What are the key features of TFC-124-02-FM-D-A-K-TR?
- 48 positions in dual-row layout at 1.27mm (0.050") pitch delivers high signal density in half the footprint of 2.54mm connectors for compact PCBs
- Tiger Eye contact geometry provides reliable wiping action with gold-plated contacts, maintaining low contact resistance below 20mΩ across the rated mating cycles
- Tape-and-reel (TR) packaging enables high-volume automated pick-and-place assembly, reducing per-unit handling cost in production runs
- Dual-row (D) SMD design supports high-speed signal routing up to several GHz by minimizing stub length and parasitic inductance at 0.050" pitch
What is TFC-124-02-FM-D-A-K-TR used for?
TFC-124-02-FM-D-A-K-TR is used in high-density FPGA, SoC, and DSP board designs where 48 signals must be routed between two PCBs in less than 30mm of connector width. Its 1.27mm pitch is standard on memory module edge slots, mezzanine daughter-card interfaces, and high-speed backplane applications operating at signal frequencies from DC to several GHz. The tape-and-reel format ensures consistent placement accuracy required for fine-pitch SMD connectors in automated production lines.

Frequently Asked Questions
What pitch and pin count does TFC-124-02-FM-D-A-K-TR offer for high-density board interconnects?
TFC-124-02-FM-D-A-K-TR is a 48-position dual-row terminal strip with 1.27mm (0.050") pitch, providing a high contact density that fits 48 signal or power connections in approximately 30mm of board length. The 0.050" pitch is half the density of standard 2.54mm headers, making it ideal for compact FPGA mezzanine and daughter-card designs where board real estate is limited.
How does SAMTEC's Tiger Eye contact design in TFC-124-02-FM-D-A-K-TR affect signal integrity at high frequencies?
The Tiger Eye contact geometry uses a dual-beam wiping action that maintains consistent contact force and keeps contact resistance below 20mΩ throughout the connector's mating life. This low resistance and the minimal stub length at 1.27mm pitch help preserve signal integrity for high-speed differential pairs and single-ended signals up to several GHz, making TFC-124-02-FM-D-A-K-TR suitable for PCIe, LVDS, and SERDES interfaces on mezzanine cards.
Why is tape-and-reel (TR) packaging important for TFC-124-02-FM-D-A-K-TR in volume production?
The tape-and-reel (TR) packaging of TFC-124-02-FM-D-A-K-TR allows automated pick-and-place machines to place the fine-pitch 1.27mm connector with positioning accuracy within ±0.05mm, which is critical for reliable solder joint formation on 48 pads. Tape-and-reel also reduces per-unit handling time compared to tray or tube packaging, cutting assembly cost on production volumes of 1000 units or more.
In which board-to-board interface scenarios is TFC-124-02-FM-D-A-K-TR a more space-efficient choice than a 2.54mm pitch connector?
When a design requires 48 signal connections between two PCBs, TFC-124-02-FM-D-A-K-TR at 1.27mm pitch occupies approximately 30mm of board edge, compared to roughly 60mm for a 2.54mm pitch dual-row connector with the same pin count. This 50% length reduction is decisive for compact FPGA daughter cards, embedded compute modules, and RF test fixtures where the mating connector row length directly limits board miniaturization.
