Frequently Asked Questions
How many positions does the TFC-139-02-L-D-A-K-TR have and what is its pitch?
The TFC-139-02-L-D-A-K-TR features 78 positions arranged in a dual-row configuration with a 0.050-inch (1.27 mm) pitch. This compact pitch allows high-density signal routing between PCBs, making it suitable for applications where board space is limited and many signals must be interconnected simultaneously.
What assembly method is supported by the TFC-139-02-L-D-A-K-TR tape-and-reel packaging?
The TR suffix indicates tape-and-reel packaging, which is compatible with automated SMT pick-and-place assembly equipment. This packaging format is well-suited for high-volume production environments, supporting efficient board assembly processes with standard reel sizes and component feeding at speeds appropriate for modern SMT lines.
In which applications is the TFC-139-02-L-D-A-K-TR Tiger Eye terminal strip typically used?
This connector is commonly used in telecommunications equipment, embedded computing modules, and industrial control boards where reliable board-to-board interconnection is required at 78 signals or more. The 0.050-inch pitch and dual-row layout make it particularly effective for daughter card interfaces, backplane connections, and high-pin-count module sockets operating at standard logic signal levels.
How does the Tiger Eye contact design benefit the TFC-139-02-L-D-A-K-TR's mating reliability?
The Tiger Eye contact design used in the TFC-139-02-L-D-A-K-TR provides a wiping action during mating that clears contaminants from contact surfaces, delivering consistent low contact resistance over multiple insertion cycles. This design improves reliability in field-replaceable module applications and ensures stable signal integrity across all 78 positions at standard signal voltages up to the connector's rated level.
