The Amphenol FCI 79821-144HLF is the 44-position, dual-row member of the BERGSTIK® II series — a 0.100" (2.54 mm) pitch unshrouded male header designed for board-to-board stacking and wire-to-board applications where a standard DIP footprint is required. It carries 44 positions loaded all, with a 0.100" row spacing that matches legacy 0.100" grid layouts. Rated 5 A per contact at 110 V, with 30 µ" (0.76 µm) gold or Gold, GXT™ plating on the mating surface over phosphor bronze contacts, it suits signal and moderate-power distribution in industrial control, test equipment, and telecom backplanes.
The 0.100" pitch and row spacing mean this header drops onto a standard 0.100" grid PCB — no custom footprint needed, and it mates with any 0.100" pitch female receptacle or IDC socket.
The overall contact length of 0.730" (18.54 mm) gives a 0.430" (10.92 mm) mating interface and a 0.100" (2.54 mm) insulator height above the board.
