Frequently Asked Questions
How many pins does TFM-146-04-FM-D-LC provide and at what pitch spacing?
The TFM-146-04-FM-D-LC features 92 total positions in a dual-row arrangement at a 1.27 mm (0.050") pitch. This high pin density allows complex signal buses to be routed through a compact connector footprint, making it suitable for FPGA I/O boards and high-channel-count data acquisition modules.
For what high-reliability applications is TFM-146-04-FM-D-LC specifically designed?
TFM-146-04-FM-D-LC is designed for aerospace avionics, defense electronics, and industrial control systems where connector reliability under vibration and thermal stress is critical. Its Tiger Eye contacts provide multiple redundant contact points across all 92 positions, ensuring uninterrupted signal paths in environments with sustained mechanical shock or temperature cycling.
How does TFM-146-04-FM-D-LC differ from standard dual-row 2.54 mm pitch terminal strips in terms of board space savings?
The TFM-146-04-FM-D-LC operates at 1.27 mm pitch versus the 2.54 mm pitch of standard terminal strips, reducing the connector's board footprint by approximately 50% for the same 92-position count. This makes it a strong choice when migrating dense signal interfaces to compact next-generation PCB designs without sacrificing pin count.
