The 0.303\" (7.70 mm) mating length provides enough wipe for the receptacle contact to clean the tin surface on insertion. Above 85°C ambient, derate the 7.5 A per the housing material curve — the polyamide (nylon) loses mechanical strength as it approaches its continuous-use ceiling.","metaTitle":"1744489-3 TE Connectivity Header, 3 Pos, 3.96mm","metaDescription":"1744489-3 TE Connectivity Economy Power header, 3 circuits, 0.156\" pitch, 7.5 A, tin plating, friction lock, UL94 V-0.
