Frequently Asked Questions
What contact pitch and position count does the TFM-140-04-L-D-LC provide?
The TFM-140-04-L-D-LC features a 0.050 inch (1.27 mm) pitch with 80 positions arranged in a dual-row configuration. This high-density layout allows up to 80 signal lines within a footprint of approximately 2.0 inches in length, making it well suited for parallel data buses and multi-signal board-to-board connections in embedded computing systems.
How does the LC (low-clearance) profile of TFM-140-04-L-D-LC benefit tight board-stack designs?
The low-clearance (LC) profile of TFM-140-04-L-D-LC reduces the mated stack height compared to standard-height Tiger Eye connectors, enabling board-to-board separations as small as a few millimeters. This is critical in multi-board systems such as processor modules and FPGA carrier cards where minimizing the overall enclosure height is a mechanical design requirement, typically achieving clearances under 5 mm.
When should an engineer consider TFM-140-04-L-D-LC over a lower pin-count Tiger Eye variant?
Engineers should select TFM-140-04-L-D-LC when a design requires 80 or more simultaneous signal connections across a 0.050 inch pitch interface, such as 64-bit parallel memory buses, high-channel-count ADC boards, or multi-lane LVDS interfaces. Its dual-row 80-position configuration consolidates connectivity that would otherwise require two or more smaller connectors, reducing BOM count and improving board layout efficiency.
