The 5-146250-2: This is a 4-position, dual-row unshrouded header from the AMPMODU Mod II series, designed for board-to-board or cable interconnect with a standard 0.100" (2.54mm) pitch on both rows and between rows. Through-hole solder termination with a 0.125" (3.18mm) post length suits standard PCB thicknesses; the overall contact length of 0.533" (13.55mm) gives a solid 0.318" (8.08mm) mating interface.
Current, temperature, and flammability envelope
Rated 3 A per contact — typical for a 0.100" pitch signal header with tin-plated contacts; the limiting factor is the temperature rise in the LCP housing at full load. Operating temperature range of -65°C to 105°C covers most commercial and industrial environments; the UL94 V-0 rated LCP housing meets the flammability requirement for equipment inside an enclosure. Both the mating and post contact finishes are 100.0µin (2.54µm) tin.
