What are the key features of TSM-135-03-SM-DH-A-P-TR?
- 70-position dual-row terminal strip on 0.100 inch (2.54 mm) pitch, supporting high pin-count signal connections in a single surface-mount component
- Dual-height (DH) profile accommodates mating connectors with clearance for components beneath the mating pair, increasing PCB layout flexibility
- Surface-mount (SM) termination compatible with automated SMT reflow assembly for consistent solder joint quality across high-volume production runs
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly with zero manual handling, improving throughput and reducing placement errors
What is TSM-135-03-SM-DH-A-P-TR used for?
The TSM-135-03-SM-DH-A-P-TR is used in industrial control backplanes, modular embedded computing boards, and test fixture systems where a high pin-count 70-position 0.100 inch pitch surface-mount strip simplifies dense multi-signal interconnect. Its dual-height form factor enables stacked PCB assemblies where vertical clearance between the two boards must accommodate components mounted on the lower board surface. Tape-and-reel packaging makes this connector suited for automated high-volume PCB manufacturing in telecommunications and data center hardware.

Frequently Asked Questions
How many positions does the TSM-135-03-SM-DH-A-P-TR have and what is its contact pitch?
The TSM-135-03-SM-DH-A-P-TR has 70 positions arranged in a dual-row configuration at 0.100 inch (2.54 mm) pitch, offering a high pin-count interconnect option in a well-standardized footprint that is widely supported by connector housings and IDC cable assemblies.
What does the dual-height (DH) designation mean for PCB stacking in TSM-135-03-SM-DH-A-P-TR?
The dual-height profile provides increased standoff distance between mated boards, typically several millimeters more than a standard-height TSM, creating clearance for SMT components mounted on the board surface beneath the connector pair. This is valuable in modular designs where 70 signals must pass between two tightly stacked PCBs without component interference.
Is the TSM-135-03-SM-DH-A-P-TR suitable for high-volume automated PCB assembly?
Yes. The TR suffix confirms tape-and-reel packaging, enabling automated pick-and-place machines to place the 70-position connector at standard SMT line speeds, while the SM termination is compatible with lead-free reflow soldering at up to 260°C peak, supporting high-throughput manufacturing for telecommunications and industrial electronics.
In which scenarios would a designer choose TSM-135-03-SM-DH-A-P-TR over a through-hole 70-position strip?
Surface-mount termination is preferred when single-sided PCB assembly is required, when board thickness or via drill restrictions make through-hole impractical, or when automated reflow soldering replaces wave soldering. The 0.100 inch pitch surface-mount strip also offers better coplanarity control across the 70 positions, reducing soldering defects at scale compared to through-hole alternatives.
