Key Features
- 22-position dual-row connector at 0.050" (1.27 mm) pitch with key (K) feature preventing incorrect mating and protecting 11 contact pairs
- Formed (F) termination style provides reliable through-hole solder joints for secure mechanical and electrical PCB attachment
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly in high-volume production runs with consistent component orientation
Applications
The TFC-111-02-F-D-A-K-TR is suited for compact board-to-board and module interconnections in embedded systems, IoT devices, and industrial sensor nodes requiring 22 positions at 0.050" pitch. The key alignment feature prevents mating errors in field service and production assembly, while the tape-and-reel packaging supports automated SMT pick-and-place manufacturing. Its 11 contact pairs can carry mixed signal and low-power applications within a minimal PCB footprint.

Frequently Asked Questions
What is the significance of the K suffix in TFC-111-02-F-D-A-K-TR for automated assembly and field service?
The K suffix denotes a keying or polarization feature that physically prevents incorrect mating of the 22-position connector. In automated assembly this ensures consistent orientation during robotic insertion, while in field service environments it protects sensitive circuits from reversed connections. The key feature is especially valuable when 11 contact pairs carry mixed power and signal lines that would be damaged by misalignment.
How does formed (F) termination in TFC-111-02-F-D-A-K-TR differ from surface mount termination for PCB attachment strength?
The formed (F) termination style on TFC-111-02-F-D-A-K-TR uses bent solder tails that insert into PTH pads on the PCB, providing through-hole solder joints for all 22 positions. This delivers significantly higher mechanical pull strength compared to SMT pads, making it preferable in applications subject to connector mating forces, repeated plug-unplug cycles, or mechanical stress that would risk lifting SMT pads.
For a production run of 50,000 units using TFC-111-02-F-D-A-K-TR, what packaging advantage does the TR variant offer?
The tape-and-reel (TR) packaging of TFC-111-02-F-D-A-K-TR provides each 22-position connector in a standardized carrier tape, enabling automated pick-and-place machines to process thousands of components per hour without manual handling. For a 50,000-unit production run, TR packaging reduces placement cycle time, minimizes ESD and contamination risk, and typically reduces per-unit assembly cost compared to bulk or tube-packaged alternatives.
