Key Features
- 100-position dual-row configuration at 0.050" (1.27 mm) pitch for maximum signal density in a 2.625" body length
- Gold-over-nickel contact finish providing high-reliability, low-resistance mating interface with superior corrosion resistance
- Split board-lock mechanism offering mechanical retention to resist vibration and mating forces on the PCB
- Tiger Eye contact design enabling reliable wiping action and consistent electrical contact across all 100 positions
Applications
The TFM-150-32-S-D-LC is designed for high-density board-to-board interconnect applications requiring 100 signal or power connections at a 0.050" pitch on surface-mount PCBs. It is commonly deployed in communications backplanes, server infrastructure cards, and high-performance computing modules where reliable dual-row SMT connectors with mechanical board-lock retention are critical. The Tiger Eye contact design and gold-over-nickel plating ensure consistent signal integrity across multiple mating cycles in demanding environments.

Frequently Asked Questions
How many contact positions does the TFM-150-32-S-D-LC provide, and what is the connector body length?
The TFM-150-32-S-D-LC provides 100 contact positions in a dual-row layout at a 0.050" (1.27 mm) pitch, with a body length of 2.625 inches. This makes it one of the highest-density connectors in the SAMTEC TFM series, delivering 100 signal paths within a compact SMT footprint on a single vertical connector.
What does the split board-lock (LC) feature add to the TFM-150-32-S-D-LC in demanding PCB applications?
The split board-lock feature in the TFM-150-32-S-D-LC mechanically anchors the 100-position connector to the PCB through press-fit retention pegs on both ends of the 2.625" body. This prevents the connector from shifting or lifting under vibration or repeated mating forces, maintaining coplanarity of the gold-over-nickel contacts and ensuring consistent electrical performance in high-stress environments.
Which high-performance system designs typically deploy the TFM-150-32-S-D-LC?
The TFM-150-32-S-D-LC is commonly used in communications infrastructure, server backplanes, high-speed data acquisition systems, and FPGA daughtercard interfaces where 100 dual-row connections at 0.050" pitch are needed. The Tiger Eye contact design and gold-over-nickel finish make it well-suited for high-cycle-life applications where signal integrity across all 100 positions must be maintained over thousands of mating events.
How does the gold-over-nickel contact finish of the TFM-150-32-S-D-LC compare to standard tin finishes for reliability?
Gold-over-nickel plating on the TFM-150-32-S-D-LC provides a harder, more corrosion-resistant mating surface than standard tin-plated contacts, resulting in lower and more stable contact resistance across all 100 positions. For high-frequency or sensitive signal applications at 0.050" pitch, the gold finish reduces the risk of fretting corrosion that can develop on tin contacts after repeated mating cycles, extending connector service life in demanding environments.
