Frequently Asked Questions
What is the contact pitch and row count of the TFC-123-02-F-D-A-K-TR, and how does that affect PCB routing density?
The TFC-123-02-F-D-A-K-TR has a 0.050 inch (1.27 mm) pitch with 2 rows, providing 46 total positions in a compact footprint. This pitch is a widely adopted standard for fine-pitch terminal strips, allowing dense signal routing while maintaining manufacturability with standard PCB design rules.
How does Samtec's Tiger Eye contact design in the TFC-123-02-F-D-A-K-TR benefit high-cycle mating applications?
The Tiger Eye contact geometry features a curved beam that provides consistent normal force over thousands of mating cycles, maintaining reliable electrical contact even after repeated insertions. This design is particularly valuable in test fixtures and removable daughtercard applications where 46-position connectors are mated and unmated frequently during product development or field servicing.
Is the TFC-123-02-F-D-A-K-TR suitable for automated SMT assembly lines, and what packaging format does it ship in?
Yes, the TFC-123-02-F-D-A-K-TR is supplied on tape-and-reel (TR) packaging, making it directly compatible with standard SMT pick-and-place equipment. This allows high-volume PCB assembly lines to place the 46-position connector alongside other surface-mount components without manual intervention, reducing assembly cost per board.
What current rating per pin can be expected for the TFC-123-02-F-D-A-K-TR terminal strip?
Samtec terminal strips at 0.050 inch pitch typically support a current rating of approximately 1 A per contact for signal-level applications, with mating tin or gold contacts maintaining low contact resistance below 20 milliohms. Designers should derate per-pin current when routing multiple adjacent pins to manage thermal dissipation across the 46-position array on the PCB.
