Surface-mount termination with shrouded 4-wall housing and a locking ramp — the ramp gives a positive tactile lock against vibration, standard for harness applications where the connection sees movement. 8 A per circuit is the headline current, and it's real — the contact beam and housing are sized for that at the rated temperature rise. Tin on the solder tail (100.0 µin) is standard for the SMT reflow joint.","metaTitle":"Molex Micro-Fit 3.0 430451219, 12-Pos Header, 8 A","metaDescription":"Molex 430451219 Micro-Fit 3.0 SMT header, 12 circuits, 3.00 mm pitch, 8 A, 600 V, gold contacts.
