What are the key features of TFM-145-22-F-D-A-P-TR?
- 45-position dual-row female contact layout at 0.050 inch (1.27 mm) pitch provides 90 total signal connections in a compact SMD footprint
- Tiger Eye dual-beam female contacts maintain consistent contact force and low resistance below 20 mΩ across repeated mating cycles
- Tape-and-reel (-TR) SMD packaging with -A-P options ensures precise component orientation for high-speed automated assembly and reflow soldering up to 260°C
What is TFM-145-22-F-D-A-P-TR used for?
The TFM-145-22-F-D-A-P-TR is designed for high-density mezzanine card, FPGA expansion, and multi-signal backplane interconnects where 90 contacts must pass through a minimal PCB area. Its female dual-row contact arrangement mates with corresponding male TFM or TSM pin headers, enabling modular stacking of processor, memory, and I/O boards in telecommunications and defense electronics. The SMD footprint and reel packaging also facilitate high-throughput automated assembly of data acquisition systems and industrial computing modules.

Frequently Asked Questions
How many total contact positions does TFM-145-22-F-D-A-P-TR support and how are they arranged?
The TFM-145-22-F-D-A-P-TR has 45 positions per row in a dual-row layout, yielding 90 total contacts on a 0.050 inch (1.27 mm) pitch. This configuration allows routing of 90 single-ended signals or 45 differential pairs through a single connector, enabling high pin-count interfaces in FPGA, networking, and embedded computing applications without excessive board area.
What mating connector pairs with TFM-145-22-F-D-A-P-TR and how reliable is the connection?
The -F (female) contact designation means TFM-145-22-F-D-A-P-TR accepts male pin headers from SAMTEC's TSM or TFM male series on the same 0.050 inch (1.27 mm) pitch. The Tiger Eye dual-beam female contact applies consistent normal force, maintaining contact resistance below 20 mΩ and reliable mating performance for 200 or more engagement cycles in demanding industrial and aerospace board-swap scenarios.
How does TFM-145-22-F-D-A-P-TR handle high-volume automated assembly requirements?
The -TR suffix confirms tape-and-reel packaging, making the connector compatible with standard pick-and-place machines that handle SMD components. The surface-mount termination supports lead-free reflow soldering at peak temperatures up to 260°C per J-STD-020, enabling single-pass SMT assembly alongside other board components without requiring separate connector insertion or hand-soldering steps.
How does TFM-145-22-F-D-A-P-TR compare to TFM-144-22-F-D-A-P-TR in terms of signal capacity?
TFM-145-22-F-D-A-P-TR provides 45 positions per row for 90 total contacts, while TFM-144-22-F-D-A-P-TR provides 44 positions per row for 88 total contacts. The 145 variant adds 2 extra contacts within a body only 1.27 mm longer per row. When interface definitions require exactly 90 pins — for instance a 45-pair differential bus — the TFM-145 variant accommodates the full signal count without requiring a second connector.
