What are the key features of TFC-105-02-FM-D-A-K?
- 10-position dual-row layout at 0.050" (1.27 mm) pitch in a compact body 0.375 inch long for space-constrained PCB designs
- 3µ" gold mating contacts over phosphor bronze for low contact resistance and extended mating cycle reliability
- Keying feature and PEG mounting option prevent mis-mating and secure the connector mechanically during board assembly and use
What is TFC-105-02-FM-D-A-K used for?
The TFC-105-02-FM-D-A-K is well suited for compact embedded modules, sensor interface boards, and portable industrial devices requiring 10-position dual-row board-to-board connections at 0.050" pitch. Its small body dimensions of 0.375 inch length and 0.225 inch breadth minimize the PCB footprint while the gold-plated phosphor bronze contacts ensure signal integrity. The keyed design prevents incorrect mating in assemblies where multiple small connectors share the same board area.

Frequently Asked Questions
What contact material and finish does the TFC-105-02-FM-D-A-K use, and how does that affect performance?
The TFC-105-02-FM-D-A-K uses phosphor bronze contacts with 3µ" gold finish on the mating interface and matte tin (Sn) on the termination side. The 3µ" gold mating finish provides low and stable contact resistance over hundreds of mating cycles, making it reliable for board-to-board signal connections in industrial and embedded computing environments.
What are the key physical dimensions of the TFC-105-02-FM-D-A-K and how do they constrain PCB layout?
The TFC-105-02-FM-D-A-K has a body length of 0.375 inch, body breadth of 0.225 inch, and body depth of 0.226 inch. These compact dimensions allow it to be placed in very tight PCB areas while still providing 10 dual-row contact positions at 0.050" pitch, leaving space for nearby components such as decoupling capacitors or signal conditioning circuits.
How does the keying (K) option on the TFC-105-02-FM-D-A-K prevent assembly mistakes?
The keying option adds a polarization tab that physically prevents the connector from being inserted in the wrong orientation or into an unkeyed adjacent connector. This is especially valuable in compact boards with multiple 10-position connectors where visual differentiation is difficult. Keying eliminates the risk of reversed signal connections that could damage sensitive circuits or cause system malfunction during test or field service.
Which design scenarios benefit most from the TFC-105-02-FM-D-A-K's PEG mounting option?
The PEG mounting option provides a mechanical locating peg that engages a corresponding hole in the PCB, ensuring accurate placement and preventing connector rotation during soldering. This is particularly beneficial in automated SMT assembly lines where precise connector registration is needed, and in designs subject to mechanical vibration such as industrial motion controllers or vehicle-mounted electronics where post-solder mechanical retention matters.
