Samtec SEAM Series Straight Surface PCB Header, 320 Contacts, 1.27 mm Pitch, 8 Row, Shrouded SEAM-40-03.5-S-08-2-A-K-TR

Samtec SEAM-40-03.5-S-08-2-A-K-TR is a high-performance SEAM Series Straight Surface PCB Header designed for robust board-to-board interconnections. It features a total of 320 contacts arranged in 8 rows with a precise 1.27 mm pitch. The connector is shrouded, providing added protection and alignment during assembly. Constructed with a Liquid Crystal Polymer housing, it offers excellent durability and thermal stability across operating temperatures ranging from -55°C up to 125°C. The male contacts are made from copper alloy and plated with 0.76 μm gold to ensure low contact resistance of approximately 5.5 milliohms and reliable signal integrity.

This PCB header supports currents up to 2.7A and a maximum operating voltage of 240V, making it suitable for demanding electronic applications. Its use of Samtec's SEARAY™ high-speed interconnect technology enables signal frequencies up to 12.5 GHz at -3 dB, beneficial for high-speed data transfer requirements. The solder termination type provides secure mechanical and electrical connection to the PCB surface mounting pads.

The product is ideal for industrial, manufacturing, communication, and electronic assembly environments requiring high density, reliable, and fast board stacking connectivity. The shrouded design helps prevent misalignment during mating, improving manufacturing yield rates.
