The 3.00 mm mating pitch sets the board footprint and the per-contact current ceiling — with gold on the mating face (15.0 µin) and tin on the solder post (100.0 µin), the contact interface is built for repeated mating cycles without corrosion creeping in. The square male pins (brass) mate with standard Micro MATE-N-LOK receptacle crimp contacts. Rated 250 V, with current depending on the wire gauge in the mating half. ## Locking ramp and solder retention — vibration and reflow anchors The shrouded 4-wall housing carries a locking ramp that clicks the header into the receptacle — no secondary latch needed for moderate vibration environments. The 9.25 mm insulation height gives the receptacle enough clearance for wire dress above the board.","metaTitle":"3-794637-4 TE Connectivity Micro MATE-N-LOK Header, 4 Pos","metaDescription":"3-794637-4 TE Connectivity AMP Connectors Micro MATE-N-LOK header, 4 circuits, 3.00 mm pitch, SMT, gold mating contacts.
