Key Features
- 44-position single-row dual-high terminal strip at 0.100" (2.54 mm) pitch provides high contact density for versatile board-to-board applications
- Dual-high (DH) profile creates inter-board clearance suitable for stacked-board designs with components on mating board surfaces
- Tape-and-reel (TR) packaging enables direct use with automated pick-and-place SMT assembly equipment for high-volume production
- Wide 0.100" pitch maintains compatibility with standard 2.54 mm pitch mating connectors and prototyping tools
Applications
The TSM-122-01-TM-DH-A-K-TR serves as a primary board header in FPGA evaluation boards, industrial I/O expansion cards, and embedded computer modules requiring 44 positions at 0.100" pitch. Its dual-high profile accommodates board-to-board stacking with component clearance, making it widely used in backplane architectures, laboratory prototype boards, and modular signal distribution systems.

Frequently Asked Questions
How does the TSM-122-01-TM-DH-A-K-TR dual-high profile affect inter-board spacing in stacked assemblies?
The dual-high (DH) profile of the TSM-122-01-TM-DH-A-K-TR extends the connector's standing height above a standard single-height 0.100" (2.54 mm) pitch terminal strip, providing additional clearance between the two mated boards. This prevents mechanical collision with surface mount components on the underside of the upper board in stacked-board and mezzanine assemblies spanning all 44 positions.
What signal types can be distributed across the 44 positions of the TSM-122-01-TM-DH-A-K-TR?
With 44 positions at 0.100" (2.54 mm) pitch, the TSM-122-01-TM-DH-A-K-TR can simultaneously route general-purpose I/O lines, power supply rails, SPI, I2C, and UART communication signals, plus analog reference voltages. This broad signal capacity makes it practical for FPGA expansion headers, multi-function I/O backplanes, and development platforms needing many parallel connections in a single 2.54 mm pitch connector.
When is the TSM-122-01-TM-DH-A-K-TR preferred over a lower position-count 0.100" pitch terminal strip?
Designers should select the TSM-122-01-TM-DH-A-K-TR when more than 36 positions are needed in a single 0.100" pitch header, avoiding the use of two separate connectors. Consolidating 44 signals into one strip reduces board area, simplifies routing, and avoids misalignment issues that arise when multiple shorter strips are placed adjacent to each other on the PCB.
How does tape-and-reel packaging benefit high-volume production of boards using the TSM-122-01-TM-DH-A-K-TR?
Tape-and-reel (TR) packaging feeds the TSM-122-01-TM-DH-A-K-TR directly into automated pick-and-place machines, enabling consistent, uninterrupted placement of all 44-position terminal strips at 0.100" pitch. This eliminates manual handling, maintains correct connector orientation, and supports continuous SMT production runs without pausing for component tray replenishment.
