Product details

TE 1888251-3 — 4-Port Shielded RJ45 Jack, Press-Fit Termination

The TE Connectivity 1888251-3 is a 4-port ganged modular jack with 8P8C (RJ45) contacts, designed for Cat5e Ethernet applications.

Press-Fit Termination and Board Integration

Press-fit termination eliminates the soldering step — the compliant pin barrel cold-deforms into the plated through-hole, creating a gas-tight joint. This suits high-reliability backplane assemblies where rework must be clean and thermal stress on the board is undesirable. Board edge, panel mount, and through-hole mounting options give the layout engineer flexibility in enclosure design.

Cat5e Rating and Shielding

Rated for Cat5e performance.
