Board-to-Board or Cable Header at 0.100" Pitch
The 7-146277-0: The unshrouded, push-pull fastening style means it mates with standard AMPMODU receptacles or IDC sockets, and the breakaway construction lets you snap it to a shorter length if your BOM calls for fewer positions. At 3 A per circuit, the temperature rise stays within the LCP housing's UL94 V-0 rating — fine for signal-level interconnects and low-power distribution inside equipment enclosures.
Gold Mating Finish for Repeated Mating Cycles
The post (solder tail) is tin-plated at 100.0 µinch (2.54µm), which wets well during wave or hand soldering. That post length is a standard through-hole dimension for a 1.6mm-thick PCB — the pin protrudes enough for a clean solder fillet on the bottom side without bottoming out in the receptacle.
