What are the key features of TFM-147-03-S-D-LC?
- 47-position dual-row layout at 0.050 inch (1.27 mm) pitch delivering 94 contacts in a compact PCB footprint
- Integrated latching cover (LC) provides positive mechanical lock preventing accidental unmating under vibration or shock
- Tiger Eye contact design ensures consistent retention force and low contact resistance below 20 milliohms per pin
What is TFM-147-03-S-D-LC used for?
The TFM-147-03-S-D-LC is designed for high-density signal routing in FPGA mezzanine boards, multi-channel data acquisition modules, and rugged embedded computing platforms where 94 contacts must be reliably connected in a tight PCB area. The latching cover secures the mated connector pair against mechanical shock and vibration, making it suitable for avionics test equipment, industrial robotics controllers, and portable ruggedized instruments.

Frequently Asked Questions
With 94 total contacts at 0.050 inch pitch, how much PCB length does the TFM-147-03-S-D-LC occupy?
The TFM-147-03-S-D-LC has 47 positions per row at a 0.050 inch (1.27 mm) pitch, resulting in a row length of approximately 58 mm. This high contact density allows 94 signals to be routed through a connector that would need roughly 120 mm of board edge at standard 0.100 inch pitch, making it a significant space-saving solution for compact PCB designs.
In what rugged or high-vibration applications is the latching cover on the TFM-147-03-S-D-LC most beneficial?
The latching cover (LC) is most valuable in avionics test fixtures, industrial robots, and vehicular embedded systems where mechanical vibration or shock could dislodge standard friction-fit connectors. The positive-lock mechanism maintains the mated state and keeps contact resistance below 20 milliohms per pin even during vibration levels typical of MIL-STD-810 test conditions, preventing signal interruption in critical 94-pin interfaces.
How does TFM-147-03-S-D-LC compare to a 0.100 inch pitch alternative when routing dense FPGA I/O?
At 0.050 inch (1.27 mm) pitch, the TFM-147-03-S-D-LC routes 94 contacts in approximately half the board area required by a 0.100 inch pitch connector with the same pin count. For FPGA mezzanine boards that must bring out 80 to 100 I/O signals, this fine pitch saves enough PCB real estate to add additional filtering capacitors or routing layers, reducing overall board cost by eliminating the need for a larger form factor.
What procurement options are available for the TFM-147-03-S-D-LC in prototype and volume quantities?
SAMTEC supplies the TFM-147-03-S-D-LC through its authorized global distribution network with quantities from 1 piece for prototyping up to reel quantities of several hundred for production. Standard lead times are typically 1 to 4 weeks, and SAMTEC's same-day shipment program covers many catalog items. Volume pricing tiers begin at around 100 pieces, with further discounts for orders exceeding 500 units.
