5520251-4 Description

Short technical summary and product information.

This is a TE Connectivity 5520251-4 modular jack connector. It features an 8p8c (RJ45) contact arrangement with a single port and single row of contacts. The connector is designed for through hole mounting with a right angle (90°) orientation, making it suitable for edge-mounted applications on PCBs.

 

The jack is unshielded and has a tab direction of down. It includes board lock and panel stop features for secure mechanical retention. The contacts are made of phosphor bronze with a gold finish, providing reliable electrical performance and corrosion resistance. The connector is rated for Category 3 (Cat3) applications, typically used for voice and low-speed data transmission.

 

This connector does not contain an LED indicator. The housing is designed for solder termination. The unshielded variant is cost-effective for applications where EMI shielding is not required. The board lock ensures robust attachment during soldering and assembly.
