The SFSD-40-28C-H-03.25-DR-NUS is a high-density, 40-position (2x20), double-row female socket from Samtec's Tiger Eye™ series. This connector features a 0.050" (1.27 mm) pitch, a through-hole termination style, and a gold-plated contact system. The 'C' in the part number indicates a shrouded design to protect the pins. The 'H' signifies a 0.235" (5.97 mm) tail length, and '03.25' references the stack height in inches, measured from the board surface to the top of the connector. The 'DR' indicates a double row configuration and 'NUS' denotes a no-pick-up-system feature.

Additional Details

The Tiger Eye™ contact system is designed for high reliability and durability. The gold plating on the contacts ensures optimal conductivity and resistance to corrosion, making this connector suitable for demanding environments. The shrouded body provides additional protection to the contacts, preventing damage during handling and mating. The SFSD series is known for its robust construction and consistent performance, making it a popular choice for various board-to-board interconnect applications. The 'NUS' option indicates that it lacks the standard pick-up system, generally used in automated assembly.
