NSH series, 4-position single-row header, 1.00 mm pitch, surface-mount right-angle, shrouded 4-wall with latch holder, rated 1 A at 50 V.","salesMarkdown":"## Board fit and mounting orientation The SM04B-NSHSS-TB is a 4-position, single-row header on 1.00 mm pitch, terminated via surface-mount right-angle solder tails. The right-angle orientation routes the mating cable parallel to the PCB, saving z-height in tight enclosures. ## Rated current and voltage — signal-level duty Rated 1 A per contact at 50 V — this is a signal interconnect, not a power header. The tin-plated contacts (mating and post) are suited for moderate mating cycles in controlled environments. Operating temperature range is -25°C to 85°C, with a UL94 V-0 nylon housing. ## Mating interface and locking The header is fully shrouded on all four sides, guiding the mating NSH receptacle and protecting the male pins from damage during handling. A latch holder on the top locks the mated pair, providing vibration resistance. ## Sourcing and lifecycle RoHS non-compliant per the listing — verify your local compliance requirements before committing the BOM line.","metaTitle":"SM04B-NSHSS-TB JST 4-Pin 1.00 mm Right-Angle SMT Header","metaDescription":"JST NSH series 4-position header, 1.00 mm pitch, right-angle SMT, shrouded 4-wall, latch holder, 1 A, 50 V, UL94 V-0.
