Frequently Asked Questions
How many positions does the TSM-147-03-LM-DV-P-TR provide and how are they arranged?
The TSM-147-03-LM-DV-P-TR provides 94 positions arranged in a dual-row configuration on a 2.54 mm pitch, giving 47 contacts per row. This layout reduces the required PCB edge length by half compared to a single-row strip of the same count, making it suitable for compact industrial backplane and daughter-card designs where board real estate is limited.
What soldering process is compatible with the TSM-147-03-LM-DV-P-TR and what peak reflow temperature does it withstand?
The TSM-147-03-LM-DV-P-TR is designed for surface-mount reflow soldering and is rated to withstand a peak reflow temperature of 260°C, in line with JEDEC J-STD-020 MSL requirements. This allows it to pass through standard lead-free reflow ovens without connector damage, simplifying assembly integration alongside other SMT components on the same board.
In which application areas is the TSM-147-03-LM-DV-P-TR commonly deployed?
The TSM-147-03-LM-DV-P-TR is commonly found in FPGA development boards, industrial I/O expansion cards, test and measurement instruments, and embedded computing carrier modules where 94 signals must be routed across a board-to-board interface at 2.54 mm pitch. Its gold-plated contacts with contact resistance below 20 mΩ ensure consistent signal quality in high-cycle-count mating environments.
What packaging format does the TSM-147-03-LM-DV-P-TR come in and how does it affect procurement for volume production?
The TSM-147-03-LM-DV-P-TR is supplied in tape-and-reel format, indicated by the -TR suffix, enabling automated pick-and-place loading at standard feeder pitches used in SMT assembly lines. Tape-and-reel packaging reduces handling errors, supports continuous-feed machines, and is the preferred format when ordering quantities of 500 or more units for volume PCB production.
What contact plating does the TSM-147-03-LM-DV-P-TR use and what mating cycle life does this support?
The TSM-147-03-LM-DV-P-TR uses gold-plated contacts with a finish that sustains a mating cycle life of at least 30 cycles while maintaining contact resistance below 20 mΩ. Gold plating resists oxidation and fretting corrosion, making these connectors suitable for removable daughter cards and test fixtures that are inserted and removed repeatedly over the product lifetime.
