Frequently Asked Questions
What pitch and pin count does the TFM-144-05-H-D-LC offer for high-density board connections?
The TFM-144-05-H-D-LC provides a 0.050-inch (1.27 mm) pitch with 144 positions per row in a dual-row configuration, yielding 288 total pins. This high pin density allows dense signal routing between stacked PCBs in compact embedded systems and telecom line cards where board space is at a premium.
In what scenarios is the low-clearance (LC) variant of the TFM-144-05-H-D-LC preferred over standard-height alternatives?
The LC (low-clearance) designator indicates a reduced mated stack height, making the TFM-144-05-H-D-LC ideal for applications where 2 mm or less of vertical clearance is available between PCBs. Typical use cases include slim portable instruments, mezzanine modules in 1U rack equipment, and compact SBC stacking arrangements where overall assembly height is tightly constrained.
How does the Tiger Eye contact design in the TFM-144-05-H-D-LC improve mating reliability compared to standard beam contacts?
The Tiger Eye contact system uses a double-wipe wiping action across gold-plated (typically 30 µin gold over 50 µin nickel) surfaces, maintaining contact resistance below 20 mΩ even after repeated mating cycles. This double-wipe mechanism displaces contaminants and oxide layers, providing more reliable electrical continuity in high-cycle test environments and long-life industrial equipment.
Is the TFM-144-05-H-D-LC suitable for rapid procurement, and what are the lead-time expectations?
SAMTEC's TFM series is generally stocked or available through Tiger Buy with lead times as short as 1 week. The TFM-144-05-H-D-LC supports worldwide shipping from distribution, making it accessible for production builds needing fast turnaround. Volume pricing and custom tape-and-reel packaging options are also available for higher-quantity orders.
