Frequently Asked Questions
What contact count and pitch does the TFC-137-02-FM-D-K-TR support?
The TFC-137-02-FM-D-K-TR supports 74 positions in a dual-row arrangement at 0.050" (1.27 mm) pitch. This configuration delivers high signal density per millimeter of connector length, making it well suited for FPGA daughter cards, high-speed parallel buses, and compact embedded modules where pin count and board real estate are both constrained.
What does the FM designation mean in TFC-137-02-FM-D-K-TR and how does it affect mating?
The FM designation stands for Female Metal contacts, indicating precision machined female receptacles that mate with male pin headers. These metal contacts in the TFC-137-02-FM-D-K-TR provide better contact retention force and lower contact resistance than stamped contacts, contributing to reliable signal integrity across all 74 positions even after repeated mating cycles at 0.050" pitch.
How does the K (kinked lead) termination in TFC-137-02-FM-D-K-TR affect PCB assembly?
The K suffix indicates a kinked lead termination style that anchors the connector to the PCB surface during reflow soldering, preventing connector shift from solder surface tension or conveyor vibration. This is particularly valuable for the 74-position dual-row TFC-137-02-FM-D-K-TR, where maintaining precise 0.050" pitch alignment across the full connector length is critical during the SMT soldering process.
In which industries is the TFC-137-02-FM-D-K-TR connector commonly specified?
The TFC-137-02-FM-D-K-TR is commonly specified in telecommunications line card assemblies, industrial automation backplanes, and test and measurement instrumentation. Its 74-position count at 1.27 mm pitch supports dense signal interconnects needed in server expansion slots, FPGA evaluation platforms, and military-grade embedded computing modules requiring reliable board-to-board connections within tight form factor constraints.
