Frequently Asked Questions
How many contact pins does the TFM-139-32-SM-D-A-P-TR provide and at what pitch for dense PCB layouts?
The TFM-139-32-SM-D-A-P-TR is a dual-row SMT terminal strip with 39 positions per row, providing 78 pins at a 0.050 inch (1.27 mm) contact pitch. This high-density layout suits mezzanine and board-to-board interconnects in compact telecommunications and high-performance computing PCB designs where space is at a premium.
What makes the Tiger Eye contact technology in the TFM-139-32-SM-D-A-P-TR suited for high-cycle mating applications?
The Samtec Tiger Eye contact features a specialized stamped geometry that wipes the mating surface on each connection, removing oxidation and maintaining stable, low contact resistance. Rated for repeated mating cycles at operating currents up to 1 A per contact, all 78 pins deliver reliable performance in test equipment, medical devices, and defense electronics requiring high-reliability interconnects.
When would an engineer specify the TFM-139-32-SM-D-A-P-TR over a standard 0.100 inch pitch connector for a high-density PCB?
The 0.050 inch pitch of the TFM-139-32-SM-D-A-P-TR enables placement of 78 pins in roughly half the PCB area required by a 0.100 inch pitch connector. Engineers choose this terminal strip when board space is critical, such as in FPGA mezzanine cards, backplane systems, and space-constrained defense avionics assemblies requiring a high pin-count surface-mount solution.
