Frequently Asked Questions
What is the contact pitch and row count of the TSM-129-01-G-SH-A terminal strip?
The TSM-129-01-G-SH-A features a 0.100-inch (2.54 mm) contact pitch in a dual-row configuration with 29 positions total, providing high-density connectivity in a compact surface mount footprint suitable for space-constrained PCB designs.
How does the gold plating on TSM-129-01-G-SH-A contacts benefit signal integrity in low-voltage applications?
Gold-plated contacts provide extremely low contact resistance, typically below 20 milliohms, which is critical for low-voltage signals under 3.3 V or 5 V where voltage drop must be minimized. Gold also resists oxidation, ensuring reliable mating even after hundreds of insertion cycles in industrial environments.
Which PCB assembly processes are compatible with the TSM-129-01-G-SH-A surface mount terminal strip?
The TSM-129-01-G-SH-A is designed for standard SMT reflow soldering processes with a peak reflow temperature up to 260°C, compatible with SAC305 and other lead-free solder alloys. Its surface mount pads support automated pick-and-place assembly, reducing hand-soldering labor in high-volume production runs.
When should engineers choose the shielded TSM-129-01-G-SH-A over an unshielded variant for their designs?
The shielded housing (SH suffix) of TSM-129-01-G-SH-A should be selected when operating in environments with EMI levels above 30 dBµV/m or when signals below 100 mV are present, such as in sensor interfaces or RF-adjacent circuits where unshielded connectors could introduce crosstalk exceeding system noise budgets.
