What are the key features of SEAM-40-11.0-S-10-2-A-K-TR?
- 40-position single-row mezzanine connector with 11.0 mm stack height, enabling precise board-to-board separation in high-density FPGA, compute, and RF module stacks
- Gold (30 µin) over Nickel (50 µin) mating contacts with SAMARRAY and ELP technologies for superior signal integrity and reliable retention across thousands of mating cycles
- Keying (K) and PEG board-mount feature prevent mismating and ensure accurate 2.196-inch body alignment during automated PCB assembly with tape-and-reel (TR) packaging
What is SEAM-40-11.0-S-10-2-A-K-TR used for?
The SEAM-40-11.0-S-10-2-A-K-TR is designed for high-density mezzanine board stacking applications in FPGA development systems, server blade modules, and advanced telecommunications line cards where 40 signals must be routed between boards at an 11.0 mm stack height. Its SAMARRAY contact arrangement and ELP technology deliver consistent impedance and low crosstalk across data rates commonly encountered in high-speed digital designs. Tape-and-reel packaging supports automated SMT assembly in high-volume production of networking and embedded computing hardware.

Frequently Asked Questions
What stack height does the SEAM-40-11.0-S-10-2-A-K-TR provide, and how does this affect mezzanine module design?
The SEAM-40-11.0-S-10-2-A-K-TR provides an 11.0 mm board-to-board stack height, which determines the mechanical clearance between the mother board and mezzanine card. This 11.0 mm gap accommodates tall components such as inductors, large capacitors, or heat sinks up to 9 mm tall on the lower board, giving designers flexibility in component selection for compact FPGA or compute module stacks.
How do SAMARRAY and ELP technologies in the SEAM-40-11.0-S-10-2-A-K-TR improve signal quality at high data rates?
SAMARRAY arranges the 40 contacts in a controlled impedance array that minimizes crosstalk between adjacent signal pairs, while ELP (Eyelet Locking Pin) provides a robust mechanical lock that maintains contact normal force after repeated mating cycles. Together, these technologies support differential signal pairs at data rates up to 20 Gbps per lane, making the connector suitable for PCIe, SATA, and high-speed serial interfaces in server and telecom modules.
When is the SEAM-40-11.0-S-10-2-A-K-TR a better choice than a lower stack-height SEAM variant for mezzanine designs?
The 11.0 mm stack height variant is chosen when components on the host board are taller than 8 mm or when thermal management hardware such as a 10 mm heat spreader must fit between the two mated boards. Shorter SEAM variants (e.g., 4 mm or 6 mm) save height in low-profile enclosures, but the 11.0 mm version gives the necessary clearance for high-power FPGAs with attached heat sinks in 1U rack or ruggedized module designs.
