What are the key features of TSM-128-03-FM-SH-A?
- 28-position dual-row SMT terminal strip with 2.54 mm (0.100 inch) pitch for standard grid PCB layouts
- Horizontal single-row orientation (SH-A suffix) simplifies low-profile surface mount assembly
- Shielded (SH) construction reduces EMI susceptibility in noise-sensitive signal routing applications
- Female (FM) socket contacts accept standard 0.100 inch header pins for versatile mating compatibility
- RoHS-compliant surface mount package supports automated pick-and-place and reflow soldering processes
What is TSM-128-03-FM-SH-A used for?
The TSM-128-03-FM-SH-A is suited for signal routing and interface expansion on PCBs requiring a shielded 28-position dual-row SMT connector with 2.54 mm pitch, such as embedded system backplanes and test fixture boards. Its horizontal single-row orientation enables low-profile board-to-board or wire-to-board interconnections in industrial instrumentation and communication modules. The shielded design makes it particularly valuable in applications where EMI mitigation is required alongside high pin-count connectivity.

Frequently Asked Questions
How many positions and what pitch does the TSM-128-03-FM-SH-A provide?
The TSM-128-03-FM-SH-A offers 28 positions arranged in a dual-row configuration with a 2.54 mm (0.100 inch) pitch. This standard pitch ensures compatibility with a wide range of mating headers and socketed PCB components in embedded system designs.
What does the shielded (SH) designation mean for signal integrity in the TSM-128-03-FM-SH-A?
The SH designation indicates a shielded construction that surrounds the contact area with a metallic enclosure, reducing EMI coupling by several decibels in high-frequency environments. This makes the connector suitable for sensor interface boards and communication modules where unshielded 2.54 mm connectors would introduce crosstalk above 100 MHz.
Can the TSM-128-03-FM-SH-A be used as a replacement for standard unshielded 28-position dual-row headers?
The TSM-128-03-FM-SH-A shares the same 2.54 mm pitch and 28-position dual-row footprint as unshielded equivalents, enabling drop-in PCB footprint compatibility. The added shield layer increases the body height slightly, so designers should verify 3 mm of additional vertical clearance before substituting it in space-constrained enclosures.
What soldering process is recommended for the TSM-128-03-FM-SH-A surface mount terminal strip?
As a surface mount component, the TSM-128-03-FM-SH-A is compatible with standard reflow soldering at peak temperatures up to 260°C, consistent with SAMTEC SMT connector guidelines. Paste stencil printing with 0.150 mm apertures across the 28 pads is recommended to achieve consistent solder joints during automated assembly.
