Frequently Asked Questions
How many positions and what pitch does the TFC-135-02-FM-D-A-K-TR support for fine-pitch PCB interconnects?
The TFC-135-02-FM-D-A-K-TR provides 70 positions on a 0.050" (1.27 mm) dual-row pitch, with a body length of 1.875 inches. This allows routing up to 70 independent signal channels in a compact footprint, suitable for FPGA expansion buses, processor daughter cards, and high-density backplane connectors in embedded computing and industrial automation designs.
What contact material and finish make the TFC-135-02-FM-D-A-K-TR suitable for repeated mating cycles?
The TFC-135-02-FM-D-A-K-TR uses phosphor bronze contacts with a gold-plated mating surface (3 µin minimum) that delivers low contact resistance and reliable electrical performance over thousands of insertion and withdrawal cycles. The Tiger Eye contact geometry provides controlled wiping action, removing surface oxides during mating and maintaining signal integrity in 70-position fine-pitch 0.050" applications.
When would a designer choose TFC-135-02-FM-D-A-K-TR over a standard 0.100" pitch header for a 70-signal interface?
A designer would select the TFC-135-02-FM-D-A-K-TR when PCB board area is constrained and 70 signals must be routed in under 1.875 inches at 0.050" pitch versus the 3.5 inches a 0.100" header would require. The gold-mated Tiger Eye contacts sustain performance in high-cycle test fixtures and field-replaceable modules, while the peg board mounting option locks the connector in place during reflow soldering, preventing tombstoning on fine-pitch pads.
