What are the key features of TSM-110-03-TM-DH-A-K-TR?
- 20-position dual-row terminal strip at 0.100" (2.54 mm) pitch with 10 contacts per row in a compact SMT footprint of approximately 25.4 mm
- Gold-plated contacts for contact resistance below 20 mΩ and stable performance across hundreds of mating cycles
- Tape-and-reel (TR) packaging enabling continuous automated SMT pick-and-place assembly at high production volumes
- Surface-mount termination compatible with lead-free reflow soldering at peak temperatures up to 260°C
What is TSM-110-03-TM-DH-A-K-TR used for?
The TSM-110-03-TM-DH-A-K-TR is widely used in embedded processor module interfaces, industrial I/O expansion boards, and compact test-and-measurement equipment where 20 positions provide sufficient capacity for mixed data, control, and power signals on a single connector. The 0.100" (2.54 mm) pitch maintains compatibility with a broad range of standard mating plugs and ribbon cable IDC connectors available from multiple suppliers. Tape-and-reel packaging makes this terminal strip directly compatible with automated SMT production lines, supporting efficient placement in medium to high-volume manufacturing environments.

Frequently Asked Questions
What is the position count, row configuration, and pitch of the TSM-110-03-TM-DH-A-K-TR?
The TSM-110-03-TM-DH-A-K-TR is a 20-position dual-row terminal strip with 10 contacts per row at 0.100" (2.54 mm) pitch. The overall connector body length is approximately 25.4 mm, fitting within a standard dual-row 0.100" grid footprint that is compatible with a wide range of IDC cable assemblies and mating plugs.
Which current capacity per pin does the TSM-110-03-TM-DH-A-K-TR support, and how does that affect power routing?
SAMTEC TSM series terminal strips are typically rated at 3 A per contact at room temperature, allowing engineers to dedicate multiple pins among the 20 total positions to power and ground rails. For a 3 A supply rail with 2x redundancy, only 2 pins are needed, leaving 18 of the 20 positions available for signal routing in a compact 25.4 mm body length.
How does the TSM-110-03-TM-DH-A-K-TR fit into an automated SMT production workflow?
The -TR designation means the component is packaged on tape-and-reel, typically on 13-inch reels holding 250 to 1000 units. This format integrates directly with standard pick-and-place machines, maintaining consistent part orientation across all 20 contact positions during SMT reflow cycles at up to 260°C without the manual intervention required for tube or bulk packaging.
What alternative connector pitch should designers consider when board height clearance is more critical than contact density for a 20-position interface?
When vertical clearance above the PCB is the primary constraint rather than pin density, designers may consider low-profile 0.100" (2.54 mm) pitch strip variants with a mounted height below 3 mm. However, if pin density is the constraint and layout space is limited to under 15 mm in connector length, stepping down to a 0.050" pitch connector with the same 20 positions would reduce body length by approximately 50%, from 25.4 mm to 12.7 mm.
