What are the key features of TFC-145-02-L-D?
- 90-position dual-row layout at 0.050 inch pitch enables high-density board stacking in compact PCB footprints
- Gold (10 microinch) mating contact finish with phosphor bronze base material ensures low-contact-resistance connections over thousands of mating cycles
- Shrouded housing provides mechanical keying and prevents mis-mating during board assembly and field service
- Tin-over-nickel termination finish on PCB tails offers solderability and corrosion resistance for standard wave or reflow processes
What is TFC-145-02-L-D used for?
TFC-145-02-L-D is used in board-to-board stacking applications within industrial embedded systems, test and measurement instrumentation, and high-density backplane interconnect designs where 0.050 inch pitch and 90 positions satisfy dense signal routing requirements. The gold-plated contacts and shrouded housing make it suitable for mezzanine modules, daughtercard assemblies, and stackable SBC expansion boards. It also serves communication equipment racks where reliable, low-profile connectors must handle repeated mate-demate cycles.

Frequently Asked Questions
How many positions and what pitch does TFC-145-02-L-D use for board stacking?
TFC-145-02-L-D provides 90 positions arranged in a dual-row layout at 0.050 inch (1.27 mm) pitch, allowing high-density interconnect between stacked boards while keeping the connector footprint compact enough for tight PCB real estate in mezzanine and backplane designs.
What contact materials and finish does TFC-145-02-L-D use to ensure reliable signal integrity?
The connector uses phosphor bronze contacts with a gold (10 microinch) finish on the mating surfaces and a tin-over-nickel barrier finish on the PCB termination tails, delivering low contact resistance typically below 20 milliohms while resisting oxidation across the operating temperature range of -55°C to +125°C.
For which compact interconnect scenarios is TFC-145-02-L-D preferred over a standard 0.100 inch pitch terminal strip?
When PCB area is constrained and signal count exceeds 50, the 0.050 inch pitch of TFC-145-02-L-D delivers twice the contact density of a 0.100 inch (2.54 mm) strip in the same board length, making it the preferred choice for mezzanine modules, SBC expansions, and instrument front-end boards where routing 90 signals at 0.100 inch pitch would exceed available connector space.
Does the shrouded housing on TFC-145-02-L-D prevent mis-insertion errors during assembly?
Yes, the shrouded housing mechanically guides the mating connector and enforces a single correct insertion orientation, preventing the 180-degree mis-mating errors common with unshrouded 0.050 inch strips; this reduces rework rates and protects the 90 signal pins from bending forces during manual or automated board assembly.
