Product details

50-Position Signal-Density Header for Mezzanine Stacks

The 73547-125LF is a 50-position, dual-row board-to-board header from the Rib-Cage III series. If your enclosure has a tight z-height budget, that number sets the clearance for components under the top board. Rated 1 A DC per contact, this is a signal-density interconnect, not a power rail.

Shrouded Housing and SMT Termination

Surface-mount termination with tin-plated solder tails (100 µinch) — the tails are designed for reflow assembly.

It ships in tube packaging.
