You can now convert one more component on your board to a 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 971-SLR-SMD "nail head" pin design ensures a secure and reliable contact with the printed circuit board. The 0.13 mm co-planarity tolerance of this pin strip allows reliable soldering to PCB approaching zero defects for this characteristic and its effects. Plastic thermo resistant caps ensure automated pick & place-ability for both odd and even pole versions.
