What are the key features of TSM-123-02-FM-DH-A-K-TR?
- 46-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch with FM (flush mount) termination style, enabling low-profile solder attachment on standard 2.54 mm grid PCBs
- Dual-row DH (dual height) configuration providing 23 contacts per row for high pin-count signal or power distribution across a compact SMT footprint
- Tape-and-reel (TR) packaging for automated pick-and-place assembly, supporting high-volume PCB production with consistent component orientation and placement accuracy
What is TSM-123-02-FM-DH-A-K-TR used for?
The TSM-123-02-FM-DH-A-K-TR suits high-density board-to-board signal distribution in embedded system backplanes, industrial controller expansion boards, and evaluation kit connectors requiring 46 pins at the standard 2.54 mm pitch. The flush mount termination style keeps the connector profile low on the PCB surface, benefiting designs with strict height clearance requirements in enclosed enclosures. Tape-and-reel packaging makes it compatible with automated SMT assembly lines at production scale.

Frequently Asked Questions
How does the FM (flush mount) termination style of the TSM-123-02-FM-DH-A-K-TR affect its PCB mounting profile compared to standard SMT terminal strips?
The FM (flush mount) termination style of the TSM-123-02-FM-DH-A-K-TR keeps the connector leads flush against the PCB surface during reflow soldering at temperatures up to 260°C, resulting in a lower overall board profile compared to gull-wing or elevated foot termination styles. This is beneficial in enclosures with tight height clearances for 46-pin dual-row SMT connectors at 2.54 mm pitch.
What does the TR suffix signify for the TSM-123-02-FM-DH-A-K-TR, and how does it impact procurement for high-volume orders?
The TR suffix indicates tape-and-reel packaging, meaning the TSM-123-02-FM-DH-A-K-TR is supplied on a continuous reel suitable for automated pick-and-place SMT assembly equipment. For high-volume PCB production orders, tape-and-reel packaging reduces manual handling, maintains correct component orientation, and is compatible with standard IEC 60286-3 reel dimensions used in most SMT lines handling 2.54 mm pitch connectors.
When would an engineer choose the TSM-123-02-FM-DH-A-K-TR over the STL variant (TSM-123-02-STL-DH-A-K-TR) for the same 46-pin application?
An engineer would choose the TSM-123-02-FM-DH-A-K-TR over the STL variant when the design requires a flush mount (FM) termination profile rather than a standard lead (STL) style, typically to achieve a lower solder joint height and more uniform PCB surface for 46-pin dual-row 2.54 mm applications. The FM style also provides a more defined coplanarity specification for reflow soldering of the 46 dual-row contacts, which benefits tightly tolerance automated SMT assembly processes.
