Frequently Asked Questions
What pin count and pitch does the TSM-125-03-TM-DH-A-K-TR provide for board interconnect designs?
The TSM-125-03-TM-DH-A-K-TR provides 50 positions in a dual-row layout on a 2.54 mm (0.100 inch) pitch, giving designers 2 rows of 25 pins in a standard SMT footprint compatible with widely available 0.100 inch dual-row land patterns.
How does surface mount termination on the TSM-125-03-TM-DH-A-K-TR affect the PCB stack-up compared to a through-hole 50-pin strip?
The SMT termination eliminates through-hole drilling on all 50 pins, reducing PCB manufacturing cost and preserving inner layer routing channels. This is especially useful on 4-layer or 6-layer boards where each drilled via would otherwise consume routing space and require a 0.3 mm to 0.4 mm annular ring clearance.
Which embedded computing and industrial applications benefit from using TSM-125-03-TM-DH-A-K-TR as a board-edge strip?
Backplane interconnects, FPGA daughtercards, industrial motion controller boards, and data acquisition modules that need 50 signals routed at 2.54 mm pitch and operate over -40°C to +85°C are well served by this surface mount terminal strip in tape-and-reel format.
