Surface Mount Terminal Blocks

931-SLT-SMD-1.1 3.50 mm (0.138 in) Spacing   -   02-12 poles Print this page

  • US Patent # 6.224.399 B1
    Canadian Patent # 2,307,922
    The 931-SLT-SMD-1.1 is a 3.5 mm pitch pin strip header, low profile, with pins that are 1.1 mm diameter at the plug end with a base (nail head) solder lead of 1.9 mm in diameter.
    The high temperature resistant resin molding and the matte tin & nickel plated copper alloy pin meet RoHS SAC (tin, silver, copper) soldering temperature and tin whisker mitigation requirements.
    Pin strips equipped with removable pick caps are packed in deep embossed tape and reel, suitable for auto-loading pick and place processes. They can also be supplied loose in cartons for hand placement.
    Excellent coplanarity: better than 0.13 mm.

You can now convert one more components on your board to genuine surface mount. You can increase packaging accuracy and component density, use both sides of the PCB, reduce and eliminate set-up costs and simplify and streamline your processes. The patented 931-SLT-SMD-1.1 "nail head" pin design ensures a secure and reliable contact with the printed circuit board. Recommended solder pad (land) is 2.0 to 2.2 mm in diameter or equivalent shape & area. The 0.13 mm co-planarity tolerance of this pin strip allows reliable soldering to PCB approaching zero open circuit defects for this characteristic and its effects. Removable pick caps ensure automated pick & place-ability. Consult our “Tape & Reel Data?table within our Technical Information section for details.
