Key Features
- 25-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch with horizontal tail orientation for low-profile board-to-board or board-to-cable connections
- Shielded (SH) metal housing provides grounded EMI shielding around all 50 contacts, reducing radiated emissions in noise-sensitive RF and mixed-signal designs
- Surface-mount termination supports automated reflow soldering assembly and eliminates through-hole drilling for denser double-sided PCB layouts
Applications
The TSM-125-02-H-SH-A is designed for mixed-signal PCBs, wireless communication modules, and industrial control equipment where a 25-position dual-row SMT header with integrated EMI shielding is required. Its horizontal tail configuration and shielded housing make it well suited for panel-edge connector positions and RF-adjacent board regions where unshielded headers would contribute to conducted or radiated interference.

Frequently Asked Questions
How does the shielded housing of TSM-125-02-H-SH-A reduce EMI in a mixed-signal PCB design?
The SH (shielded) metal housing enclosure is connected to the PCB ground plane and surrounds all 50 contacts of the TSM-125-02-H-SH-A. This grounded shell attenuates both inbound and outbound electromagnetic interference, preventing high-frequency switching noise from digital signals from coupling into adjacent analog or RF circuitry operating on the same board in frequency bands above 100 MHz.
What is the total contact count of TSM-125-02-H-SH-A and how is it arranged?
The TSM-125-02-H-SH-A provides 50 total contacts arranged as 25 dual-row positions at a 0.100 inch (2.54 mm) pitch. The dual-row SMT configuration maximizes signal density per unit board length while keeping the connector body compact, suitable for mid-density interconnect needs in communication modules and embedded controllers.
In what scenario would TSM-125-02-H-SH-A be selected over TSM-125-02-H-A (without shield) for a wireless gateway PCB?
A wireless gateway PCB running both high-speed digital interfaces and sub-GHz or 2.4 GHz RF circuits would benefit from the TSM-125-02-H-SH-A. The metal shield prevents the 50 fast-switching connector signals from radiating into the RF front-end at frequencies where unshielded interconnects would degrade receiver sensitivity or cause spurious emissions exceeding FCC Part 15 or ETSI EN 300 220 radiated emission limits.
