What are the key features of TFC-148-02-LM-D-K-TR?
- 96-position dual-row terminal strip at 0.050" (1.27 mm) pitch delivers the highest signal count in the TFC series for ultra-dense mezzanine interconnects
- Long machined (LM) contacts provide approximately 0.5 mm additional insertion depth compared to standard contacts for improved vibration resistance
- Tape-and-reel (TR) packaging enables automated SMT pick-and-place assembly at high production volumes with standard 12 mm carrier tape feeders
- Tiger Eye cost-effective design maintains Samtec precision machined contact quality at a lower per-pin cost for budget-sensitive high-volume applications
What is TFC-148-02-LM-D-K-TR used for?
The TFC-148-02-LM-D-K-TR is designed for ultra-high-density board-to-board interconnects in large FPGA carrier boards, multi-channel data acquisition systems, and advanced computing modules requiring 96 signal or mixed power-and-signal connections at 1.27 mm pitch. The tape-and-reel format supports high-volume automated SMT assembly for telecommunications line cards, medical imaging boards, and scientific instrument backplanes. Its long machined contacts add mechanical robustness for rack-mounted or portable equipment subject to handling vibration during shipping and field installation.

Frequently Asked Questions
What is the maximum signal count the TFC-148-02-LM-D-K-TR can route and how does the 96-pin layout compare to lower-count TFC series variants?
The TFC-148-02-LM-D-K-TR provides 96 positions arranged in 2 rows of 48 contacts each at 0.050" (1.27 mm) pitch, supporting up to 48 differential pairs or 96 single-ended signals across a body length of approximately 61 mm. Compared to the 84-position TFC-142, the 96-pin version adds 12 more contacts in roughly 8 mm of additional board length, making it the right choice when signal count exceeds 80 but a second connector on the same board edge is not acceptable due to space or routing constraints.
How do the long machined contacts in TFC-148-02-LM-D-K-TR improve reliability in field-deployed equipment?
Long machined contacts extend approximately 0.5 mm deeper into the mating receptacle compared to standard TFC contacts, increasing contact overlap and normal force during mating. This extra engagement depth reduces the probability of intermittent contact under vibration levels of 5 g to 20 g typical of rack-mounted telecom or industrial enclosures. It also improves tolerance to PCB-to-PCB coplanarity variation of up to 0.15 mm, which is common in stacked-board assemblies with thick motherboards or uneven standoff heights in a 96-pin dual-row mating scenario.
What assembly process does the TR suffix enable for TFC-148-02-LM-D-K-TR and what reel specifications apply?
The TR suffix designates tape-and-reel packaging, which configures the 96-position SMT header for automated pick-and-place placement. The components are loaded on 12 mm or wider carrier tape with standard 4 mm pitch pockets and supplied in 1000 or 2000 piece reels, depending on body size. This allows continuous SMT line feeding at placement rates typical of high-volume production without operator handling, and the tape format is compatible with IEC 60286-3 standard component tape specifications for pick-and-place machines from all major SMT equipment vendors.
In which large-scale signal processing or FPGA designs is TFC-148-02-LM-D-K-TR the preferred board connector?
The 96-position TFC-148-02-LM-D-K-TR is preferred in designs based on large FPGAs such as Xilinx UltraScale+ or Intel Stratix 10 devices, where a single high-pin-count I/O bank may drive 40 to 80 differential pairs that must be routed to a mezzanine ADC, DAC, or serializer board. Scientific instruments with 96-channel simultaneous sampling, multi-band RF front-ends with more than 32 antenna paths, and AI accelerator co-processor modules connecting to a host CPU carrier board via 96-bit wide parallel fabric are all typical use cases for this 1.27 mm pitch terminal strip.
