What are the key features of TFM-146-05-L-D-LC?
- 92-position dual-row SMT terminal strip at 0.050" (1.27 mm) pitch enables very high pin density in approximately 59 mm of board length
- Low-profile (L) body height minimizes mated stack height for ultra-slim enclosure designs with clearance under 5 mm
- Tiger Eye contact design maintains contact resistance below 20 mΩ across all 92 positions through repeated thermal and mechanical cycling
- RoHS-compliant matte tin plating and gold-over-nickel options available to meet application reliability and shelf-life requirements
What is TFM-146-05-L-D-LC used for?
The TFM-146-05-L-D-LC is deployed in ultra-slim embedded systems, portable medical devices, and mobile computing modules where a 92-pin low-profile SMT connector at 1.27 mm pitch is needed to maintain minimal board-to-board clearance. FPGA development platforms and high-speed signal acquisition boards use this connector to route wide parallel buses across stacked PCBs with minimal vertical footprint. Its low-profile form factor also suits wearable electronics and industrial handheld devices where total enclosure thickness is constrained to under 15 mm.

Frequently Asked Questions
How does the low-profile designation affect the mated stack height of TFM-146-05-L-D-LC in slim device assemblies?
The low-profile (L) body of the TFM-146-05-L-D-LC reduces the mated board-to-board clearance to approximately 3 to 4 mm compared to 5 mm or more for standard-height variants, enabling use in portable medical devices and mobile computing modules with total PCB stack heights under 10 mm.
What is the maximum pin count and approximate footprint length of TFM-146-05-L-D-LC for FPGA carrier board designs?
The TFM-146-05-L-D-LC provides 92 positions in a dual-row layout at 1.27 mm pitch, occupying approximately 59 mm of PCB length with a row-to-row spacing of 2.54 mm. This lets FPGA carrier designers route 46 differential signal pairs or a mix of power and data lines in a single connector footprint.
Which industrial or medical applications specify TFM-146-05-L-D-LC for high-reliability SMT connectivity?
Portable patient monitoring devices, handheld industrial scanners, and mobile data logging instruments specify the TFM-146-05-L-D-LC because its Tiger Eye contacts maintain contact resistance below 20 mΩ across all 92 positions over a -55°C to +125°C operating range, meeting the reliability requirements of IEC 60068 vibration and thermal cycling tests.
When is TFM-146-05-L-D-LC preferable over a 0.100" pitch connector for a 92-channel board-to-board link?
At 1.27 mm pitch, TFM-146-05-L-D-LC achieves the same 92-channel capacity in roughly half the PCB footprint area of a standard 2.54 mm pitch connector, making it the preferred choice when board real estate is scarce, overall connector length must remain under 60 mm, and a low-profile mated height below 5 mm is required.
