Frequently Asked Questions
How many positions and what pitch does the TFM-149-01-L-D-LC offer for fine-pitch mezzanine designs?
The TFM-149-01-L-D-LC provides 98 contact positions in a dual-row layout with 1.27 mm (0.050 inch) pitch. This fine pitch enables high pin-count mezzanine and board-to-board interconnects in compact PCB designs used in aerospace, military, and industrial computing equipment.
What makes the Tiger Eye contact technology in TFM-149-01-L-D-LC suitable for high-reliability environments?
Tiger Eye contacts on the TFM-149-01-L-D-LC provide robust mechanical engagement and consistent low contact resistance across 98 positions during repeated mating cycles. This makes the connector well-suited for aerospace avionics and military systems that must maintain signal integrity under vibration, shock, and wide temperature swings.
When should a PCB designer choose the 1.27 mm pitch TFM-149-01-L-D-LC over a 2.54 mm pitch connector?
A designer should specify the TFM-149-01-L-D-LC when PCB area is limited and the design requires 98 or more signal positions. The 1.27 mm pitch reduces the connector footprint to roughly half the board space of a 2.54 mm pitch alternative, making it practical for dense FPGA daughtercards, high-channel data acquisition modules, and compact avionics boards.
