Frequently Asked Questions
What differentiates the TFC-141-02-L-D-A from the TFC-141-02-F-D-A in the SAMTEC TFC series?
The TFC-141-02-L-D-A features long (-L) tails while the TFC-141-02-F-D-A uses standard (-F) tails. Long tails extend beyond the PCB bottom surface by approximately 0.230", enabling wire-wrap or press-fit termination in addition to soldering, offering greater flexibility for prototyping and specialized assembly processes.
Can the SAMTEC TFC-141-02-L-D-A be used in high-cycle mating applications?
Yes. The Tiger Eye contact geometry provides a four-point wiping contact action rated for hundreds of mating cycles, maintaining contact resistance below 20 milliohms across 82 positions. This makes the TFC-141-02-L-D-A suitable for test fixtures and field-replaceable module applications requiring repeated mating.
What current and voltage ratings apply to the SAMTEC TFC-141-02-L-D-A connector?
Each pin in the TFC-141-02-L-D-A is rated at 1 A of current capacity. The connector operates at signal-level voltages, typically up to 125 VAC/VDC, covering the full range of logic-level and low-power signal applications in embedded computing, industrial control, and data acquisition PCBs with 82 signal lines.
