What are the key features of TSM-145-01-TM-DV-P-TR?
- 90-position dual-row configuration on 0.100" (2.54 mm) standard pitch, providing high pin count in a compact surface mount footprint
- Dual-voltage (DV) and polarized (P) design prevents mis-mating and supports mixed-voltage bus architectures in backplane and motherboard applications
- Top-mount (TM) termination style and tape-and-reel packaging compatible with standard SMT pick-and-place equipment for automated high-volume assembly
What is TSM-145-01-TM-DV-P-TR used for?
The TSM-145-01-TM-DV-P-TR is suited for high-density backplane, motherboard, and industrial bus connections in embedded computing, telecommunications, and automation systems. Its 90-position count supports complex multi-signal routing including power distribution and high-speed data buses across a single connector. The polarization key and dual-voltage rating reduce assembly errors and support multi-rail power architectures common in 3.3 V, 5 V, and 12 V systems.

Frequently Asked Questions
What is the total contact count and row configuration of the TSM-145-01-TM-DV-P-TR?
The TSM-145-01-TM-DV-P-TR features 90 positions arranged in a dual-row layout with 45 contacts per row, on a 0.100-inch (2.54 mm) pitch. This configuration provides one of the highest pin counts in the TSM surface mount terminal strip family, suitable for complex multi-bus backplane interconnects.
How does the top-mount (TM) termination of the TSM-145-01-TM-DV-P-TR differ from standard mount variants?
Top-mount termination means the solder leads exit from the top surface of the connector body rather than the bottom, enabling PCB pad patterns that reduce trace routing conflicts under the connector. This is particularly useful on densely routed boards where 90-contact SMT footprints at 2.54 mm pitch must coexist with nearby via fields or power planes.
For which industrial systems is the TSM-145-01-TM-DV-P-TR's 90-position polarized design most beneficial?
Industrial automation backplanes, VME bus carrier cards, and multi-module PLCs benefit most from the 90-position polarized design. The polarization feature physically blocks incorrect mating across all 90 contacts, preventing damage to mixed-voltage rails such as 3.3 V logic and 24 V actuator power that may share the same connector body in field-installed industrial control racks.
What assembly advantages does tape-and-reel packaging provide for the TSM-145-01-TM-DV-P-TR in volume production?
Tape-and-reel packaging allows SMT pick-and-place machines to place the 90-position connector at throughputs exceeding 1000 units per hour, compared to manual tray-loaded assembly. For the 2.54 mm pitch SMT footprint, automated placement achieves consistent ±0.05 mm positional accuracy, reducing solder bridges and open joints across the 90-contact row during reflow at temperatures up to 260°C.
