Surface Mount Terminal Blocks

140-A-126-SMD 5.00 mm (0.197 in) Spacing   -   2-12 poles Print this page

  • 140-A-126-SMD is an elevator style 5 mm pitch terminal block suitable for SMT (surface mount technology) applications. Flat contact leads provide a large surface area for reliable solder joints. The solder retention devices (SMT anchors) provide high retention force for the terminal block to the PCB. The SMT anchors being mobile within the plastic housing (floating) they ensure a total adaptation to the planar variations of the PCB. This adds to the retention force of the connector to the PCB meanwhile eliminating the CTE (Coefficient of Thermal Expansion) mismatch. The most significant benefit of this design is the protection it provides to the solder joints against stresses encountered in field-installations.

    Material will handle reflow temperatures well without deforming or melting. Product packaging is suitable to pick place automated assembly.

    German Utility Patent 20 2005 014 667.6

You can now convert one more component on your board to a genuine surface mount. You can increase packaging and component density, use both sides of the PCB, reduce and eliminate set-up costs and simplify and streamline your processes. This terminal block features an integrated pick area that allows this product to be picked-and-placed without any additional changes to your process. Its floating anchors (retention elements) compensate for irregularities (non planarity and bumps) on the printed circuit. Its floating anchors (retention elements) compensate for irregularities (non planarity and bumps) on the printed circuit board. The same feature eliminates CTE mismatch with the PCB and thus eliminates stresses on the anchor solder joints thus assuring a long life.
