What are the key features of TSM-135-03-STL-DH-A-K-TR?
- 70 positions in a dual-row 0.100" (2.54 mm) pitch layout for high pin-count signal routing
- Stand-off lead (STL) style provides additional clearance beneath the connector body for solder joint inspection and cleaning
- Surface mount termination compatible with automated SMT reflow assembly
- Tape-and-reel (TR) packaging supports high-volume pick-and-place production
- Gold-plated contacts deliver consistent low-resistance mating performance over many cycles
What is TSM-135-03-STL-DH-A-K-TR used for?
TSM-135-03-STL-DH-A-K-TR is suited for industrial automation, embedded computing, and test and measurement platforms requiring high-density board-to-board connections with enhanced solder joint accessibility. The stand-off lead style makes it particularly valuable in designs where post-assembly inspection or cleaning under the connector body is a manufacturing requirement.

Frequently Asked Questions
What distinguishes the STL lead style of TSM-135-03-STL-DH-A-K-TR from a standard surface mount terminal strip?
The STL (stand-off lead) style on TSM-135-03-STL-DH-A-K-TR elevates the connector body above the PCB surface, providing clearance typically around 0.030" to 0.060" beneath the housing. This gap allows flux cleaning and optical inspection of the 70 solder joints without removing the connector.
How many signal connections does TSM-135-03-STL-DH-A-K-TR accommodate, and how are they arranged?
TSM-135-03-STL-DH-A-K-TR accommodates 70 signal positions arranged in 2 rows at a 0.100" (2.54 mm) pitch. The dual-row layout enables high pin-count interconnects while limiting the connector's board length to approximately 3.5 inches for the 35-position-per-row arrangement.
For industrial PCB designs requiring post-solder cleaning, how does TSM-135-03-STL-DH-A-K-TR support that process?
The stand-off lead geometry of TSM-135-03-STL-DH-A-K-TR creates clearance under the 70-pin connector body, allowing aqueous or solvent cleaning agents to flow beneath the housing and remove flux residue from all solder joints during in-line cleaning operations common in industrial-grade PCB manufacturing.
What tape-and-reel quantity and packaging format applies to TSM-135-03-STL-DH-A-K-TR for production procurement?
TSM-135-03-STL-DH-A-K-TR is supplied in tape-and-reel (TR) format, compatible with standard 8 mm or larger carrier tape for automated pick-and-place equipment. Buyers should confirm reel quantities with SAMTEC distributors, as reel sizes for 70-position dual-row connectors typically run in quantities of 100 to 500 pieces per reel.
