Frequently Asked Questions
What position count and pitch does TFM-137-12-SM-D-A-P-TR provide for board-to-board wiring?
The TFM-137-12-SM-D-A-P-TR provides 74 positions across 2 rows with a 0.050 inch (1.27 mm) pitch. This dual-row layout delivers 74 individual signal connections within a compact SMT footprint, making it ideal for board-to-board applications where routing density and connector count reduction are design priorities.
Is TFM-137-12-SM-D-A-P-TR compatible with standard SMT reflow processes?
Yes, the SM designation on TFM-137-12-SM-D-A-P-TR indicates a surface-mount termination style compatible with standard SMT reflow soldering. The connector can be processed through lead-free reflow profiles peaking at up to 260°C, following IPC J-STD-001 guidelines, and the TR tape-and-reel format supports automated placement at standard machine pick speeds.
When would a designer choose TFM-137-12-SM-D-A-P-TR over a lower-position-count Tiger Eye connector?
A designer selects TFM-137-12-SM-D-A-P-TR when 74 parallel signal lines need to be interconnected in a single connector at 1.27 mm pitch, which reduces the total connector count on the PCB compared to using multiple smaller 20- or 40-position alternatives. Consolidating to one 74-position connector also simplifies PCB routing, lowers BOM complexity, and eliminates 74 additional solder joints that multiple smaller connectors would require.
