Termination is surface mount, which means the part reflows onto the board without through-hole holes — a space saver on the back side but one that demands good solder-paste stencil design for the 0.100" pitch.
Tin Contacts, 3 A Rating, and the Temperature Range
Tin-on-tin is the workhorse for moderate-duty signal interconnects — it keeps cost down but the contact resistance can rise after repeated mating cycles. For a board-to-board header that mates once during assembly and stays connected, tin plating is a practical choice. Current rating is 3 A per contact at the listed ambient.
Sourced through independent distribution channels. The part ships in bag packaging per the standard factory package.
