What are the key features of TSM-120-03-TM-DH-A-K-TR?
- 40 dual-row positions at 0.100" (2.54 mm) pitch providing 40 total contacts in an industry-standard SMT footprint
- Tape-and-reel (TR) packaging enabling high-speed automated pick-and-place assembly for volume production
- Surface-mount termination compatible with standard lead-free reflow profiles up to 260°C for RoHS-compliant manufacturing
What is TSM-120-03-TM-DH-A-K-TR used for?
TSM-120-03-TM-DH-A-K-TR is designed for high-density SMT board-to-board signal connections in embedded systems, industrial control modules, and development boards where 40 positions in a 0.100" pitch standard footprint are required. The tape-and-reel format supports automated assembly at throughputs exceeding 10,000 placements per hour, reducing per-unit assembly costs in volume production. Its dual-row configuration allows connecting 40 signal lines within the compact body length of a 2.54 mm pitch 20-position connector, ideal for SBC expansions and FPGA prototyping platforms.

Frequently Asked Questions
How many positions and what pitch does TSM-120-03-TM-DH-A-K-TR provide for SMT board connections?
TSM-120-03-TM-DH-A-K-TR provides 40 total positions in a dual-row layout at the industry-standard 0.100" (2.54 mm) pitch. The body spans approximately 50.8 mm in length and is suited for signal routing on embedded controller boards, breakout modules, and development platforms requiring up to 40 I/O lines.
What are the assembly advantages of TSM-120-03-TM-DH-A-K-TR in tape-and-reel format?
The TR (tape-and-reel) packaging of TSM-120-03-TM-DH-A-K-TR enables direct use with automated pick-and-place equipment, supporting placement rates above 10,000 parts per hour. This eliminates hand-loading costs for volume PCB assembly lines producing 500 or more boards per batch in industrial and consumer electronics manufacturing.
In which embedded system designs does the 0.100" pitch of TSM-120-03-TM-DH-A-K-TR offer routing advantages over 0.050" pitch connectors?
At 0.100" (2.54 mm) pitch, TSM-120-03-TM-DH-A-K-TR uses the universal spacing compatible with breadboards, standard IDC cables, and 2.54 mm mating headers. This simplifies prototyping and field-wiring in industrial PLC expansion modules and test fixture boards, where 0.050" pitch connectors require specialized tooling and increase misalignment risk during manual cable attachment.
Can TSM-120-03-TM-DH-A-K-TR be used in high-cycle mating applications for test and measurement fixtures?
TSM-120-03-TM-DH-A-K-TR is an SMT terminal strip designed primarily for board-to-board permanent or semi-permanent connections rather than high-cycle test socket use. For fixture applications requiring 500 or more mate/unmate cycles, consider SAMTEC's spring-contact or precision-machined alternatives rated for 1,000+ cycles; however, TSM-120 performs reliably for up to 100 cycles in low-frequency production test jigs with 40 signals at signal currents up to 1 A per pin.
