What are the key features of TSM-122-01-SS-DH-A-K-TR?
- 44-position dual-row terminal strip on 0.100" (2.54 mm) pitch covers a broad range of signal routing needs on standard PCB grids
- Solder-slug (SS) termination provides a flat, wide contact pad for reliable solder joint formation and improved adhesion during reflow
- Gold-plated contacts maintain contact resistance below 20 milliohms across extended service life and multiple mating cycles
- Tape-and-reel (TR) packaging enables continuous automated pick-and-place assembly at high production volumes
What is TSM-122-01-SS-DH-A-K-TR used for?
The TSM-122-01-SS-DH-A-K-TR is used in industrial control backplanes, embedded system expansion boards, and test and measurement equipment that require 44 signal connections on a standard 2.54 mm pitch dual-row terminal strip. Its solder-slug termination ensures consistent solder joint quality during reflow in dense PCB assemblies with tightly spaced pads. The tape-and-reel format supports integration into automated SMT lines at high throughput volumes.

Frequently Asked Questions
What is the contact count and pitch of the TSM-122-01-SS-DH-A-K-TR?
The TSM-122-01-SS-DH-A-K-TR provides 44 contacts in a dual-row layout on a 0.100 inch (2.54 mm) pitch, making it a mid-to-high density surface mount terminal strip suited for industrial control boards and embedded systems needing 44 signal channels through a single reliable connector on a standard PCB grid.
What benefits does the solder-slug termination of TSM-122-01-SS-DH-A-K-TR offer during PCB assembly?
The solder-slug (SS) termination on TSM-122-01-SS-DH-A-K-TR provides a flat, wide solder contact surface that distributes solder paste more evenly across the 44-position pad footprint, reducing bridging and voiding risk during reflow and improving joint strength compared to standard round lead terminations in dense SMT assemblies.
How does TSM-122-01-SS-DH-A-K-TR support high-volume manufacturing workflows?
Packaged in tape-and-reel (TR) format, TSM-122-01-SS-DH-A-K-TR feeds directly into automated pick-and-place equipment at standard 8 mm or 12 mm tape widths, enabling placement of thousands of 44-pin connectors per hour with high accuracy and minimal manual intervention, reducing per-unit assembly cost in volume SMT production.
When would TSM-122-01-SS-DH-A-K-TR be selected over a 0.050 inch pitch connector for the same pin count?
The TSM-122-01-SS-DH-A-K-TR at 0.100 inch (2.54 mm) pitch is preferred over finer-pitch alternatives when connectors must mate with standard header pins on adjacent boards or backplanes, when wider solder pad spacing improves solder joint inspection reliability, or when lower-cost PCB fabrication with 2.54 mm grid routing is required for the 44-pin interface.
