Frequently Asked Questions
How many positions and what pitch does the TSM-118-04-STL-DH-A-K-TR offer?
The TSM-118-04-STL-DH-A-K-TR provides 36 positions in a dual-row (2x18) arrangement on a 2.54 mm (.100") pitch, enabling compact high-density board-to-board signal connections in embedded and industrial PCB designs.
What does the STL suffix mean in the TSM-118-04-STL-DH-A-K-TR part number?
The STL suffix indicates solderable tail contacts, meaning the connector features through-hole pins that can be wave-soldered or hand-soldered to the PCB. This provides additional mechanical retention beyond standard SMT pads, especially important for connectors subjected to mating forces or vibration in a 36-pin, 2.54 mm pitch design.
In which assembly environments is the tape-and-reel packaging of this connector most beneficial?
Tape-and-reel (TR) packaging is most beneficial in high-volume automated SMT production lines using pick-and-place machines. For a 36-position dual-row connector like the TSM-118-04-STL-DH-A-K-TR with 2.54 mm pitch, reel packaging minimizes manual handling and ensures consistent placement accuracy across thousands of boards.
How does the TSM-118-04-STL-DH-A-K-TR compare to a single-row 18-pin strip for the same signal count?
A dual-row (2x18) configuration like the TSM-118-04-STL-DH-A-K-TR uses approximately half the board edge length compared to a single-row 18+18 arrangement. This saves board real estate while maintaining 2.54 mm pitch spacing between adjacent pins, which is critical for dense PCB layouts in space-constrained embedded systems.
