For a 20 AWG wire, expect around 5-6A per contact; for 18 AWG, up to 7-8A, but always check the terminal datasheet for the derating curve. The header mounts vertically through-hole, with a contact length - post of 0.125\" (3.18mm) — a standard solder-tail length for 1.6mm thick PCBs.","metaTitle":"3-644615-2 TE Connectivity MTA-156 Header, 2 Pos","metaDescription":"TE Connectivity MTA-156 shrouded header, 2 positions, 3.96mm pitch, tin-plated contacts, friction lock, UL94 V-0.
