What are the key features of TFM-142-12-F-D-A-P-TR?
- Tiger Eye dual-row contact system at 0.050 inch (1.27 mm) pitch delivers 84 pins in a compact footprint, maximizing signal density for high-speed board-to-board interfaces
- Through-hole (F suffix) termination offers superior mechanical retention strength compared to surface mount alternatives, ensuring reliable solder joints in vibration-prone environments
- Tape-and-reel (TR) packaging combined with polarized keying (-A-P) prevents assembly errors and supports automated pick-and-place manufacturing for high-volume production
What is TFM-142-12-F-D-A-P-TR used for?
The TFM-142-12-F-D-A-P-TR is designed for high-density through-hole board-to-board and mezzanine card interconnect in defense, aerospace, and industrial computing applications. Its 84-pin dual-row Tiger Eye contact system at 0.050 inch pitch accommodates complex signal buses on FPGA carrier boards, processing modules, and ruggedized backplane systems. The polarized keying and through-hole mounting provide both assembly error prevention and mechanical robustness in harsh operating environments.

Frequently Asked Questions
What is the pin count and pitch of TFM-142-12-F-D-A-P-TR, and how does this enable high-density interconnect?
The TFM-142-12-F-D-A-P-TR provides 84 pins in a dual-row configuration at 0.050 inch (1.27 mm) pitch. Compared to 0.100 inch pitch connectors, this doubles the signal count per unit board length, enabling complex FPGA I/O buses, high-speed memory interfaces, and multi-channel sensor connections within a footprint half the size of standard pitch alternatives.
Why is through-hole termination (F suffix) preferred over SMT for TFM-142-12-F-D-A-P-TR in ruggedized applications?
Through-hole solder joints on the TFM-142-12-F-D-A-P-TR provide an anchor through the PCB substrate, delivering tensile and shear strength far exceeding that of surface mount solder fillets. For 84-pin connectors in systems exposed to shock loads exceeding 50 g or continuous vibration, through-hole termination prevents pad lift and solder fatigue that could cause intermittent open circuits.
How does the -A-P polarized keying prevent assembly errors when populating TFM-142-12-F-D-A-P-TR on high-speed PCBs?
The -A-P polarization feature adds a physical key to the connector housing that only mates correctly in one orientation, preventing a 180-degree reversal of the 84-pin signal assignment. On high-speed digital boards where signals may carry voltages from 1.8 V to 5 V, an incorrect reversal could permanently damage ICs connected to the bus, making polarized keying a critical design safeguard.
