What are the key features of TFM-148-11-FM-D?
- 96 positions (48 per row) on an ultra-fine 0.050" (1.27 mm) pitch for high-density SMT interconnects
- Female machined contacts (FM) deliver tight tolerances and extended mating cycle reliability
- Dual-row (D suffix) layout maximizes signal density while minimizing connector footprint
- Tiger Eye high-reliability contact design engineered for demanding aerospace, defense, and industrial environments
- Compatible with SAMTEC TFM and TSM mating header series for flexible board-stacking configurations
What is TFM-148-11-FM-D used for?
TFM-148-11-FM-D is used in aerospace avionics, defense electronics, and high-reliability industrial control systems where a 96-pin, 0.050" pitch fine-pitch terminal strip must handle vibration, shock, and extended thermal cycling. It is also well suited for FPGA mezzanine cards, high-channel-count data acquisition modules, and space-constrained communications boards requiring maximum signal density from a compact dual-row SMT header.

Frequently Asked Questions
What pin count and pitch does TFM-148-11-FM-D provide for board-to-board signal interconnects?
TFM-148-11-FM-D provides 96 positions (48 positions per row) on a dual-row 0.050" (1.27 mm) pitch. This fine pitch delivers high signal density in a very compact SMT footprint, enabling FPGA daughter cards, avionics modules, and data acquisition boards to route 96 pins where a standard 0.100" pitch connector would require twice the board length.
Why choose female machined contacts in TFM-148-11-FM-D over stamped-contact alternatives for high-reliability designs?
The FM suffix on TFM-148-11-FM-D denotes female machined contacts, which are turned from solid pin stock to achieve tighter dimensional tolerances than stamped contacts. In aerospace or defense applications with thousands of mating cycles and wide temperature swings from -55°C to +125°C, machined contacts maintain consistent contact resistance and mechanical retention where stamped contacts could deform or loosen.
In what high-reliability applications does TFM-148-11-FM-D outperform standard pitch connectors?
TFM-148-11-FM-D excels in avionics line-replaceable modules, satellite payloads, and military embedded computing boards where a 96-pin, 0.050" pitch dual-row interface must withstand MIL-STD vibration profiles and thermal shock between -55°C and +125°C. Standard 0.100" pitch connectors cannot match this pin density in the same board area, making the Tiger Eye fine-pitch design essential for size, weight, and power (SWaP) constrained platforms.
How does TFM-148-11-FM-D compare to the TFM series lower pin-count variants for procurement planning?
TFM-148-11-FM-D occupies the high-density end of the Tiger Eye TFM family at 96 pins total and 0.050" pitch. Procurement teams selecting between TFM variants should match position count to the actual signal count — undersizing wastes I/O while oversizing wastes board space on the 1.27 mm pitch footprint. SAMTEC's TFM series supports custom position counts, and the -11- stack height code further defines the mated board separation for the specific mechanical envelope.
