Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

Can I use TMM-120-05-T-S-SM in a board-to-board design with no guide hardware, or does it need alignment features?
TMM-120-05-T-S-SM is an unshrouded 2.00 mm surface-mount header, so it depends on the board layout and the mating connector’s tolerance for alignment. In board-to-board applications, add registration features, sufficient pad symmetry, and controlled coplanarity if the assembly must survive repeated mating without skew. For designs with manual mating, a shrouded mate or mechanical guides usually reduces pin stress and insertion error.
Is TMM-120-05-T-S-SM suitable for replacing a through-hole 2.00 mm header in an existing product?
TMM-120-05-T-S-SM can replace a through-hole header only if the PCB assembly can support surface-mount attachment and the mechanical load is low enough for SMT solder joints. Check board thickness, connector retention forces, and any cable or daughtercard leverage during handling. If the original design relied on the header as a structural anchor, the SMT version may need additional support or a different footprint strategy.
What should I check when matching a mating connector to TMM-120-05-T-S-SM?
TMM-120-05-T-S-SM is a 20-position, single-row, 2.00 mm pitch male header, so the mate must match pitch, row count, and contact geometry. Also confirm the mating contact wipe length and stack-up, since the 1.65 mm mating contact length affects engagement depth and tolerance to PCB-to-PCB variation. If the application sees vibration or repeated service cycles, verify the mate’s retention and contact normal force in the final stack.
Can TMM-120-05-T-S-SM handle industrial temperature ranges and long-term field operation?
TMM-120-05-T-S-SM is specified for -55°C to 105°C, which fits many industrial environments, but the full system should still be checked for thermal cycling, PCB CTE mismatch, and solder joint fatigue. Because it uses tin-plated contacts, the end application should also consider storage conditions and contact environment to avoid oxidation-related interface changes. For long-life equipment, validate the connector in the actual enclosure and load profile rather than relying only on the temperature range.
Is TMM-120-05-T-S-SM appropriate for power connections, or is it better for signals?
TMM-120-05-T-S-SM is rated at 3.2 A per contact, so it can be used for modest power distribution when the current is distributed across multiple pins and the thermal rise is acceptable. For higher inrush loads, sustained elevated ambient temperatures, or compact enclosures with limited airflow, derating is prudent. In mixed-signal designs, many engineers reserve this class of connector for signal and low-to-moderate power rather than main power entry.
What PCB layout details matter most for soldering TMM-120-05-T-S-SM reliably?
TMM-120-05-T-S-SM is a surface-mount header, so pad geometry, solder paste volume, and planarity matter more than with through-hole parts. Keep the footprint consistent with the mating connector’s coplanarity expectations and avoid uneven copper balance that can tilt the part during reflow. If the connector will see side loads, use the PCB land pattern and mechanical supports to keep solder joints from acting as the only structural element.
Can TMM-120-05-T-S-SM be used in a cable-to-board harness instead of board-to-board stacking?
TMM-120-05-T-S-SM is listed for board-to-board or cable style use, but the harness side should be chosen carefully because the connector is unshrouded and push-pull retained. For cable applications, confirm that the mating receptacle and cable assembly control strain relief and insertion direction. If the cable is frequently disconnected, the connector’s exposed male pins may be less forgiving than a keyed or shrouded alternative.
How does the tin contact finish on TMM-120-05-T-S-SM affect replacement decisions?
TMM-120-05-T-S-SM uses tin on the mating and post contact surfaces, which is common in cost-sensitive interconnects and works well when the mating environment is controlled. For low-level signals, contact maintenance depends on insertion cycle conditions, contamination control, and the mate’s wiping action. When comparing replacements, a gold-plated alternative may be preferred if the system faces intermittent signals, very low current, or harsher environmental exposure.
What are practical alternatives if I need a similar 2.00 mm Samtec header but different retention or stack height behavior?
For TMM-120-05-T-S-SM replacements, keep the focus on the TMM family and compare the exact suffix options rather than assuming a direct drop-in. Differences in mounting style, post length, shrouding, or mating height can change the enclosure fit and the final contact engagement. A substitute part may be electrically similar but still require a new footprint check, especially if the mechanical stack or access path is tight.
Is TMM-120-05-T-S-SM a good choice for vibration-prone equipment?
TMM-120-05-T-S-SM can work in vibration-sensitive assemblies if the PCB support, mating connector retention, and cable strain relief are designed around the connector’s push-pull behavior. Because it is an unshrouded header, side loading and micro-motion should be evaluated with the final enclosure and mounting scheme. In systems with frequent shock or vibration, engineers often validate contact continuity and solder joint integrity under test conditions before committing to production.
