Compact embedded computing and controller modules
High-density data and control interfaces on multilayer PCBs
Signal socketing in IoT, handheld and portable electronics
Surface-mount board stacking where vertical height is limited
Highlights:
1.27mm dual row SMT female header, 38 positions, vertical orientation
Low-profile 4.3mm base / 4.6mm height above PCB for dense layouts
Phosphor bronze contacts with gold over nickel on mating and solder areas
Electrical ratings: 1.0A/contact, ≤20mΩ contact resistance, ≥1000MΩ insulation, 500V AC/DC withstand
PA9T UL94V-0 flame-retardant housing; operating range -40°C to +105°C
IR-reflow capable: 260°C for 10s or 230°C for 30–60s, tape & reel packaging
Series supports versions with or without PCB locating posts; this part is supplied without locator post
1.27mm dual row SMT female header is a fine-pitch, surface-mount receptacle designed for high-density board-to-board signal interconnects. This 1.27mm dual row SMT female header provides two parallel rows of square contacts on a 1.27mm (.050″) grid, with SMT pad dimensions of approximately 0.50 × 0.15mm to match standard reflow footprints. The 38-circuit configuration delivers a compact solution for dense multilayer PCBs where vertical height and footprint must be tightly controlled.
