What are the key features of SEAM-50-03.0-S-06-2-A-K-TR?

  • 300-position open-pin-field array on 0.050" (1.27 mm) pitch enabling maximum signal density for board stacking
  • 30 µin gold over 50 µin nickel contact plating ensuring reliable high-cycle mating in high-speed applications up to multi-GHz
  • SEARAY ELP final-inch SAMARRAY/SEARRAY technology optimized for co-planar high-speed differential signal routing

What is SEAM-50-03.0-S-06-2-A-K-TR used for?

The SEAM-50-03.0-S-06-2-A-K-TR is designed for high-density server blade backplane assemblies, FPGA mezzanine cards, and telecom line card interconnects requiring 300 signal channels at 0.050" pitch. Its SEARAY open-pin-field architecture gives designers full flexibility in assigning high-speed differential pairs, power, and ground at any position in the 300-pin array. Gold-over-nickel contacts maintain signal integrity in multi-gigabit PCIe, Ethernet, and JESD204B interfaces under extended operating cycles.

Frequently Asked Questions

How many signal positions does the SEAM-50-03.0-S-06-2-A-K-TR array support, and what pitch does it use?

The SEAM-50-03.0-S-06-2-A-K-TR provides 300 positions on a 0.050" (1.27 mm) pitch open-pin-field array. This density allows routing up to 150 differential pairs or any combination of high-speed signals, power, and ground within a footprint measuring approximately 2.696 × 0.26 inches on the PCB.

What contact plating specification does the SEAM-50-03.0-S-06-2-A-K-TR use and how does it affect mating cycles?

The SEAM-50-03.0-S-06-2-A-K-TR uses 30 µin (0.76 µm) gold over 50 µin nickel at the mating interface, with tin-over-nickel at the solder termination. The gold mating surface supports hundreds of insertion cycles while maintaining contact resistance well below 50 mΩ, making it suitable for test fixtures and hotplug backplane applications where frequent mating and unmating occurs.

For a high-speed FPGA mezzanine design, how does SEARAY's open-pin-field architecture compare to a fixed-assignment board connector?

SEARAY's open-pin-field design on the SEAM-50-03.0-S-06-2-A-K-TR allows engineers to assign any of the 300 pins to differential pairs, single-ended signals, 3.3 V power, or ground without being constrained by a fixed vendor-defined pinout. This contrasts with fixed connectors such as VITA 57.1 FMC, where differential pairs, clocks, and power rails occupy predefined positions. The flexibility reduces routing congestion on 12-layer FPGA boards and supports custom multi-gigabit channel impedance control at 85 Ω or 100 Ω differential.
