What are the key features of TFM-146-22-FM-D-A-P-TR?
- 0.050" (1.27 mm) pitch dual-row female terminal strip with 46 positions per row providing 92 total contacts for ultra-dense board-to-board signal routing
- Tiger Eye high-reliability contact design with 4-point wiping action ensuring consistent low-resistance mating over thousands of insertion cycles
- Tape-and-reel (TR) format and surface-mount footprint supporting automated pick-and-place assembly in high-volume production environments
What is TFM-146-22-FM-D-A-P-TR used for?
The TFM-146-22-FM-D-A-P-TR is engineered for high-density mezzanine board stacking in defense electronics, telecommunications line cards, and industrial computing modules where 92 signals must be routed reliably at 1.27 mm pitch. The female Tiger Eye contacts mate directly with corresponding TFM or TSM series male strips, enabling modular daughter-card architectures with repeatable interconnect performance down to milliohm-level contact resistance. Its compact form factor and SMT compatibility make it an excellent choice for FPGA expansion boards and high-channel-count data acquisition systems.

Frequently Asked Questions
How many total contacts does TFM-146-22-FM-D-A-P-TR provide and at what pitch are they spaced?
The TFM-146-22-FM-D-A-P-TR is a dual-row female connector with 46 positions per row, totaling 92 contacts arranged at 0.050" (1.27 mm) pitch. This high-density layout allows routing of up to 92 signals or mixed signal-and-power lines within a footprint significantly smaller than equivalent 2.54 mm pitch connectors.
For a defense avionics mezzanine card requiring high mating cycle reliability, how does Tiger Eye technology in TFM-146-22-FM-D-A-P-TR help?
SAMTEC's Tiger Eye contact system uses a 4-point wiping contact geometry that distributes insertion force evenly, reducing contact wear per cycle compared to single-point designs. This allows the TFM-146-22-FM-D-A-P-TR to maintain contact resistance below 20 mΩ across hundreds of mating cycles, meeting the reliability demands of avionics LRU (Line Replaceable Unit) modules that are routinely swapped during maintenance at temperatures ranging from -55°C to +125°C.
How does TFM-146-22-FM-D-A-P-TR compare to SAMTEC's TFM-144-series connectors when selecting between high pin-count options?
The TFM-146-22-FM-D-A-P-TR offers 92 total contacts (46 per row) versus the TFM-144 series' 88 contacts (44 per row), making it the choice when the design requires at least 4 additional signal lines. Both share the same 0.050" (1.27 mm) pitch and Tiger Eye reliability, so the selection typically comes down to pin-count margin: TFM-146 adds one extra column pair per row while maintaining nearly identical board footprint dimensions.
