Frequently Asked Questions
What is the pitch and total contact count of the TFM-149-12-SM-D-A-P-TR?
The TFM-149-12-SM-D-A-P-TR uses a 0.050-inch (1.27 mm) pitch with a dual-row configuration providing 49 positions per row, for a total of 98 contacts. This high-density layout is intended for board-to-board interconnects requiring many signal lines in a compact surface-mount footprint.
Which high-reliability system designs are best served by the Tiger Eye contact technology in the TFM-149-12-SM-D-A-P-TR?
Aerospace electronics, defense avionics, and industrial test equipment are primary targets for the Tiger Eye terminal strip, as these applications require contact resistance stability below a few milliohms even after repeated mating. The 1.27 mm pitch and dual-row SMT format support high-speed differential pairs and power pins across 98 contacts in a single connector.
How does the surface-mount termination of TFM-149-12-SM-D-A-P-TR differ from through-hole versions of similar terminal strips?
The SM (surface-mount) termination style solders directly to pads on the PCB surface, eliminating the need for drilled through-holes and enabling use on boards where via drilling is restricted or expensive. This reduces PCB layer count requirements and allows placement on both sides of the board, supporting denser layouts at 1.27 mm pitch compared to through-hole alternatives requiring ~1.5 mm hole spacing.
