Frequently Asked Questions
How many contact positions does the TSM-139-03-H-DV-P-TR provide, and at what pitch are they spaced?
The TSM-139-03-H-DV-P-TR provides 78 total contact positions arranged in a dual-row configuration at standard 0.100" (2.54 mm) pitch. This spacing is compatible with a wide range of mating headers and ribbon cable connectors, making it interchangeable with industry-standard 2 × 39 pin PCB interconnect solutions.
For a backplane design requiring 60+ parallel bus lines, how does the dual-row layout of the TSM-139-03-H-DV-P-TR optimize board space?
The dual-row arrangement at 0.100" pitch fits 78 contacts in a single connector measuring approximately 98.6 mm in length, compared to roughly 197 mm needed for a single-row equivalent carrying the same 78 signals. This 50% length reduction frees significant PCB edge space in backplane designs, allowing additional connectors or functional circuitry to be placed alongside the interface.
What are the assembly advantages of the P-TR tape-and-reel format for the TSM-139-03-H-DV-P-TR in a high-volume SMT production environment?
The P-TR tape-and-reel format packages TSM-139-03-H-DV-P-TR connectors on continuous carrier tape compatible with standard SMT pick-and-place machines, enabling placement of thousands of parts per shift at typical rates exceeding 3,000 placements per hour. The sealed carrier also protects gold-plated contacts from oxidation and physical damage during storage and transport, preserving contact resistance below 20 mΩ per the SAMTEC specification.
