Frequently Asked Questions
What is the contact pitch of the TFM-146-03-SM-D-LC and how does it affect PCB layout density?
The TFM-146-03-SM-D-LC uses a 0.050" (1.27 mm) pitch between contacts. This fine pitch allows 46 positions in a dual-row arrangement to fit within a very compact PCB footprint, making it suitable for high-density designs where board space is at a premium compared to standard 2.54 mm pitch connectors.
Which PCB assembly processes are compatible with the TFM-146-03-SM-D-LC surface-mount termination?
The surface-mount (SM) termination style of the TFM-146-03-SM-D-LC is compatible with standard SMT reflow soldering processes. The component can withstand typical reflow temperatures, allowing automated pick-and-place assembly. This is particularly useful in high-volume production environments where manual through-hole soldering of 46-pin dual-row connectors would be impractical.
How many total pins does the TFM-146-03-SM-D-LC provide, and what is the advantage of its dual-row layout?
The TFM-146-03-SM-D-LC provides 92 total pins arranged in 2 rows of 46 positions each at 0.050" (1.27 mm) pitch. The dual-row (D) layout doubles interconnect density compared to a single-row design of the same length, enabling more signal, power, and ground connections within the same PCB area for compact embedded and industrial applications.
