Power over Ethernet) devices, serial device servers, and other modular communications hardware where reliability and signal purity are critical. With its rugged construction, broad compatibility, and proven materials, this connector is the preferred choice for updated and new infrastructure projects requiring Category 3 Ethernet interfacing.
