What are the key features of TFM-147-02-L-D-LC?
- Tiger Eye dual-beam contacts on 0.050" (1.27 mm) pitch sustain low contact resistance across hundreds of mating cycles, supporting reliable high-speed signals in 94-position board-to-board interfaces
- Board-lock (LC) retention posts press into PCB holes, mechanically anchoring the connector against mating forces and vibration independent of the SMT solder joints
- Low-profile vertical SMT orientation enables thin mezzanine stacking with minimal height above the PCB, conserving z-axis space in compact embedded computing and instrumentation designs
What is TFM-147-02-L-D-LC used for?
The TFM-147-02-L-D-LC is designed for high-density vertical mezzanine interconnections in FPGA carrier boards, telecommunications equipment, and compact embedded systems where 94 signals must pass through a single low-profile connector. Its board-lock feature ensures mechanical robustness in rack-mounted and portable instruments subject to vibration and repeated daughtercard insertions. The 0.050" pitch and surface-mount termination allow this connector to serve as a high-pin-count backbone in system-on-module and daughtercard designs while maintaining a minimal PCB footprint.

Frequently Asked Questions
For a compact FPGA module requiring 90+ signals, how does TFM-147-02-L-D-LC fit within a tight PCB height budget?
The TFM-147-02-L-D-LC uses a low-profile vertical SMT orientation that minimizes the height above the PCB surface, keeping mezzanine stack height well below what taller high-profile variants would require. With 94 positions on 0.050" (1.27 mm) pitch in a dual-row layout, it routes over 90 signals in a connector body roughly 2.4 inches long, allowing FPGA module designers to maintain a thin form factor while meeting high channel count requirements.
How does the board-lock retention on TFM-147-02-L-D-LC protect the 94-position SMT connector in a vibration environment?
The board-lock posts on TFM-147-02-L-D-LC press into drilled PCB holes and act as mechanical anchors that carry lateral and pull-out loads, preventing the connector body from shifting during vibration or repeated mating cycles. This protection is critical for the 94 SMT solder joints, which are vulnerable to cracking under cyclic mechanical stress without a secondary anchor, making the LC variant preferable for industrial and rack-mounted systems operating from -55°C to +125°C.
How does TFM-147-02-L-D-LC compare to a 0.100" pitch 94-position connector in terms of PCB footprint area?
At 0.050" (1.27 mm) pitch, the TFM-147-02-L-D-LC occupies roughly one-quarter the PCB connector area that a 0.100" pitch dual-row connector would need to accommodate 94 positions, since the pitch is halved in both row and column directions. This significant footprint reduction frees PCB space for routing, decoupling, and other components, making the TFM-147-02-L-D-LC the preferred choice for high-density designs where a 0.100" connector would exceed the allowed connector zone dimensions.
