Frequently Asked Questions
How many pins does the TFM-141-03-SM-D-RA provide, and how are they arranged?
The TFM-141-03-SM-D-RA is a dual-row right-angle surface-mount connector with 82 pins total, arranged as 41 pins per row on a 0.50 mm pitch. This fine-pitch dual-row layout enables high signal density for compact board-to-board interconnects in embedded computing modules and data-acquisition systems.
What signal frequencies can the TFM-141-03-SM-D-RA support in high-speed board-to-board designs?
The SAMTEC TFM-141-03-SM-D-RA is rated for high-speed signal routing and can support differential pairs operating at multi-GHz frequencies, with SAMTEC characterizing TFM series connectors up to 20 GHz in controlled impedance layouts. Its 82 pins and 0.50 mm pitch allow dense routing of both low-voltage logic and high-speed differential signals on adjacent PCBs.
When should designers choose the right-angle TFM-141-03-SM-D-RA over a vertical board-to-board connector?
Designers should select the right-angle TFM-141-03-SM-D-RA when two PCBs must be oriented perpendicular to each other and the interconnect must remain within the profile of the host board. With 82 pins at 0.50 mm pitch and a 3 mm mated stack height, it suits backplane daughter-card assemblies, industrial controller modules, and compact instrumentation where vertical clearance is limited.
