What are the key features of TSM-145-04-F-DV-P-TR?
- 90-position dual-row 0.100" (2.54 mm) pitch layout for maximum signal density in surface-mount designs
- Female (F) contact style with dual-voltage (DV) capability supporting 3.3 V and 5 V signal interfaces
- Polarization key (-P) prevents incorrect mating orientation, protecting circuits during assembly and field service
- Tape-and-reel (-TR) delivery compatible with automated SMT pick-and-place equipment for high-volume production
What is TSM-145-04-F-DV-P-TR used for?
The TSM-145-04-F-DV-P-TR is suited for high-density board-to-board and mezzanine interconnect in embedded computing platforms, industrial I/O expansion cards, and communications backplanes that require 90 signals across a single SMT interface. Female dual-row contacts at 0.100" pitch allow direct mating with standard TSM-series male headers, enabling modular stackable system architectures. The dual-voltage design accommodates mixed 3.3 V and 5 V logic planes in a single connector, reducing BOM complexity in multi-voltage embedded systems.

Frequently Asked Questions
How does the TSM-145-04-F-DV-P-TR compare to the TSM-144-04-FM-DV-P-TR for a 90-signal bus application?
The TSM-145-04-F-DV-P-TR provides 90 positions versus 88 on the -144 variant, adding 2 extra positions for power or ground returns. Both use 0.100" (2.54 mm) dual-row SMT pitch and share the dual-voltage (DV) polarized design, so routing the extra 2 pins can improve power distribution without changing the PCB footprint strategy or requiring a larger connector series.
For an industrial I/O expansion card with 45 digital channels per row, how does this connector support the layout?
The 90-position dual-row layout places 45 contacts per row at 0.100" (2.54 mm) pitch, spanning approximately 4.5" of board edge. Each row can carry 45 independent digital I/O channels at 3.3 V or 5 V, and the polarization key ensures the field technician cannot reverse the 90-pin interface during module hot-swap maintenance, preventing I/O channel assignment errors.
What soldering profile is compatible with the TSM-145-04-F-DV-P-TR for SMT reflow assembly?
As an SMT surface-mount terminal strip, the TSM-145-04-F-DV-P-TR is designed for standard lead-free reflow soldering with peak temperatures up to 260 °C per IPC/JEDEC J-STD-020 guidelines. The 90-position housing thermal mass requires a preheat ramp of approximately 2-3 °C/s to avoid thermal shock to the dual-row contact array during production line reflow.
How does tape-and-reel packaging affect procurement planning for the TSM-145-04-F-DV-P-TR?
Tape-and-reel quantities for the TSM-145-04-F-DV-P-TR typically range from 250 to 1,000 pieces per reel, aligning with standard SMT feeder formats. This eliminates cut-tape premiums on orders above 250 pieces and allows just-in-time kanban replenishment at roughly 2-week factory lead times, helping production planners maintain safety stock for runs of 500 to 5,000 boards.
