What are the key features of SMH-133-02-SM-S-TR?
- 33-position single-row layout at 0.100-inch (2.54 mm) pitch provides broad compatibility with standard 2.54 mm male pin headers
- Horizontal surface-mount orientation minimizes assembly height for low-profile enclosures and panel-mount applications
- Gold-plated contact finish ensures contact resistance below 20 mΩ and long mating durability for field-serviceable modules
- Tape-and-reel form factor enables automated SMT assembly in high-volume manufacturing without manual connector loading
What is SMH-133-02-SM-S-TR used for?
The SMH-133-02-SM-S-TR is used in modular embedded systems, industrial control boards, and prototype expansion platforms that require a horizontal 0.100-inch pitch socket accepting standard headers. It is also suited for backplane-to-daughtercard interconnection in communication equipment and test fixtures where a 33-position single-row low-profile mating interface is needed.

Frequently Asked Questions
How does the 33-position count of the SMH-133-02-SM-S-TR compare to similar SAMTEC SMH series variants for signal bus routing?
With 33 positions at 0.100-inch (2.54 mm) pitch, the SMH-133-02-SM-S-TR spans approximately 81 mm in length along the row, enabling routing of up to 33 individual signals including power, ground, and control lines. Engineers needing fewer signals can choose SMH-129 (29 positions) or SMH-125 (25 positions) from the same series to reduce connector footprint.
What are the soldering process requirements for mounting the SMH-133-02-SM-S-TR in a reflow assembly line?
The SMH-133-02-SM-S-TR is designed for SMT reflow soldering with a peak temperature tolerance of 260°C per IPC/JEDEC J-STD-020, matching standard lead-free reflow profiles. Solder paste must be applied at 2.54 mm pitch without bridging, and the horizontal body orientation requires adequate clearance of at least 5 mm beside the mating opening to prevent neighboring components from blocking header insertion.
Which alternative SAMTEC connector should be considered when a vertical rather than horizontal socket orientation is needed for the same 33-position 0.100-inch pitch interface?
For a vertical surface-mount orientation with the same 33-position 0.100-inch pitch footprint, engineers can evaluate the SAMTEC SSW series (vertical SMT socket strips) or the SFM series. Switching to vertical orientation changes the mating direction from horizontal to perpendicular to the PCB, increasing clearance requirements above the board by approximately 8 mm to 12 mm depending on the mated header height.
