What are the key features of TFM-128-01-F-D-A-P-TR?
- 28-position dual-row Tiger Eye terminal strip at 0.050 inch pitch in tape-and-reel (TR) packaging for automated SMT assembly
- Two-point redundant Tiger Eye contact geometry achieves contact resistance typically below 20 milliohms for high-reliability interconnect
- Anti-rotation peg (P suffix) locks the connector body to the PCB, preventing movement during reflow and field vibration
What is TFM-128-01-F-D-A-P-TR used for?
The TFM-128-01-F-D-A-P-TR is engineered for high-density SMT board-to-board interconnect in aerospace, defense avionics, and high-performance industrial computing platforms that demand consistent signal integrity across all 56 contacts. The tape-and-reel packaging integrates seamlessly into automated pick-and-place production lines, reducing placement error at 0.050 inch pitch. Anti-rotation pegs and the Tiger Eye contact system together ensure mechanical stability and reliable electrical performance even under continuous mechanical stress or thermal cycling.

Frequently Asked Questions
What does the TR suffix in TFM-128-01-F-D-A-P-TR indicate, and how does it benefit high-volume PCB assembly?
The TR suffix designates tape-and-reel packaging, supplying the TFM-128-01-F-D-A-P-TR on a continuous carrier reel compatible with automated pick-and-place equipment. This eliminates manual placement of a 56-contact, 0.050 inch pitch dual-row connector, improving placement accuracy and throughput on high-volume SMT production lines processing hundreds of boards per hour.
How many total contacts does the TFM-128-01-F-D-A-P-TR provide, and what signal bus widths does that support?
The TFM-128-01-F-D-A-P-TR delivers 56 total contacts across 2 rows of 28 positions at 0.050 inch (1.27 mm) pitch. This capacity supports 32-bit data buses with separate address, power, and ground lines, or 56-channel analog or digital I/O configurations in data acquisition modules, FPGAs, and embedded controller boards.
What role does the anti-rotation peg (P suffix) play during reflow soldering of TFM-128-01-F-D-A-P-TR?
The anti-rotation peg mechanically anchors the TFM-128-01-F-D-A-P-TR body to the PCB through a locating hole, preventing the connector from shifting or rotating when solder paste liquefies during reflow at temperatures up to 260 °C. This ensures all 56 contacts remain aligned to their pads throughout the reflow profile, reducing solder bridging and misalignment defects.
When should a designer choose TFM-128-01-F-D-A-P-TR over a 0.100 inch pitch alternative for the same signal count?
At 0.050 inch pitch, the TFM-128-01-F-D-A-P-TR occupies roughly half the PCB footprint of a 0.100 inch pitch connector carrying 56 signals. Designers targeting board densities above 40 contacts per square centimeter or laying out multi-layer HDI boards should choose this part to conserve routing area, particularly in compact aerospace and portable defense electronics where board dimensions are fixed.
