Frequently Asked Questions
What is the total pin count and pitch of the TFM-146-05-STL-D-LC?
The TFM-146-05-STL-D-LC has 92 total pins arranged in a dual-row layout with 46 positions per row at a 0.050 inch (1.27 mm) pitch. This high pin density makes it suitable for compact signal-intensive designs in embedded systems and networking hardware.
How does the straddle mount design of TFM-146-05-STL-D-LC benefit PCB layout engineers?
The STL (straddle mount) configuration of the TFM-146-05-STL-D-LC straddles the PCB edge, reducing the footprint needed on the board surface. It supports board thicknesses typically in the range of 0.062 inches and eliminates the need for additional mechanical retention features, saving space and assembly time.
When would a designer choose TFM-146-05-STL-D-LC over a board-to-board socket connector?
Designers choose the TFM-146-05-STL-D-LC when they need a 92-pin board edge connection that accommodates repeated mating cycles up to 30 cycles minimum without a dedicated receptacle on the mating board. Its 0.050 inch pitch allows higher density than standard 0.100 inch alternatives, making it preferable in space-constrained mezzanine card applications.
