Frequently Asked Questions
What does the dual-height (DH) designation mean for the TSM-118-03-S-DH-A-K-TR?
The dual-height (DH) designation indicates the connector body has an increased height compared to standard terminal strips. This extra clearance accommodates taller mating connector housings or PCB features adjacent to the mating interface. The additional body height also improves grip and retention force during mating and unmating cycles, beneficial in environments subject to vibration exceeding 5 G.
Which automated assembly requirements make the TSM-118-03-S-DH-A-K-TR's tape-and-reel format advantageous?
The tape-and-reel (TR) format of the TSM-118-03-S-DH-A-K-TR enables placement by standard SMT pick-and-place equipment at production rates of thousands of components per hour. It eliminates manual tube feeding or bulk-tray handling, reducing misfeeds and placement errors. This format is especially beneficial for high-volume orders of 1,000 units or more, where consistent placement of the 36 contacts must meet tight positional tolerances.
How many signal lines can the TSM-118-03-S-DH-A-K-TR support on a single board edge?
The TSM-118-03-S-DH-A-K-TR provides 36 positions in a single-row layout at 0.100-inch pitch, spanning approximately 3.5 inches along the board edge. This supports up to 36 single-ended signals or 18 differential pairs, making it suitable for parallel bus interfaces such as address or data buses in embedded processor boards.
Is the TSM-118-03-S-DH-A-K-TR compatible with lead-free assembly requirements?
Yes, the TSM-118-03-S-DH-A-K-TR is designed for surface-mount reflow soldering and is compatible with lead-free (RoHS-compliant) assembly processes up to 260°C peak reflow temperature. The connector body material withstands standard reflow profiles without deformation, and the contact plating is selected for compatibility with SAC305 and other lead-free solder alloys.
