Without it, the solder joints take the full strain and can crack over repeated mate/unmate cycles. The shrouded 4-wall design protects the male pins from bending during handling and guides the mating receptacle into alignment — a half-turn loose on the locking ramp is a dropout, so the positive latch is your insurance against vibration loosening. ## Mating half and termination checklist This header mates with the Mini-Universal MATE-N-LOK receptacle housing (sold separately). Termination is through-hole solder — the 0.175-inch post length gives enough stand-off for wave solder or hand-solder, and the tin-lead finish on the post wets well with standard solder alloys. The mating face uses the same tin-lead finish, rated for moderate mating cycles; if your application cycles the connector more than a few dozen times, consider the gold-plated sibling in the same series. ## Sourcing and lifecycle status Note that this part is RoHS non-compliant due to the tin-lead contact finish. If your assembly requires RoHS compliance, check the lead-free (gold or tin) variants in the same series.","metaTitle":"770743-1 TE Mini-Universal MATE-N-LOK Header 10 Pos 4.14mm","metaDescription":"770743-1 TE Connectivity AMP Connectors Mini-Universal MATE-N-LOK header, 10 positions, 4.14mm pitch, shrouded, board lock.
