What are the key features of TFC-110-32-L-D-A-K-TR?
- 1.27 mm fine-pitch dual-row layout in a compact 0.625 x 0.441 inch body for high-density SMT board-to-board connections
- 15 microinch gold mating contact finish provides a contact resistance below 15 milliohms and excellent corrosion resistance
- Key polarization (K) prevents incorrect mating orientation, critical for fine-pitch connectors with 20 positions
- Peg board mounting (PEG) mechanically locks the connector body to the PCB before reflow soldering at up to 260 degrees C
What is TFC-110-32-L-D-A-K-TR used for?
TFC-110-32-L-D-A-K-TR is designed for compact board-to-board mating in FPGA evaluation modules, high-speed data acquisition cards, and embedded computing daughterboards where a 20-position dual-row connector must fit within a 0.625 inch body length. Its 1.27 mm pitch halves the footprint compared to 2.54 mm pitch alternatives, making it ideal for rack-mounted server blades and industrial control modules requiring high channel density. The tape-and-reel packaging and SMT form factor support automated high-volume assembly with minimal manual soldering.

Frequently Asked Questions
How does TFC-110-32-L-D-A-K-TR's peg mounting aid solder joint quality during PCB reflow?
TFC-110-32-L-D-A-K-TR includes a peg (PEG) board mounting feature consisting of plastic retention pegs that snap into holes in the PCB and physically hold all 20 positions of the fine-pitch 1.27 mm connector in precise alignment during SMT reflow at temperatures up to 260 degrees C. This prevents the lightweight connector body from floating or shifting on solder paste before the joints solidify, reducing the risk of tombstoning or solder bridging between the closely spaced 1.27 mm pitch pads.
What gold plating thickness does TFC-110-32-L-D-A-K-TR have on its mating contacts, and how does this compare to standard flash gold?
TFC-110-32-L-D-A-K-TR uses 15 microinches of gold on its mating contacts, which is significantly thicker than flash gold (typically 2 to 4 microinches). This heavier gold plating provides a contact resistance below 15 milliohms across all 20 positions and supports at least 100 mate-unmate cycles before measurable wear. Thicker gold is preferred in applications such as removable test daughtercards or reconfigurable I/O modules where frequent connector cycling is expected over the product's service life.
For a 20-pin interface on a high-speed acquisition card, how does TFC-110-32-L-D-A-K-TR reduce PCB layout area compared to a 2.54 mm pitch alternative?
TFC-110-32-L-D-A-K-TR operates on a 1.27 mm pitch, giving a body length of only 0.625 inch for 20 positions. An equivalent 20-position connector at the standard 2.54 mm pitch would require approximately 1.25 inch of body length, meaning TFC-110-32-L-D-A-K-TR saves about 0.625 inch or 50 percent in the pitch dimension. Combined with a body breadth of only 0.225 inch, this enables the 20-pin interface to fit within a board area of less than 0.15 square inch, freeing routing space on dense acquisition card PCBs.
Is TFC-110-32-L-D-A-K-TR available in tape-and-reel packaging, and how does this support automated assembly?
Yes, TFC-110-32-L-D-A-K-TR ships in tape-and-reel (TR) format, which is directly compatible with standard SMT pick-and-place machines operating at placement speeds exceeding 10,000 components per hour. Tape-and-reel packaging protects the 1.27 mm fine-pitch connector contacts during transit and storage, reducing handling damage rates. For production runs with thousands of boards per shift, TR packaging eliminates manual loading and ensures consistent component orientation, which is especially important for polarized (K) connectors like this model.
