Frequently Asked Questions
What pitch and contact count does the SAMTEC SFM-134-T2-L-D-A-K-TR use, and what signal density does it support?
The SFM-134-T2-L-D-A-K-TR features 68 contacts arranged in a dual-row layout at 0.050" (1.27 mm) pitch, providing very high signal density in a compact SMT footprint. At 68 pins, it can support up to 34 differential pairs or a combination of power, ground, and high-speed signals in FPGA and processor mezzanine board designs.
For high-speed PCB designs, how does the 0.050" pitch of the SFM-134-T2-L-D-A-K-TR affect signal integrity compared to 0.100" pitch connectors?
The 0.050" (1.27 mm) pitch halves the connector length compared to a 0.100" pitch equivalent at the same pin count, reducing stub lengths and parasitic inductance. This makes the SFM-134-T2-L-D-A-K-TR better suited for signal frequencies above 1 GHz, where tight pitch minimizes crosstalk and impedance discontinuities in differential signal routing.
In what reliability-critical applications is the SFM-134-T2-L-D-A-K-TR preferred over standard SMT socket connectors?
The high-reliability (T2 grade) designation targets applications requiring extended mating cycles typically exceeding 500 insertions, along with resistance to vibration and thermal cycling from -55°C to +125°C. Defense electronics, industrial robots, and avionics data acquisition boards benefit from the gold-plated contacts and reinforced SMT retention of this 68-position connector.
