Frequently Asked Questions
How many pins does the TFM-138-03-SM-D-LC have, and what pitch does the contact grid use?
The TFM-138-03-SM-D-LC features 76 pins arranged in two rows of 38, using a standard 1.27 mm pitch grid common to the SAMTEC Tiger Eye series. This dual-row surface mount layout enables high-density PCB-to-PCB connections in space-constrained designs such as embedded processor modules and backplane daughtercard assemblies.
What is the operating temperature range of TFM-138-03-SM-D-LC and how does it suit industrial designs?
The TFM-138-03-SM-D-LC is rated for operation from -55°C to +125°C, making it well suited for industrial and military-grade embedded computing boards that must function across wide thermal environments. Its 76-pin surface mount design simplifies automated PCB assembly while maintaining reliable board-to-board signal integrity.
When would a PCB designer select TFM-138-03-SM-D-LC over lower pin-count Tiger Eye connectors for a parallel bus interface?
A designer selects the TFM-138-03-SM-D-LC when an interface requires all 76 pins for parallel buses, high-channel-count signal routing, or combined power and signal paths rather than a 40-pin or 60-pin variant. The locking clip (LC) option adds mechanical retention beyond a friction fit, which is critical in applications subject to vibration where connector separation could disrupt system operation.
